specific purpose of a persuasive speech

Module 5: Choosing and Researching a Topic

Finding the purpose and central idea of your speech, learning objectives.

• Identify the specific purpose of a speech.
• Explain how to formulate a central idea statement for a speech.

General Purpose

The general purpose of most speeches will fall into one of four categories: to inform , to persuade , to entertain , and to commemorate or celebrate . The first step of defining the purpose of your speech is to think about which category best describes your  overall  goal with the speech. What do you want your audience to think, feel, or do as a consequence of hearing you speak? Often, the general purpose of your speech will be defined by the speaking situation. If you’re asked to run a training session at work, your purpose isn’t to entertain but rather to inform. Likewise, if you are invited to introduce the winner of an award, you’re not trying to change the audience’s mind about something; you’re honoring the recipient of the award. In a public speaking class, your general purpose may be included in the assignment: for instance, “Give a persuasive speech about . . . .”  When you’re assigned a speech project, you should always make sure you know whether the general purpose is included in the assignment or whether you need to decide on the general purpose yourself.

Specific Purpose

Now that you know your general purpose (to inform, to persuade, or to entertain), you can start to move in the direction of the specific purpose. A specific purpose statement builds on your general purpose and makes it more specific (as the name suggests). So if your first speech is an informative speech, your general purpose will be to inform your audience  about a very specific realm of knowledge.

In writing your specific purpose statement, you will take three contributing elements and bring them together to help you determine your specific purpose :

• You (your interests, your background, experience, education, etc.)
• Your audience
• The context or setting

There are three elements that combine to create a specific purpose statements: your own interests and knowledge, the interests and needs of your audience, and the context or setting in which you will be speaking.

Keeping these three inputs in mind, you can begin to write a specific purpose statement, which will be the foundation for everything you say in the speech and a guide for what you do not say. This formula will help you in putting together your specific purpose statement:

To _______________ [ Specific Communication Word (inform, explain, demonstrate, describe, define, persuade, convince, prove, argue)] _______________ [ Target Audience (my classmates, the members of the Social Work Club, my coworkers] __________________. [ The Content (how to bake brownies, that Macs are better than PCs].

Example: The purpose of my presentation is to demonstrate to  my coworkers the value of informed intercultural communication .

Formulating a Central Idea Statement

While you will not actually say your specific purpose statement during your speech, you will need to clearly state what your focus and main points are going to be. The statement that reveals your main points is commonly known as the central idea statement (or just the central idea). Just as you would create a thesis statement for an essay or research paper, the central idea statement helps focus your presentation by defining your topic, purpose, direction, angle, and/or point of view. Here are two examples:

• Central Idea—When elderly persons lose their animal companions, they can experience serious psychological, emotional, and physical effects.
• Central Idea—Your computer keyboard needs regular cleaning to function well, and you can achieve that in four easy steps.

Please note that your central idea will emerge and evolve as you research and write your speech, so be open to where your research takes you and anticipate that formulating your central idea will be an ongoing process.

Below are four guidelines for writing a strong central idea.

• Your central idea should be one, full sentence.
• Your central idea should be a statement, not a question.
• Your central idea should be specific and use concrete language.
• Each element of your central idea should be related to the others.

Using the topic “Benefits of Yoga for College Students’ Stress,” here are some correct and incorrect ways to write a central idea.

A strong central idea shows that your speech is focused around a clear and concise topic and that you have a strong sense of what you want your audience to know and understand as a result of your speech. Again, it is unlikely that you will have a final central idea before you begin your research. Instead, it will come together as you research your topic and develop your main points.

15 Formulating a Specific Purpose Statement

Now that you know your general purpose (to inform, to persuade, or to entertain), you can start to move in the direction of the specific purpose. A specific purpose statement builds on your general purpose (such as to inform) and makes it more specific (as the name suggests). So if your first speech is an informative speech, your general purpose will be to inform your audience about a very specific realm of knowledge, for example, the history of NASA’s Shuttle program.

In writing your specific purpose statement, you will take three contributing elements that will come together to help you determine your specific purpose. The diagram in Figure 4.1 shows those three elements. These three elements are you (your interests, your background, past jobs, experience, education, major), your audience (which you learned to analyze in Chapter 2), and the context or setting (also discussed in Chapter 2).

An old adage states, “Write about what you know.” In many ways, that is a great place to start with creating a speech, although you will need to con- sult other sources as well. If you start with ideas that reflect your interests, goals, and passions, that passion and commitment will come across in your speech, give you more credibility in the eyes of your audience, and make your speech more interesting.

This would be a good place for you to do an inventory. Retail stores do regular inventories to know what is “really there” in the stores. You have much more going on in your brain and background than you can be conscious of at any one time. Being asked the right kinds of prompts can help you find ideas. Figure 4.2 is a list of prompts for this inventory. To help generate some ideas for your speeches, complete the phrases and/or answer the questions in Figure 4.2 to see if any ideas can be generated from experiences or interests you may not have realized you had.

This inventory may seem long and intrusive, but digging a little deeper may help you find ideas and directions that are unique to you. You want to find this kind of subject matter and not the same topics others will gravitate towards just because they saw a list on Google on informative speech topics. Also, generating your list based on these questions and prompts will get you excited about your topic and talking about it to your class- mates. For example, a very common persuasive speech topic is organ donation. There is nothing wrong with that topic per se and it is an important issue. However, if you ask yourself the right questions, you may come up with something far more central to who you are and that might interest and/or apply to the audience more.

Another approach that you might find helpful is to determine what you are passionate about through two binary routes. First, you will obviously be passionate about the things you love, so taIt lk about those. Is The Simpsons your favorite TV show? Then you can inform us on the people and vision of the team behind this highly popular and long-running TV show. Do you feel that Big Brothers Big Sisters is a vital organization in the way it helps kids? Then persuade us to volunteer there. Conversely, you can also be passionate about things you don’t love (i.e., hate). Does it really annoy you when people don’t use their turn signals? Then persuade us to always use them. Do you want to scream when you hear a cell phone go off at the movies? Then persuade us that cell phones should be banned in theaters.

The Audience

Of course, what you love or hate may be in stark contrast to how your audience feels, so it is important to keep them in mind as well, which brings us to the next contributing factor. After you examine what you know and are passionate about, you have to determine if and how the topic has practical value or interest for others. It may be that it is a topic the audience is not immediately interested in but needs to know about for their own benefit. Then it becomes necessary for you to find that angle and approach that will help them see the benefit of the topic and listen to you. The more you know about your audience, the better you can achieve this goal. Good speakers are very knowledgeable about their audiences.

The Context

Many aspects come into the context of a speech, but as mentioned in Chapter 2, the main ones are the time, place, and reason(s) for the event and the audience being there. Your classroom speeches have a fairly set context: time limits, the classroom, assignment specifications. Other speeches you will give in college (or in your career and personal life) will require you to think more deeply about the context just as you would the audience.

Putting It Together

Keeping these three inputs in mind, you can begin to write a specific purpose statement, which will be the foundation for everything you say in the speech and a guide for what you do not say. This formula will help you in putting together your specific purpose statement:

Specific Communication Word (in infinitive phrase) (to in- form, to explain, to demonstrate, to describe, to define, to persuade, to convince, to prove, to argue)

Target Audience (my classmates, the members of the Social Work Club, my coworkers)

The Content (how to bake brownies, that Macs are better than PCs)

Each of these parts of the specific purpose is important. The first two parts make sure you are clear on your purpose and know specifically who will be hearing your message. However, we will focus on the last part here.

The content part of the specific purposes statement must first be singular and focused, and the content must match the purpose. The word “and” really should not appear in the specific purpose statement since that would make it seem that you have two purposes and two topics. Obviously, the specific purpose statement’s content must be very narrowly defined and, well, specific. One mistake beginning speakers often make is to try to “cover” too much material. They tend to speak about the whole alphabet, A-Z on a subject, instead of just “T” or “L.” This comes from an emphasis on the topic more than the purpose, and from not keeping audience and context in mind. In other words, go deep (specific), not broad. Examples in this chapter will show what that means.

Second, the content must match the focus of the purpose word. A common error is to match an informative purpose with a persuasive content clause or phrase. For example,

To explain to my classmates why term life insurance is a better option than whole life insurance policies.

To inform my classmates about how the recent Supreme Court decision on police procedures during arrests is unconstitutional.

Sometimes it takes an unbiased second party to see where your content and purpose may not match.

Third, the specific purpose statement should be relevant to the audience. How does the purpose and its topic touch upon their lives, wallets, relationships, careers, etc.? It is also a good idea to keep in mind what you want the audience to walk away with or what you want them to know, to be able to do, to think, to act upon, or to respond to your topic—your ultimate outcome or result.

To revisit an earlier example, “to explain to my classmates the history of NASA” would be far too much material and the audience may be unsure of its relevance. A more specific one such as “to inform my classmates about the decline of the Shuttle program” would be more manageable and closer to their experience. It would also reference two well-known historical tragedies involving the Shuttle program, the Challenger Disaster in 1986 and the Columbia Explosion in 2003. Here are several examples of specific purposes statements. Notice how they meet the standards of being singular, focused, relevant, and consistent.

To inform my classmates of the origin of the hospice movement. To describe to my coworkers the steps to apply for retirement.

To define for a group of new graduate students the term “academic freedom.”

To explain to the Lions Club members the problems faced by veterans of the wars in Iraq and Afghanistan.

To persuade the members of the Greek society to take the spring break trip to Daytona Beach.

To motivate my classmates to engage in the College’s study abroad program.

To convince my classroom audience that they need at least seven hours of sleep per night to do well in their studies.

Now that you understand the basic form and function of a specific purpose statement, let’s revisit the original diagram in Figure 4.1. The same topic for a different audience will create a somewhat different specific purpose statement. Public speaking is not a “one-size-fits-all” proposition. Let’s take the subject of participating in the study abroad program. How would you change your approach if you were addressing first-semester freshmen instead of first-semester juniors? Or if you were speaking to high school students in one of the college’s feeder high schools? Or if you were asked to share your experiences with a local civic group that gave you a partial scholarship to participate in the program? You would have slightly different specific purpose statements although your experience and basic information are all the same.

For another example, let’s say that one of your family members has benefited from being in the Special Olympics and you have volunteered two years at the local event. You could give a tribute (commemorative speech) about the work of Special Olympics (with the purpose to inspire), an informative speech on the scope or history of the Special Olympics, or a per suasive speech on why audience members should volunteer at next year’s event. “Special Olympics” is a key word in every specific purpose, but the statements would otherwise be different.

Despite all the information given about specific purpose statements so far, the next thing you read will seem strange: Never start your speech by saying your specific purpose to the audience. In a sense, it is just for you and the instructor. For you, it’s like a note you might tack on the mirror or refrigerator to keep you on track. For the instructor, it’s a way for him or her to know you are accomplishing both the assignment and what you set out to do. Avoid the temptation to default to saying it at the beginning of your speech. It will seem awkward and repetitive.

8.2  The Topic, General Purpose, Specific Purpose, and Thesis

Before any work can be done on crafting the body of your speech or presentation, you must first do some prep work—selecting a topic, formulating a general purpose, a specific purpose statement, and crafting a central idea, or thesis statement. In doing so, you lay the foundation for your speech by making important decisions about what you will speak about and for what purpose you will speak. These decisions will influence and guide the entire speechwriting process, so it is wise to think carefully and critically during these beginning stages.

Understanding the General Purpose

Before any work on a speech can be done, the speaker needs to understand the general purpose of the speech.  The general purpose is what the speaker hopes to accomplish and will help guide in the selection of a topic. The instructor generally provides the general purpose for a speech, which falls into one of three categories. A general purpose to inform would mean that the speaker is teaching the audience about a topic, increasing their understanding and awareness, or providing new information about a topic the audience might already know.  Informative speeches are designed to present the facts, but not give the speaker’s opinion or any call to action. A general purpose to persuade would mean that the speaker is choosing the side of a topic and advocating for their side or belief.  The speaker is asking the audience to believe in their stance, or to take an action in support of their topic. A general purpose to entertain often entails short speeches of ceremony, where the speaker is connecting the audience to the celebration. You can see how these general purposes are very different.  An informative speech is just facts, the speaker would not be able to provide an opinion or direction on what to do with the information, whereas a persuasive speech includes the speaker’s opinions and direction on what to do with the information. Before a speaker chooses a topic, they must first understand the general purpose.

Selecting a Topic

Generally, speakers focus on one or more interrelated topics—relatively broad concepts, ideas, or problems that are relevant for particular audiences. The most common way that speakers discover topics is by simply observing what is happening around them—at their school, in their local government, or around the world. Opportunities abound for those interested in engaging speech as a tool for change. Perhaps the simplest way to find a topic is to ask yourself a few questions, including:

• What important events are occurring locally, nationally, and internationally?
• What do I care about most?
• Is there someone or something I can advocate for?
• What makes me angry/happy?
• What beliefs/attitudes do I want to share?
• Is there some information the audience needs to know?

Students speak about what is interesting to them and their audiences. What topics do you think are relevant today? There are other questions you might ask yourself, too, but these should lead you to at least a few topical choices. The most important work that these questions do is to locate topics within your pre-existing sphere of knowledge and interest. Topics should be ideas that interest the speaker or are part of their daily lives.  In order for a topic to be effective, the speaker needs to have some credibility or connection to the topic; it would be unfair to ask the audience to donate to a cause that the speaker has never donated to.  There must be a connection to the topic for the speaker to be seen as credible. David Zarefsky (2010) also identifies brainstorming as a way to develop speech topics, a strategy that can be helpful if the questions listed above did not yield an appropriate or interesting topic. Brainstorming involves looking at your daily activities to determine what you could share with an audience.  Perhaps if you work out regularly or eat healthy, you could explain that to an audience, or demonstrate how to dribble a basketball.  If you regularly play video games, you may advocate for us to take up video games or explain the history of video games.  Anything that you find interesting or important might turn into a topic. Starting with a topic you are already interested in will make writing and presenting your speech a more enjoyable and meaningful experience. It means that your entire speechwriting process will focus on something you find important and that you can present this information to people who stand to benefit from your speech. At this point, it is also important to consider the audience before choosing a topic.  While we might really enjoy a lot of different things that could be topics, if the audience has no connection to that topic, then it wouldn’t be meaningful for the speaker or audience.  Since we always have a diverse audience, we want to make sure that everyone in the audience can gain some new information from the speech.  Sometimes, a topic might be too complicated to cover in the amount of time we have to present, or involve too much information then that topic might not work for the assignment, and finally if the audience can not gain anything from a topic then it won’t work.  Ultimately, when we choose a topic we want to pick something that we are familiar with and enjoy, we have credibility and that the audience could gain something from. Once you have answered these questions and narrowed your responses, you are still not done selecting your topic. For instance, you might have decided that you really care about breeds of dogs. This is a very broad topic and could easily lead to a dozen different speeches. To resolve this problem, speakers must also consider the audience to whom they will speak, the scope of their presentation, and the outcome they wish to achieve.

Formulating the Purpose Statements

By honing in on a very specific topic, you begin the work of formulating your purpose statement. In short, a purpose statement clearly states what it is you would like to achieve. Purpose statements are especially helpful for guiding you as you prepare your speech. When deciding which main points, facts, and examples to include, you should simply ask yourself whether they are relevant not only to the topic you have selected, but also whether they support the goal you outlined in your purpose statement. The general purpose statement of a speech may be to inform, to persuade, to celebrate, or to entertain. Thus, it is common to frame a specific purpose statement around one of these goals. According to O’Hair, Stewart, and Rubenstein, a specific purpose statement “expresses both the topic and the general speech purpose in action form and in terms of the specific objectives you hope to achieve” (2004). The specific purpose is a single sentence that states what the audience will gain from this speech, or what will happen at the end of the speech. The specific purpose is a combination of the general purpose and the topic and helps the speaker to focus in on what can be achieved in a short speech.

To go back to the topic of a dog breed, the general purpose might be to inform, a specific purpose might be: To inform the audience about how corgis became household pets. If the general purpose is to persuade the specific purpose might be: to persuade the audience that dog breeds deemed “dangerous” should not be excluded from living in the cities. In short, the general purpose statement lays out the broader goal of the speech while the specific purpose statement describes precisely what the speech is intended to do.  The specific purpose should focus on the audience and be measurable, if I were to ask the audience before I began the speech how many people know how corgis became household pets, they could raise their hand, and if I ask at the end of my speech how many people know how corgis became household pets, I should see a lot more hands.  The specific purpose is the “so what” of the speech, it helps the speaker focus on the audience and take a bigger idea of a topic and narrow it down to what can be accomplished in a short amount of time.

Writing the Thesis Statement

The specific purpose statement is a tool that you will use as you write your speech, but it is unlikely that it will appear verbatim in your speech. Instead, you will want to convert the specific purpose statement into a central idea, or thesis statement that you will share with your audience.  Just like in a written paper, where the thesis comes in the first part of the paper, in a speech, the thesis comes within the first few sentences of the speech.  The thesis must be stated and tells the audience what to expect in this speech. A thesis statement may encapsulate the main idea of a speech in just a sentence or two and be designed to give audiences a quick preview of what the entire speech will be about. The thesis statement should be a single, declarative statement followed by a separate preview statement. If you are a Harry Potter enthusiast, you may write a thesis statement (central idea) the following way using the above approach: J.K. Rowling is a renowned author of the Harry Potter series with a Cinderella-like story of a rise to fame.

Writing the Preview Statement

A preview statement (or series of statements) is a guide to your speech. This is the part of the speech that literally tells the audience exactly what main points you will cover. If you were to get on any freeway, there would be a green sign on the side of the road that tells you what cities are coming up—this is what your preview statement does; it tells the audience what points will be covered in the speech. Best of all, you would know what to look for! So, if we take our J.K Rowling example, the thesis and preview would look like this: J.K. Rowling is a renowned author of the Harry Potter series with a Cinderella-like rags-to-riches story. First, I will tell you about J.K. Rowling’s humble beginnings. Then, I will describe her personal struggles as a single mom. Finally, I will explain how she overcame adversity and became one of the richest women in the United Kingdom.

Writing the Body of Your Speech

Once you have finished the important work of deciding what your speech will be about, as well as formulating the purpose statement and crafting the thesis, you should turn your attention to writing the body of your speech. The body of your speech consists of 3–4 main points that support your thesis and help the audience to achieve the specific purpose.  Creating main points helps to chunk the information you are sharing with your audience into an easy-to-understand organization. Choosing your main points will help you focus in on what information you want to share with the audience in order to prove your thesis. Since we can’t tell the audience everything about our topic, we need to choose our main points to make sure we can share the most important information with our audience. All of your main points are contained in the body, and normally this section is prepared well before you ever write the introduction or conclusion. The body of your speech will consume the largest amount of time to present, and it is the opportunity for you to elaborate on your supporting evidence, such as facts, statistics, examples, and opinions that support your thesis statement and do the work you have outlined in the specific purpose statement. Combining these various elements into a cohesive and compelling speech, however, is not without its difficulties, the first of which is deciding which elements to include and how they ought to be organized to best suit your purpose.

13 Specific Purpose

Learning Objectives

• Create a specific purpose to determine speech goals.

What Is Your Purpose?

There are two purposes for public speaking: general and specific. Purpose statements are especially helpful for guiding you as you prepare your speech. The general purpose refers to the broad goal for creating and delivering the speech. The specific purpose, on the other hand, starts with one of those broad goals and then further informs the listener about the who ,  what ,  when ,  where ,  why , and  how of the speech. The specific purpose answers the question: What do you want to accomplish by the end of your speech?

The specific purpose is the combination of factors that make speeches and other discourse meaningful and a useful way to change the way something is. It is stated as a sentence incorporating the general purpose, the specific audience for the speech, and a prepositional phrase that summarizes the topic. Suppose you are going to give a speech about using open-source software. Here are two examples, each with a similar topic but a different general purpose and a different audience:

In each of these examples, you will notice that there is a general purpose (to inform or to persuade); the specific purpose follows the goal of the speech and allows the speaker to fine-tune their purpose by being more specific.  Before you can think strategically about your speech content, you need to know what your specific purpose is. Once you have decided on the topic, intention, and general purpose of your speech, you can begin to write your specific purpose statement. You will not state this purpose verbatim in your speech but you will use it to craft a thesis statement that you will state verbatim in your speech.

Write your general and specific purpose for your informative speech now.

Key Takeaways

Specific purposes are important to the speech making process.

• Your specific purpose will support your speech by informing the listener about your speech and the goals of your speech.
• You may not specifically state the specific purpose but it will guide your intention of the speech.
• The specific purpose will help guide your speech. You can always refer back to the specific purpose if you begin to “get in the weeds” with your information, research, and support.
• Ask yourself: What do you want to accomplish by the end of your speech?

Persuasive Speech Outline, with Examples

March 17, 2021 - Gini Beqiri

A persuasive speech is a speech that is given with the intention of convincing the audience to believe or do something. This could be virtually anything – voting, organ donation, recycling, and so on.

A successful persuasive speech effectively convinces the audience to your point of view, providing you come across as trustworthy and knowledgeable about the topic you’re discussing.

So, how do you start convincing a group of strangers to share your opinion? And how do you connect with them enough to earn their trust?

Topics for your persuasive speech

We’ve made a list of persuasive speech topics you could use next time you’re asked to give one. The topics are thought-provoking and things which many people have an opinion on.

When using any of our persuasive speech ideas, make sure you have a solid knowledge about the topic you’re speaking about – and make sure you discuss counter arguments too.

Here are a few ideas to get you started:

• All school children should wear a uniform
• Facebook is making people more socially anxious
• It should be illegal to drive over the age of 80
• Lying isn’t always wrong
• The case for organ donation

Read our full list of  75 persuasive speech topics and ideas .

Preparation: Consider your audience

As with any speech, preparation is crucial. Before you put pen to paper, think about what you want to achieve with your speech. This will help organise your thoughts as you realistically can only cover 2-4 main points before your  audience get bored .

It’s also useful to think about who your audience are at this point. If they are unlikely to know much about your topic then you’ll need to factor in context of your topic when planning the structure and length of your speech. You should also consider their:

• Cultural or religious backgrounds
• Shared concerns, attitudes and problems
• Shared interests, beliefs and hopes
• Baseline attitude – are they hostile, neutral, or open to change?

The factors above will all determine the approach you take to writing your speech. For example, if your topic is about childhood obesity, you could begin with a story about your own children or a shared concern every parent has. This would suit an audience who are more likely to be parents than young professionals who have only just left college.

Remember the 3 main approaches to persuade others

There are three main approaches used to persuade others:

The ethos approach appeals to the audience’s ethics and morals, such as what is the ‘right thing’ to do for humanity, saving the environment, etc.

Pathos persuasion is when you appeal to the audience’s emotions, such as when you  tell a story  that makes them the main character in a difficult situation.

The logos approach to giving a persuasive speech is when you appeal to the audience’s logic – ie. your speech is essentially more driven by facts and logic. The benefit of this technique is that your point of view becomes virtually indisputable because you make the audience feel that only your view is the logical one.

• Ethos, Pathos, Logos: 3 Pillars of Public Speaking and Persuasion

Ideas for your persuasive speech outline

1. structure of your persuasive speech.

The opening and closing of speech are the most important. Consider these carefully when thinking about your persuasive speech outline. A  strong opening  ensures you have the audience’s attention from the start and gives them a positive first impression of you.

You’ll want to  start with a strong opening  such as an attention grabbing statement, statistic of fact. These are usually dramatic or shocking, such as:

Sadly, in the next 18 minutes when I do our chat, four Americans that are alive will be dead from the food that they eat – Jamie Oliver

Another good way of starting a persuasive speech is to include your audience in the picture you’re trying to paint. By making them part of the story, you’re embedding an emotional connection between them and your speech.

You could do this in a more toned-down way by talking about something you know that your audience has in common with you. It’s also helpful at this point to include your credentials in a persuasive speech to gain your audience’s trust.

Obama would spend hours with his team working on the opening and closing statements of his speech.

2. Stating your argument

You should  pick between 2 and 4 themes  to discuss during your speech so that you have enough time to explain your viewpoint and convince your audience to the same way of thinking.

It’s important that each of your points transitions seamlessly into the next one so that your speech has a logical flow. Work on your  connecting sentences  between each of your themes so that your speech is easy to listen to.

Your argument should be backed up by objective research and not purely your subjective opinion. Use examples, analogies, and stories so that the audience can relate more easily to your topic, and therefore are more likely to be persuaded to your point of view.

3. Addressing counter-arguments

Any balanced theory or thought  addresses and disputes counter-arguments  made against it. By addressing these, you’ll strengthen your persuasive speech by refuting your audience’s objections and you’ll show that you are knowledgeable to other thoughts on the topic.

When describing an opposing point of view, don’t explain it in a bias way – explain it in the same way someone who holds that view would describe it. That way, you won’t irritate members of your audience who disagree with you and you’ll show that you’ve reached your point of view through reasoned judgement. Simply identify any counter-argument and pose explanations against them.

4. Closing your speech

Your closing line of your speech is your last chance to convince your audience about what you’re saying. It’s also most likely to be the sentence they remember most about your entire speech so make sure it’s a good one!

The most effective persuasive speeches end  with a  call to action . For example, if you’ve been speaking about organ donation, your call to action might be asking the audience to register as donors.

Practice answering AI questions on your speech and get  feedback on your performance .

If audience members ask you questions, make sure you listen carefully and respectfully to the full question. Don’t interject in the middle of a question or become defensive.

You should show that you have carefully considered their viewpoint and refute it in an objective way (if you have opposing opinions). Ensure you remain patient, friendly and polite at all times.

To persuade my audience to start walking in order to improve their health.

Central idea

Regular walking can improve both your mental and physical health.

Introduction

Let’s be honest, we lead an easy life: automatic dishwashers, riding lawnmowers, T.V. remote controls, automatic garage door openers, power screwdrivers, bread machines, electric pencil sharpeners, etc., etc. etc. We live in a time-saving, energy-saving, convenient society. It’s a wonderful life. Or is it?

Example 2: Persuasive speech

Tips for delivering your persuasive speech

• Practice, practice, and practice some more . Record yourself speaking and listen for any nervous habits you have such as a nervous laugh, excessive use of filler words, or speaking too quickly.
• Show confident body language . Stand with your legs hip width apart with your shoulders centrally aligned. Ground your feet to the floor and place your hands beside your body so that hand gestures come freely. Your audience won’t be convinced about your argument if you don’t sound confident in it. Find out more about  confident body language here .
• Don’t memorise your speech word-for-word  or read off a script. If you memorise your persuasive speech, you’ll sound less authentic and panic if you lose your place. Similarly, if you read off a script you won’t sound genuine and you won’t be able to connect with the audience by  making eye contact . In turn, you’ll come across as less trustworthy and knowledgeable. You could simply remember your key points instead, or learn your opening and closing sentences.
• Remember to use facial expressions when storytelling  – they make you more relatable. By sharing a personal story you’ll more likely be speaking your truth which will help you build a connection with the audience too. Facial expressions help bring your story to life and transport the audience into your situation.
• Keep your speech as concise as possible . When practicing the delivery, see if you can edit it to have the same meaning but in a more succinct way. This will keep the audience engaged.

The best persuasive speech ideas are those that spark a level of controversy. However, a public speech is not the time to express an opinion that is considered outside the norm. If in doubt, play it safe and stick to topics that divide opinions about 50-50.

Bear in mind who your audience are and plan your persuasive speech outline accordingly, with researched evidence to support your argument. It’s important to consider counter-arguments to show that you are knowledgeable about the topic as a whole and not bias towards your own line of thought.

Chapter 5: Presentation Organization

32 Purpose and Central Idea Statements

Speeches have traditionally been seen to have one of three broad purposes: to inform, to persuade, and — well, to be honest, different words are used for the third kind of speech purpose: to inspire, to amuse, to please, or to entertain. These broad goals are commonly known as a speech’s general purpose, since, in general, you are trying to inform, persuade, or entertain your audience without regard to specifically what the topic will be. Perhaps you could think of them as appealing to the understanding of the audience (informative), the will or action (persuasive), and the emotion or pleasure.

Now that you know your general purpose (to inform, to persuade, or to entertain), you can start to move in the direction of the specific purpose. A specific purpose statement builds on your general purpose (to inform) and makes it more specific (as the name suggests). So if your first speech is an informative speech, your general purpose will be to inform your audience about a very specific realm of knowledge.

In writing your specific purpose statement, you will take three contributing elements (shown in figure 5.3) that will come together to help you determine your specific purpose :

• You (your interests, your background, past jobs, experience, education, major),
• Your audience
• The context or setting.

Putting It Together

Keeping these three inputs in mind, you can begin to write a specific purpose statement , which will be the foundation for everything you say in the speech and a guide for what you do not say. This formula will help you in putting together your specific purpose statement:

To _______________ [Specific Communication Word (inform, explain, demonstrate, describe, define, persuade, convince, prove, argue)] my [ Target Audience (my classmates, the members of the Social Work Club, my coworkers]  __________________. [T he Content (how to bake brownies, that Macs are better than PCs].

Example: The purpose of my presentation is to demonstrate for my coworkers the value of informed intercultural communication.

Formulating a Central Idea Statement

While you will not actually say your specific purpose statement during your speech, you will need to clearly state what your focus and main points are going to be. The statement that reveals your main points is commonly known as the central idea statement (or just the central idea). Just as you would create a thesis statement for an essay or research paper, the central idea statement helps focus your presentation by defining your topic, purpose, direction, angle and/or point of view. Here are two examples:

Specific Purpose –  To explain to my classmates the effects of losing a pet on the elderly.

Central Idea –  When elderly persons lose their animal companions, they can experience serious psychological, emotional, and physical effects.

Specific Purpose –  To demonstrate to my audience the correct method for cleaning a computer keyboard.

Central Idea –  Your computer keyboard needs regular cleaning to function well, and you can achieve that in four easy steps.

Speechwriting

8 Purpose and Thesis

Speechwriting Essentials

In this chapter . . .

As discussed in the chapter on Speaking Occasion , speechwriting begins with careful analysis of the speech occasion and its given circumstances, leading to the choice of an appropriate topic. As with essay writing, the early work of speechwriting follows familiar steps: brainstorming, research, pre-writing, thesis, and so on.

This chapter focuses on techniques that are unique to speechwriting. As a spoken form, speeches must be clear  about the purpose and main idea or “takeaway.” Planned redundancy means that you will be repeating these elements several times over during the speech.

Furthermore, finding purpose and thesis are essential whether you’re preparing an outline for extemporaneous delivery or a completely written manuscript for presentation. When you know your topic, your general and specific purpose, and your thesis or central idea, you have all the elements you need to write a speech that is focused, clear, and audience friendly.

Recognizing the General Purpose

Speeches have traditionally been grouped into one of three categories according to their primary purpose: 1) to inform, 2) to persuade, or 3) to inspire, honor, or entertain. These broad goals are commonly known as the  general purpose of a speech . Earlier, you learned about the actor’s tool of intention or objectives. The general purpose is like a super-objective; it defines the broadest goal of a speech. These three purposes are not necessarily exclusive to the others. A speech designed to be persuasive can also be informative and entertaining. However, a speech should have one primary goal. That is its general purpose.

Why is it helpful to talk about speeches in such broad terms? Being perfectly clear about what you want your speech to do or make happen for your audience will keep you focused. You can make a clearer distinction between whether you want your audience to leave your speech knowing more (to inform), or  ready to take action (to persuade), or feeling something (to inspire)

It’s okay to use synonyms for these broad categories. Here are some of them:

• To inform could be to explain, to demonstrate, to describe, to teach.
• To persuade could be to convince, to argue, to motivate, to prove.
• To inspire might be to honor, or entertain, to celebrate, to mourn.

In summary, the first question you must ask yourself when starting to prepare a speech is, “Is the primary purpose of my speech to inform, to persuade, or to inspire?”

Articulating Specific Purpose

A specific purpose statement builds upon your general purpose and makes it specific (as the name suggests). For example, if you have been invited to give a speech about how to do something, your general purpose is “to inform.”  Choosing a topic appropriate to that general purpose, you decide to speak about how to protect a personal from cyberattacks. Now you are on your way to identifying a specific purpose.

A good specific purpose statement has three elements: goal, target audience, and content.

If you think about the above as a kind of recipe, then the first two “ingredients” — your goal and your audience — should be simple. Words describing the target audience should be as specific as possible. Instead of “my peers,” you could say, for example, “students in their senior year at my university.”

The third ingredient in this recipe is content, or what we call the topic of your speech. This is where things get a bit difficult. You want your content to be specific and something that you can express succinctly in a sentence. Here are some common problems that speakers make in defining the content, and the fix:

Now you know the “recipe” for a specific purpose statement. It’s made up of  T o, plus an active W ord, a specific  A udience, and clearly stated  C ontent. Remember this formula: T + W + A + C.

A: for a group of new students

C: the term “plagiarism”

Here are some further examples a good specific purpose statement:

• To explain to a group of first-year students how to join a school organization.
• To persuade the members of the Greek society to take a spring break trip in Daytona Beach.
• To motivate my classmates in English 101 to participate in a study abroad program.
• To convince first-year students that they need at least seven hours of sleep per night to do well in their studies.
• To inspire my Church community about the accomplishments of our pastor.

The General and Specific Purpose Statements are writing tools in the sense that they help you, as a speechwriter, clarify your ideas.

Creating a Thesis Statement

Once you are clear about your general purpose and specific purpose, you can turn your attention to crafting a thesis statement. A thesis is the central idea in an essay or a speech. In speechwriting, the thesis or central idea explains the message of the content. It’s the speech’s “takeaway.” A good thesis statement will also reveal and clarify the ideas or assertions you’ll be addressing in your speech (your main points). Consider this example:

General Purpose: To persuade. Specific Purpose: To motivate my classmates in English 101 to participate in a study abroad program. Thesis: A semester-long study abroad experience produces lifelong benefits by teaching you about another culture, developing your language skills, and enhancing your future career prospects.

The difference between a specific purpose statement and a thesis statement is clear in this example. The thesis provides the takeaway (the lifelong benefits of study abroad). It also points to the assertions that will be addressed in the speech. Like the specific purpose statement, the thesis statement is a writing tool. You’ll incorporate it into your speech, usually as part of the introduction and conclusion.

All good expository, rhetorical, and even narrative writing contains a thesis. Many students and even experienced writers struggle with formulating a thesis. We struggle when we attempt to “come up with something” before doing the necessary research and reflection. A thesis only becomes clear through the thinking and writing process. As you develop your speech content, keep asking yourself: What is important here? If the audience can remember only one thing about this topic, what do I want them to remember?

Example #2: General Purpose: To inform Specific Purpose: To demonstrate to my audience the correct method for cleaning a computer keyboard. Central Idea: Your computer keyboard needs regular cleaning to function well, and you can achieve that in four easy steps.

Example # 3 General Purpose: To Inform Specific Purpose: To describe how makeup is done for the TV show The Walking Dead . Central Idea: The wildly popular zombie show The Walking Dead achieves incredibly scary and believable makeup effects, and in the next few minutes I will tell you who does it, what they use, and how they do it.

Notice in the examples above that neither the specific purpose nor the central idea ever exceeds one sentence. If your central idea consists of more than one sentence, then you are probably including too much information.

Problems to Avoid

The first problem many students have in writing their specific purpose statement has already been mentioned: specific purpose statements sometimes try to cover far too much and are too broad. For example:

“To explain to my classmates the history of ballet.”

Aside from the fact that this subject may be difficult for everyone in your audience to relate to, it’s enough for a three-hour lecture, maybe even a whole course. You’ll probably find that your first attempt at a specific purpose statement will need refining. These examples are much more specific and much more manageable given the limited amount of time you’ll have.

• To explain to my classmates how ballet came to be performed and studied in the U.S.
• To explain to my classmates the difference between Russian and French ballet.
• To explain to my classmates how ballet originated as an art form in the Renaissance.
• To explain to my classmates the origin of the ballet dancers’ clothing.

The second problem happens when the “communication verb” in the specific purpose does not match the content; for example, persuasive content is paired with “to inform” or “to explain.” Can you find the errors in the following purpose statements?

• To inform my audience why capital punishment is unconstitutional. (This is persuasive. It can’t be informative since it’s taking a side)
• To persuade my audience about the three types of individual retirement accounts. (Even though the purpose statement says “persuade,” it isn’t persuading the audience of anything. It is informative.)
• To inform my classmates that Universal Studios is a better theme park than Six Flags over Georgia. (This is clearly an opinion; hence it is a persuasive speech and not merely informative)

The third problem exists when the content part of the specific purpose statement has two parts. One specific purpose is enough. These examples cover two different topics.

• To explain to my audience how to swing a golf club and choose the best golf shoes.
• To persuade my classmates to be involved in the Special Olympics and vote to fund better classes for the intellectually disabled.

To fix this problem of combined or hybrid purposes, you’ll need to select one of the topics in these examples and speak on that one alone.

The fourth problem with both specific purpose and central idea statements is related to formatting. There are some general guidelines that need to be followed in terms of how you write out these elements of your speech:

• Don’t write either statement as a question.
• Always use complete sentences for central idea statements and infinitive phrases (beginning with “to”) for the specific purpose statement.
• Use concrete language (“I admire Beyoncé for being a talented performer and businesswoman”) and avoid subjective or slang terms (“My speech is about why I think Beyoncé is the bomb”) or jargon and acronyms (“PLA is better than CBE for adult learners.”)

There are also problems to avoid in writing the central idea statement. As mentioned above, remember that:

• The specific purpose and central idea statements are not the same thing, although they are related.
• The central idea statement should be clear and not complicated or wordy; it should “stand out” to the audience. As you practice delivery, you should emphasize it with your voice.
• The central idea statement should not be the first thing you say but should follow the steps of a good introduction as outlined in the next chapters.

You should be aware that all aspects of your speech are constantly going to change as you move toward the moment of giving your speech. The exact wording of your central idea may change, and you can experiment with different versions for effectiveness. However, your specific purpose statement should not change unless there is a good reason to do so. There are many aspects to consider in the seemingly simple task of writing a specific purpose statement and its companion, the central idea statement. Writing good ones at the beginning will save you some trouble later in the speech preparation process.

6.4 Specific Purposes

Learning objectives.

• Understand the process of extending a general purpose into a specific purpose.
• Integrate the seven tips for creating specific purposes.

Once you have chosen your general purpose and your topic, it’s time to take your speech to the next phase and develop your specific purpose. A specific purpose A statement starting with one of the three general purposes (to inform, to persuade, or to entertain), but is then followed by a specification of one’s audience, the actual topic a speaker has chosen, and the basic objective the speaker hopes to accomplish with the speech. starts with one of the three general purposes and then specifies the actual topic you have chosen and the basic objective you hope to accomplish with your speech. Basically, the specific purpose answers the who , what , when , where , and why questions for your speech.

Getting Specific

When attempting to get at the core of your speech (the specific purpose), you need to know a few basic things about your speech. First, you need to have a general purpose. Once you know whether your goal is to inform, persuade, or entertain, picking an appropriate topic is easier. Obviously, depending on the general purpose, you will have a range of different types of topics. For example, let’s say you want to give a speech about hygiene. You could still give a speech about hygiene no matter what your general purpose is, but the specific purpose would vary depending on whether the general purpose is to inform (discussing hygiene practices around the globe), to persuade (discussing why people need to adopt a specific hygiene practice), or to entertain (discussing some of the strange and unique hygiene practices that people have used historically). Notice that in each of these cases, the general purpose alters the topic, but all three are still fundamentally about hygiene.

Now, when discussing specific purposes, we are concerned with who, what, when, where, why, and how questions for your speech. Let’s examine each of these separately. First, you want to know who is going to be in your audience. Different audiences, as discussed in the chapter on audience analysis, have differing desires, backgrounds, and needs. Keeping your audience first and foremost in your thoughts when choosing a specific purpose will increase the likelihood that your audience will find your speech meaningful.

Second is the “what” question, or the basic description of your topic. When picking an effective topic, you need to make sure that the topic is appropriate for a variety of constraints or limitations within a speaking context.

Third, you need to consider when your speech will be given. Different speeches may be better for different times of the day. For example, explaining the importance of eating breakfast and providing people with cereal bars may be a great topic at 9:00 a.m. but may not have the same impact if you’re giving it at 4:00 p.m.

Fourth, you need to consider where your speech will be given. Are you giving a speech in front of a classroom? A church? An executive meeting? Depending on the location of your speech, different topics may or may not be appropriate.

The last question you need to answer within your speech is why. Why does your audience need to hear your speech? If your audience doesn’t care about your specific purpose, they are less likely to attend to your speech. If it’s a topic that’s a little more off-the-wall, you’ll really need to think about why they should care.

Once you’ve determined the who , what , when , where , and why aspects of your topic, it’s time to start creating your actual specific purpose. First, a specific purpose, in its written form, should be a short, declarative sentence that emphasizes the main topic of your speech. Let’s look at an example:

In this example, we’ve quickly narrowed a topic from a more general topic to a more specific topic. Let’s now look at that topic in terms of a general purpose and specific purpose:

For the purpose of this example, we used the same general topic area, but demonstrated how you could easily turn the topic into either an informative speech or a persuasive speech. In the first example, the speaker is going to talk about the danger embedded journalists face. In this case, the speaker isn’t attempting to alter people’s ideas about embedded journalists, just make them more aware of the dangers. In the second case, the specific purpose is to persuade a group of journalism students (the audience) to avoid jobs as embedded journalists.

Your Specific Statement of Purpose

To form a clear and succinct statement of the specific purpose of your speech, start by naming your general purpose (to inform, to persuade, or to entertain). Follow this by a capsule description of your audience (my peers in class, a group of kindergarten teachers, etc.). Then complete your statement of purpose with a prepositional phrase (a phrase using “to,” “about,” “by,” or another preposition) that summarizes your topic. As an example, “My specific purpose is to persuade the students in my residence hall to protest the proposed housing cost increase” is a specific statement of purpose, while “My speech will be about why we should protest the proposed housing cost increase” is not.

Specific purposes should be statements, not questions. If you find yourself starting to phrase your specific purpose as a question, ask yourself how you can reword it as a statement. Table 6.3 "My Specific Purpose Is…" provides several more examples of good specific purpose statements.

Table 6.3 My Specific Purpose Is…

Basic Tips for Creating Specific Purposes

Now that we’ve examined what specific purposes are, we are going to focus on a series of tips to help you write specific purposes that are appropriate for a range of speeches.

Audience, Audience, Audience

First and foremost, you always need to think about your intended audience when choosing your specific purpose. In the previous section, we talked about a speech where a speaker is attempting to persuade a group of journalism students to not take jobs as embedded journalists. Would the same speech be successful, or even appropriate, if given in your public speaking class? Probably not. As a speaker, you may think your topic is great, but you always need to make sure you think about your audience when selecting your specific purpose. For this reason, when writing your specific purpose, start off your sentence by including the words “my audience” or actually listing the name of your audience: a group of journalism students, the people in my congregation, my peers in class, and so on. When you place your audience first, you’re a lot more likely to have a successful speech.

Matching the Rhetorical Situation

After your audience, the second most important consideration about your specific purpose pertains to the rhetorical situation of your speech. The rhetorical situation The set of circumstances surrounding your speech (e.g., speaker, audience, text, and context). is the set of circumstances surrounding your speech (e.g., speaker, audience, text, and context). When thinking about your specific purpose, you want to ensure that all these components go together. You want to make sure that you are the appropriate speaker for a topic, the topic is appropriate for your audience, the text of your speech is appropriate, and the speech is appropriate for the context. For example, speeches that you give in a classroom may not be appropriate in a religious context and vice versa.

Make It Clear

The specific purpose statement for any speech should be direct and not too broad, general, or vague. Consider the lack of clarity in the following specific purpose: “To persuade the students in my class to drink more.” Obviously, we have no idea what the speaker wants the audience to drink: water, milk, orange juice? Alcoholic beverages? Furthermore, we have no way to quantify or make sense of the word “more.” “More” assumes that the students are already drinking a certain amount, and the speaker wants them to increase their intake. If you want to persuade your listeners to drink eight 8-ounce glasses of water per day, you need to say so clearly in your specific purpose.

Another way in which purpose statements are sometimes unclear comes from the use of colloquial language. While we often use colloquialisms in everyday life, they are often understood only by a limited number of people. It may sound like fun to have a specific purpose like, “To persuade my audience to get jiggy,” but if you state this as your purpose, many people probably won’t know what you’re talking about at all.

Don’t Double Up

You cannot hope to solve the entire world’s problems in one speech, so don’t even try. At the same time, you also want to make sure that you stick to one specific purpose. Chances are it will be challenging enough to inform your audience about one topic or persuade them to change one behavior or opinion. Don’t put extra stress on yourself by adding topics. If you find yourself using the word “and” in your specific topic statement, you’re probably doubling up on topics.

Can I Really Do This in Five to Seven Minutes?

When choosing your specific purpose, it’s important to determine whether it can be realistically covered in the amount of time you have. Time limits are among the most common constraints for students in a public speaking course. Usually speeches early in the term have shorter time limits (three to five minutes), and speeches later in the term have longer time limits (five to eight minutes). While eight minutes may sound like an eternity to be standing up in front of the class, it’s actually a very short period of time in which to cover a topic. To determine whether you think you can accomplish your speech’s purpose in the time slot, ask yourself how long it would take to make you an informed person on your chosen topic or to persuade you to change your behavior or attitudes.

If you cannot reasonably see yourself becoming informed or persuaded during the allotted amount of time, chances are you aren’t going to inform or persuade your audience either. The solution, of course, is to make your topic narrower so that you can fully cover a limited aspect of it.

Key Takeaways

• Moving from a general to specific purpose requires you to identify the who , what , when , where , and why of your speech.
• State your specific purpose in a sentence that includes the general purpose, a description of the intended audience, and a prepositional phrase summarizing the topic.
• When creating a specific purpose for your speech, first, consider your audience. Second, consider the rhetorical situation. Make sure your specific purpose statement uses clear language, and that it does not try to cover more than one topic.
• Make sure you can realistically accomplish your specific purpose within the allotted time.
• You’ve been asked to give a series of speeches on the importance of health care in poverty-stricken countries. One audience will consist of business men and women, one audience will consist of religious leaders, and another audience will consist of high school students. How would you need to adjust your speech’s purpose for each of these different audiences? How do these different audiences alter the rhetorical situation?
• For the following list of topics, think about how you could take the same topic and adjust it for each of the different general purposes (inform, persuade, and entertain). Write out the specific purpose for each of your new speech topics. Here are the three general topic areas to work with: the First Amendment to the US Constitution, iPods, and literacy in the twenty-first century.

7.2 The Topic, General Purpose, Specific Purpose, and Thesis

Click below to play an audio file of this section of the chapter sponsored by the Women for OSU Partnering to Impact grant.

Before any work can be done on crafting the body of your speech or presentation, you must first do some prep work—selecting a topic, formulating a general purpose, a specific purpose statement, and crafting a central idea, or thesis statement. In doing so, you lay the foundation for your speech by making important decisions about what you will speak about and for what purpose you will speak. These decisions will influence and guide the entire speechwriting process, so it is wise to think carefully and critically during these beginning stages.

Selecting a Topic

Generally, speakers focus on one or more interrelated topics—relatively broad concepts, ideas, or problems that are relevant for particular audiences. The most common way that speakers discover topics is by simply observing what is happening around them—at their school, in their local government, or around the world. Student government leaders, for example, speak or write to other students when their campus is facing tuition or fee increases, or when students have achieved something spectacular, like lobbying campus administrators for lower student fees and succeeding. In either case, it is the situation that makes their speeches appropriate and useful for their audience of students and university employees. More importantly, they speak when there is an opportunity to change a university policy or to alter the way students think or behave in relation to a particular event on campus.

But you need not run for president or student government in order to give a meaningful speech. On the contrary, opportunities abound for those interested in engaging speech as a tool for change. Perhaps the simplest way to find a topic is to ask yourself a few questions, including:

• What important events are occurring locally, nationally and internationally? • What do I care about most? • Is there someone or something I can advocate for? • What makes me angry/happy? • What beliefs/attitudes do I want to share? • Is there some information the audience needs to know?

Students speak about what is interesting to them and their audiences. What topics do you think are relevant today? There are other questions you might ask yourself, too, but these should lead you to at least a few topical choices. The most important work that these questions do is to locate topics within your pre-existing sphere of knowledge and interest. David Zarefsky (2010) also identifies brainstorming as a way to develop speech topics, a strategy that can be helpful if the questions listed above did not yield an appropriate or interesting topic. Starting with a topic you are already interested in will likely make writing and presenting your speech a more enjoyable and meaningful experience. It means that your entire speechwriting process will focus on something you find important and that you can present this information to people who stand to benefit from your speech.

Once you have answered these questions and narrowed your responses, you are still not done selecting your topic. For instance, you might have decided that you really care about breeds of dogs. This is a very broad topic and could easily lead to a dozen different speeches. To resolve this problem, speakers must also consider the audience to whom they will speak, the scope of their presentation, and the outcome they wish to achieve.

Formulating the Purpose Statements

By honing in on a very specific topic, you begin the work of formulating your purpose statement . In short, a purpose statement clearly states what it is you would like to achieve. Purpose statements are especially helpful for guiding you as you prepare your speech. When deciding which main points, facts, and examples to include, you should simply ask yourself whether they are relevant not only to the topic you have selected, but also whether they support the goal you outlined in your purpose statement. The general purpose statement of a speech may be to inform, to persuade, to celebrate, or to entertain. Thus, it is common to frame a specific purpose statement around one of these goals. According to O’Hair, Stewart, and Rubenstein, a specific purpose statement “expresses both the topic and the general speech purpose in action form and in terms of the specific objectives you hope to achieve” (2004). For instance, the home design enthusiast might write the following specific purpose statement: At the end of my speech, the audience will learn the pro’s and con’s of flipping houses. In short, the general purpose statement lays out the broader goal of the speech while the specific purpose statement describes precisely what the speech is intended to do. Some of your professors may ask that you include the general purpose and add the specific purpose.

Writing the Thesis Statement

The specific purpose statement is a tool that you will use as you write your talk, but it is unlikely that it will appear verbatim in your speech. Instead, you will want to convert the specific purpose statement into a central idea, or thesis statement that you will share with your audience.

Depending on your instructor’s approach, a thesis statement may be written two different ways. A thesis statement may encapsulate the main points of a speech in just a sentence or two, and be designed to give audiences a quick preview of what the entire speech will be about. The thesis statement for a speech, like the thesis of a research-based essay, should be easily identifiable and ought to very succinctly sum up the main points you will present. Some instructors prefer that your thesis, or central idea, be a single, declarative statement providing the audience with an overall statement that provides the essence of the speech, followed by a separate preview statement.

If you are a Harry Potter enthusiast, you may write a thesis statement (central idea) the following way using the above approach: J.K. Rowling is a renowned author of the Harry Potter series with a Cinderella like story having gone from relatively humble beginnings, through personal struggles, and finally success and fame.

Writing the Preview Statement

However, some instructors prefer that you separate your thesis from your preview statement . A preview statement (or series of statements) is a guide to your speech. This is the part of the speech that literally tells the audience exactly what main points you will cover. If you were to open your Waze app, it would tell you exactly how to get there. Best of all, you would know what to look for! So, if we take our J.K Rowling example, let’s rewrite that using this approach separating out the thesis and preview:

J.K. Rowling is a renowned author of the Harry Potter series with a Cinderella like rags to riches story. First, I will tell you about J.K. Rowling’s humble beginnings. Then, I will describe her personal struggles as a single mom. Finally, I will explain how she overcame adversity and became one of the richest women in the United Kingdom.

There is no best way to approach this. This is up to your instructor.

Writing the Body of Your Speech

Once you have finished the important work of deciding what your speech will be about, as well as formulating the purpose statement and crafting the thesis, you should turn your attention to writing the body of your speech. All of your main points are contained in the body, and normally this section is prepared well before you ever write the introduction or conclusion. The body of your speech will consume the largest amount of time to present; and it is the opportunity for you to elaborate on facts, evidence, examples, and opinions that support your thesis statement and do the work you have outlined in the specific purpose statement. Combining these various elements into a cohesive and compelling speech, however, is not without its difficulties, the first of which is deciding which elements to include and how they ought to be organized to best suit your purpose.

Public Speaking Tips & Speech Topics

How to Write an Outline for a Persuasive Speech, with Examples

Jim Peterson has over 20 years experience on speech writing. He wrote over 300 free speech topic ideas and how-to guides for any kind of public speaking and speech writing assignments at My Speech Class.

Persuasive speeches are one of the three most used speeches in our daily lives. Persuasive speech is used when presenters decide to convince their presentation or ideas to their listeners. A compelling speech aims to persuade the listener to believe in a particular point of view. One of the most iconic examples is Martin Luther King’s ‘I had a dream’ speech on the 28th of August 1963.

In this article:

What is Persuasive Speech?

Here are some steps to follow:, persuasive speech outline, final thoughts.

Persuasive speech is a written and delivered essay to convince people of the speaker’s viewpoint or ideas. Persuasive speaking is the type of speaking people engage in the most. This type of speech has a broad spectrum, from arguing about politics to talking about what to have for dinner. Persuasive speaking is highly connected to the audience, as in a sense, the speaker has to meet the audience halfway.

Persuasive Speech Preparation

Persuasive speech preparation doesn’t have to be difficult, as long as you select your topic wisely and prepare thoroughly.

1. Select a Topic and Angle

Come up with a controversial topic that will spark a heated debate, regardless of your position. This could be about anything. Choose a topic that you are passionate about. Select a particular angle to focus on to ensure that your topic isn’t too broad. Research the topic thoroughly, focussing on key facts, arguments for and against your angle, and background.

2. Define Your Persuasive Goal

Once you have chosen your topic, it’s time to decide what your goal is to persuade the audience. Are you trying to persuade them in favor of a certain position or issue? Are you hoping that they change their behavior or an opinion due to your speech? Do you want them to decide to purchase something or donate money to a cause? Knowing your goal will help you make wise decisions about approaching writing and presenting your speech.

3. Analyze the Audience

Understanding your audience’s perspective is critical anytime that you are writing a speech. This is even more important when it comes to a persuasive speech because not only are you wanting to get the audience to listen to you, but you are also hoping for them to take a particular action in response to your speech. First, consider who is in the audience. Consider how the audience members are likely to perceive the topic you are speaking on to better relate to them on the subject. Grasp the obstacles audience members face or have regarding the topic so you can build appropriate persuasive arguments to overcome these obstacles.

4. Build an Effective Persuasive Argument

Once you have a clear goal, you are knowledgeable about the topic and, have insights regarding your audience, you will be ready to build an effective persuasive argument to deliver in the form of a persuasive speech. 

Start by deciding what persuasive techniques are likely to help you persuade your audience. Would an emotional and psychological appeal to your audience help persuade them? Is there a good way to sway the audience with logic and reason? Is it possible that a bandwagon appeal might be effective?

5. Outline Your Speech

Once you know which persuasive strategies are most likely to be effective, your next step is to create a keyword outline to organize your main points and structure your persuasive speech for maximum impact on the audience.

Start strong, letting your audience know what your topic is, why it matters and, what you hope to achieve at the end of your speech. List your main points, thoroughly covering each point, being sure to build the argument for your position and overcome opposing perspectives. Conclude your speech by appealing to your audience to act in a way that will prove that you persuaded them successfully. Motivation is a big part of persuasion.

6. Deliver a Winning Speech

Select appropriate visual aids to share with your audiences, such as graphs, photos, or illustrations. Practice until you can deliver your speech confidently. Maintain eye contact, project your voice and, avoid using filler words or any form of vocal interference. Let your passion for the subject shine through. Your enthusiasm may be what sways the audience. 

Topic: What topic are you trying to persuade your audience on?

Specific Purpose:  

Central idea:

• Attention grabber – This is potentially the most crucial line. If the audience doesn’t like the opening line, they might be less inclined to listen to the rest of your speech.
• Thesis – This statement is used to inform the audience of the speaker’s mindset and try to get the audience to see the issue their way.
• Qualifications – Tell the audience why you are qualified to speak about the topic to persuade them.

After the introductory portion of the speech is over, the speaker starts presenting reasons to the audience to provide support for the statement. After each reason, the speaker will list examples to provide a factual argument to sway listeners’ opinions.

• Example 1 – Support for the reason given above.
• Example 2 – Support for the reason given above.

The most important part of a persuasive speech is the conclusion, second to the introduction and thesis statement. This is where the speaker must sum up and tie all of their arguments into an organized and solid point.

• Summary: Briefly remind the listeners why they should agree with your position.
• Memorable ending/ Audience challenge: End your speech with a powerful closing thought or recommend a course of action.
• Thank the audience for listening.

Persuasive Speech Outline Examples

Topic: Walking frequently can improve both your mental and physical health.

Specific Purpose: To persuade the audience to start walking to improve their health.

Central idea: Regular walking can improve your mental and physical health.

Life has become all about convenience and ease lately. We have dishwashers, so we don’t have to wash dishes by hand with electric scooters, so we don’t have to paddle while riding. I mean, isn’t it ridiculous?

Today’s luxuries have been welcomed by the masses. They have also been accused of turning us into passive, lethargic sloths. As a reformed sloth, I know how easy it can be to slip into the convenience of things and not want to move off the couch. I want to persuade you to start walking.

Americans lead a passive lifestyle at the expense of their own health.

• This means that we spend approximately 40% of our leisure time in front of the TV.
• Ironically, it is also reported that Americans don’t like many of the shows that they watch.
• Today’s studies indicate that people were experiencing higher bouts of depression than in the 18th and 19th centuries, when work and life were considered problematic.
• The article reports that 12.6% of Americans suffer from anxiety, and 9.5% suffer from severe depression.
• Present the opposition’s claim and refute an argument.
• Nutritionist Phyllis Hall stated that we tend to eat foods high in fat, which produces high levels of cholesterol in our blood, which leads to plaque build-up in our arteries.
• While modifying our diet can help us decrease our risk for heart disease, studies have indicated that people who don’t exercise are at an even greater risk.

In closing, I urge you to start walking more. Walking is a simple, easy activity. Park further away from stores and walk. Walk instead of driving to your nearest convenience store. Take 20 minutes and enjoy a walk around your neighborhood. Hide the TV remote, move off the couch and, walk. Do it for your heart.

Thank you for listening!

Topic: Less screen time can improve your sleep.

Specific Purpose: To persuade the audience to stop using their screens two hours before bed.

Central idea: Ceasing electronics before bed will help you achieve better sleep.

Who doesn’t love to sleep? I don’t think I have ever met anyone who doesn’t like getting a good night’s sleep. Sleep is essential for our bodies to rest and repair themselves.

I love sleeping and, there is no way that I would be able to miss out on a good night’s sleep.

As someone who has had trouble sleeping due to taking my phone into bed with me and laying in bed while entertaining myself on my phone till I fall asleep, I can say that it’s not the healthiest habit, and we should do whatever we can to change it.

• Our natural blue light source is the sun.
• Bluelight is designed to keep us awake.
• Bluelight makes our brain waves more active.
• We find it harder to sleep when our brain waves are more active.
• Having a good night’s rest will improve your mood.
• Being fully rested will increase your productivity.

Using electronics before bed will stimulate your brainwaves and make it more difficult for you to sleep. Bluelight tricks our brains into a false sense of daytime and, in turn, makes it more difficult for us to sleep. So, put down those screens if you love your sleep!

Thank the audience for listening

A persuasive speech is used to convince the audience of the speaker standing on a certain subject. To have a successful persuasive speech, doing the proper planning and executing your speech with confidence will help persuade the audience of your standing on the topic you chose. Persuasive speeches are used every day in the world around us, from planning what’s for dinner to arguing about politics. It is one of the most widely used forms of speech and, with proper planning and execution, you can sway any audience.

17.3 Organizing Persuasive Speeches

Learning objectives.

• Understand three common organizational patterns for persuasive speeches.
• Explain the steps utilized in Monroe’s motivated sequence.
• Explain the parts of a problem-cause-solution speech.
• Explain the process utilized in a comparative advantage persuasive speech.

Steven Lilley – Engaged – CC BY-SA 2.0.

Previously in this text we discussed general guidelines for organizing speeches. In this section, we are going to look at three organizational patterns ideally suited for persuasive speeches: Monroe’s motivated sequence, problem-cause-solution, and comparative advantages.

Monroe’s Motivated Sequence

One of the most commonly cited and discussed organizational patterns for persuasive speeches is Alan H. Monroe’s motivated sequence. The purpose of Monroe’s motivated sequence is to help speakers “sequence supporting materials and motivational appeals to form a useful organizational pattern for speeches as a whole” (German et al., 2010).

While Monroe’s motivated sequence is commonly discussed in most public speaking textbooks, we do want to provide one minor caution. Thus far, almost no research has been conducted that has demonstrated that Monroe’s motivated sequence is any more persuasive than other structural patterns. In the only study conducted experimentally examining Monroe’s motivated sequence, the researchers did not find the method more persuasive, but did note that audience members found the pattern more organized than other methods (Micciche, Pryor, & Butler, 2000). We wanted to add this sidenote because we don’t want you to think that Monroe’s motivated sequence is a kind of magic persuasive bullet; the research simply doesn’t support this notion. At the same time, research does support that organized messages are perceived as more persuasive as a whole, so using Monroe’s motivated sequence to think through one’s persuasive argument could still be very beneficial.

Table 17.1 “Monroe’s Motivated Sequence” lists the basic steps of Monroe’s motivated sequence and the subsequent reaction a speaker desires from his or her audience.

Table 17.1 Monroe’s Motivated Sequence

The first step in Monroe’s motivated sequence is the attention step , in which a speaker attempts to get the audience’s attention. To gain an audience’s attention, we recommend that you think through three specific parts of the attention step. First, you need to have a strong attention-getting device. As previously discussed in Chapter 9 “Introductions Matter: How to Begin a Speech Effectively” , a strong attention getter at the beginning of your speech is very important. Second, you need to make sure you introduce your topic clearly. If your audience doesn’t know what your topic is quickly, they are more likely to stop listening. Lastly, you need to explain to your audience why they should care about your topic.

In the need step of Monroe’s motivated sequence, the speaker establishes that there is a specific need or problem. In Monroe’s conceptualization of need, he talks about four specific parts of the need: statement, illustration, ramification, and pointing. First, a speaker needs to give a clear and concise statement of the problem. This part of a speech should be crystal clear for an audience. Second, the speaker needs to provide one or more examples to illustrate the need. The illustration is an attempt to make the problem concrete for the audience. Next, a speaker needs to provide some kind of evidence (e.g., statistics, examples, testimony) that shows the ramifications or consequences of the problem. Lastly, a speaker needs to point to the audience and show exactly how the problem relates to them personally.

Satisfaction

In the third step of Monroe’s motivated sequence, the satisfaction step , the speaker sets out to satisfy the need or solve the problem. Within this step, Monroe (1935) proposed a five-step plan for satisfying a need:

• Explanation
• Theoretical demonstration
• Reference to practical experience
• Meeting objections

First, you need to clearly state the attitude, value, belief, or action you want your audience to accept. The purpose of this statement is to clearly tell your audience what your ultimate goal is.

Second, you want to make sure that you clearly explain to your audience why they should accept the attitude, value, belief, or action you proposed. Just telling your audience they should do something isn’t strong enough to actually get them to change. Instead, you really need to provide a solid argument for why they should accept your proposed solution.

Third, you need to show how the solution you have proposed meets the need or problem. Monroe calls this link between your solution and the need a theoretical demonstration because you cannot prove that your solution will work. Instead, you theorize based on research and good judgment that your solution will meet the need or solve the problem.

Fourth, to help with this theoretical demonstration, you need to reference practical experience, which should include examples demonstrating that your proposal has worked elsewhere. Research, statistics, and expert testimony are all great ways of referencing practical experience.

Lastly, Monroe recommends that a speaker respond to possible objections. As a persuasive speaker, one of your jobs is to think through your speech and see what counterarguments could be made against your speech and then rebut those arguments within your speech. When you offer rebuttals for arguments against your speech, it shows your audience that you’ve done your homework and educated yourself about multiple sides of the issue.

Visualization

The next step of Monroe’s motivated sequence is the visualization step , in which you ask the audience to visualize a future where the need has been met or the problem solved. In essence, the visualization stage is where a speaker can show the audience why accepting a specific attitude, value, belief, or behavior can positively affect the future. When helping people to picture the future, the more concrete your visualization is, the easier it will be for your audience to see the possible future and be persuaded by it. You also need to make sure that you clearly show how accepting your solution will directly benefit your audience.

According to Monroe, visualization can be conducted in one of three ways: positive, negative, or contrast (Monroe, 1935). The positive method of visualization is where a speaker shows how adopting a proposal leads to a better future (e.g., recycle, and we’ll have a cleaner and safer planet). Conversely, the negative method of visualization is where a speaker shows how not adopting the proposal will lead to a worse future (e.g., don’t recycle, and our world will become polluted and uninhabitable). Monroe also acknowledged that visualization can include a combination of both positive and negative visualization. In essence, you show your audience both possible outcomes and have them decide which one they would rather have.

The final step in Monroe’s motivated sequence is the action step , in which a speaker asks an audience to approve the speaker’s proposal. For understanding purposes, we break action into two distinct parts: audience action and approval. Audience action refers to direct physical behaviors a speaker wants from an audience (e.g., flossing their teeth twice a day, signing a petition, wearing seat belts). Approval, on the other hand, involves an audience’s consent or agreement with a speaker’s proposed attitude, value, or belief.

When preparing an action step, it is important to make sure that the action, whether audience action or approval, is realistic for your audience. Asking your peers in a college classroom to donate one thousand dollars to charity isn’t realistic. Asking your peers to donate one dollar is considerably more realistic. In a persuasive speech based on Monroe’s motivated sequence, the action step will end with the speech’s concluding device. As discussed elsewhere in this text, you need to make sure that you conclude in a vivid way so that the speech ends on a high point and the audience has a sense of energy as well as a sense of closure.

Now that we’ve walked through Monroe’s motivated sequence, let’s look at how you could use Monroe’s motivated sequence to outline a persuasive speech:

Specific Purpose: To persuade my classroom peers that the United States should have stronger laws governing the use of for-profit medical experiments.

Main Points:

• Attention: Want to make nine thousand dollars for just three weeks of work lying around and not doing much? Then be a human guinea pig. Admittedly, you’ll have to have a tube down your throat most of those three weeks, but you’ll earn three thousand dollars a week.
• Need: Every day many uneducated and lower socioeconomic-status citizens are preyed on by medical and pharmaceutical companies for use in for-profit medical and drug experiments. Do you want one of your family members to fall prey to this evil scheme?
• Satisfaction: The United States should have stronger laws governing the use of for-profit medical experiments to ensure that uneducated and lower-socioeconomic-status citizens are protected.
• Visualization: If we enact tougher experiment oversight, we can ensure that medical and pharmaceutical research is conducted in a way that adheres to basic values of American decency. If we do not enact tougher experiment oversight, we could find ourselves in a world where the lines between research subject, guinea pig, and patient become increasingly blurred.
• Action: In order to prevent the atrocities associated with for-profit medical and pharmaceutical experiments, please sign this petition asking the US Department of Health and Human Services to pass stricter regulations on this preying industry that is out of control.

This example shows how you can take a basic speech topic and use Monroe’s motivated sequence to clearly and easily outline your speech efficiently and effectively.

Table 17.2 “Monroe’s Motivated Sequence Checklist” also contains a simple checklist to help you make sure you hit all the important components of Monroe’s motivated sequence.

Table 17.2 Monroe’s Motivated Sequence Checklist

Problem-Cause-Solution

Another format for organizing a persuasive speech is the problem-cause-solution format. In this specific format, you discuss what a problem is, what you believe is causing the problem, and then what the solution should be to correct the problem.

Specific Purpose: To persuade my classroom peers that our campus should adopt a zero-tolerance policy for hate speech.

• Demonstrate that there is distrust among different groups on campus that has led to unnecessary confrontations and violence.
• Show that the confrontations and violence are a result of hate speech that occurred prior to the events.
• Explain how instituting a campus-wide zero-tolerance policy against hate speech could stop the unnecessary confrontations and violence.

In this speech, you want to persuade people to support a new campus-wide policy calling for zero-tolerance of hate speech. Once you have shown the problem, you then explain to your audience that the cause of the unnecessary confrontations and violence is prior incidents of hate speech. Lastly, you argue that a campus-wide zero-tolerance policy could help prevent future unnecessary confrontations and violence. Again, this method of organizing a speech is as simple as its name: problem-cause-solution.

Comparative Advantages

The final method for organizing a persuasive speech is called the comparative advantages speech format. The goal of this speech is to compare items side-by-side and show why one of them is more advantageous than the other. For example, let’s say that you’re giving a speech on which e-book reader is better: Amazon.com’s Kindle or Barnes and Nobles’ Nook. Here’s how you could organize this speech:

Specific Purpose: To persuade my audience that the Nook is more advantageous than the Kindle.

• The Nook allows owners to trade and loan books to other owners or people who have downloaded the Nook software, while the Kindle does not.
• The Nook has a color-touch screen, while the Kindle’s screen is black and grey and noninteractive.
• The Nook’s memory can be expanded through microSD, while the Kindle’s memory cannot be upgraded.

As you can see from this speech’s organization, the simple goal of this speech is to show why one thing has more positives than something else. Obviously, when you are demonstrating comparative advantages, the items you are comparing need to be functional equivalents—or, as the saying goes, you cannot compare apples to oranges.

Key Takeaways

• There are three common patterns that persuaders can utilize to help organize their speeches effectively: Monroe’s motivated sequence, problem-cause-solution, and comparative advantage. Each of these patterns can effectively help a speaker think through his or her thoughts and organize them in a manner that will be more likely to persuade an audience.
• Alan H. Monroe’s (1935) motivated sequence is a commonly used speech format that is used by many people to effectively organize persuasive messages. The pattern consists of five basic stages: attention, need, satisfaction, visualization, and action. In the first stage, a speaker gets an audience’s attention. In the second stage, the speaker shows an audience that a need exists. In the third stage, the speaker shows how his or her persuasive proposal could satisfy the need. The fourth stage shows how the future could be if the persuasive proposal is or is not adopted. Lastly, the speaker urges the audience to take some kind of action to help enact the speaker’s persuasive proposal.
• The problem-cause-solution proposal is a three-pronged speech pattern. The speaker starts by explaining the problem the speaker sees. The speaker then explains what he or she sees as the underlying causes of the problem. Lastly, the speaker proposes a solution to the problem that corrects the underlying causes.
• The comparative advantages speech format is utilized when a speaker is comparing two or more things or ideas and shows why one of the things or ideas has more advantages than the other(s).
• Create a speech using Monroe’s motivated sequence to persuade people to recycle.
• Create a speech using the problem-cause-solution method for a problem you see on your college or university campus.
• Create a comparative advantages speech comparing two brands of toothpaste.

Persuasive Speeches — Types, Topics, and Examples

What is a persuasive speech.

In a persuasive speech, the speaker aims to convince the audience to accept a particular perspective on a person, place, object, idea, etc. The speaker strives to cause the audience to accept the point of view presented in the speech.

The success of a persuasive speech often relies on the speaker’s use of ethos, pathos, and logos.

Ethos is the speaker’s credibility. Audiences are more likely to accept an argument if they find the speaker trustworthy. To establish credibility during a persuasive speech, speakers can do the following:

Use familiar language.

Select examples that connect to the specific audience.

Utilize credible and well-known sources.

Logically structure the speech in an audience-friendly way.

Use appropriate eye contact, volume, pacing, and inflection.

Pathos appeals to the audience’s emotions. Speakers who create an emotional bond with their audience are typically more convincing. Tapping into the audience’s emotions can be accomplished through the following:

Select evidence that can elicit an emotional response.

Use emotionally-charged words. (The city has a problem … vs. The city has a disease …)

Incorporate analogies and metaphors that connect to a specific emotion to draw a parallel between the reference and topic.

Utilize vivid imagery and sensory words, allowing the audience to visualize the information.

Employ an appropriate tone, inflection, and pace to reflect the emotion.

Logos appeals to the audience’s logic by offering supporting evidence. Speakers can improve their logical appeal in the following ways:

Use comprehensive evidence the audience can understand.

Confirm the evidence logically supports the argument’s claims and stems from credible sources.

Ensure that evidence is specific and avoid any vague or questionable information.

Types of persuasive speeches

The three main types of persuasive speeches are factual, value, and policy.

A factual persuasive speech focuses solely on factual information to prove the existence or absence of something through substantial proof. This is the only type of persuasive speech that exclusively uses objective information rather than subjective. As such, the argument does not rely on the speaker’s interpretation of the information. Essentially, a factual persuasive speech includes historical controversy, a question of current existence, or a prediction:

Historical controversy concerns whether an event happened or whether an object actually existed.

Questions of current existence involve the knowledge that something is currently happening.

Predictions incorporate the analysis of patterns to convince the audience that an event will happen again.

A value persuasive speech concerns the morality of a certain topic. Speakers incorporate facts within these speeches; however, the speaker’s interpretation of those facts creates the argument. These speeches are highly subjective, so the argument cannot be proven to be absolutely true or false.

A policy persuasive speech centers around the speaker’s support or rejection of a public policy, rule, or law. Much like a value speech, speakers provide evidence supporting their viewpoint; however, they provide subjective conclusions based on the facts they provide.

How to write a persuasive speech

Incorporate the following steps when writing a persuasive speech:

Step 1 – Identify the type of persuasive speech (factual, value, or policy) that will help accomplish the goal of the presentation.

Step 2 – Select a good persuasive speech topic to accomplish the goal and choose a position .

Step 3 – Locate credible and reliable sources and identify evidence in support of the topic/position. Revisit Step 2 if there is a lack of relevant resources.

Step 4 – Identify the audience and understand their baseline attitude about the topic.

Step 5 – When constructing an introduction , keep the following questions in mind:

What’s the topic of the speech?

What’s the occasion?

Who’s the audience?

What’s the purpose of the speech?

Step 6 – Utilize the evidence within the previously identified sources to construct the body of the speech. Keeping the audience in mind, determine which pieces of evidence can best help develop the argument. Discuss each point in detail, allowing the audience to understand how the facts support the perspective.

Step 7 – Addressing counterarguments can help speakers build their credibility, as it highlights their breadth of knowledge.

Step 8 – Conclude the speech with an overview of the central purpose and how the main ideas identified in the body support the overall argument.

Persuasive speech outline

One of the best ways to prepare a great persuasive speech is by using an outline. When structuring an outline, include an introduction, body, and conclusion:

Introduction

Attention Grabbers

Ask a question that allows the audience to respond in a non-verbal way; ask a rhetorical question that makes the audience think of the topic without requiring a response.

Incorporate a well-known quote that introduces the topic. Using the words of a celebrated individual gives credibility and authority to the information in the speech.

Offer a startling statement or information about the topic, typically done using data or statistics.

Provide a brief anecdote or story that relates to the topic.

Starting a speech with a humorous statement often makes the audience more comfortable with the speaker.

Provide information on how the selected topic may impact the audience .

Include any background information pertinent to the topic that the audience needs to know to understand the speech in its entirety.

Give the thesis statement in connection to the main topic and identify the main ideas that will help accomplish the central purpose.

Identify evidence

Summarize its meaning

Explain how it helps prove the support/main claim

Evidence 3 (Continue as needed)

Support 3 (Continue as needed)

Restate thesis

Review main supports

Concluding statement

Give the audience a call to action to do something specific.

Identify the overall importan ce of the topic and position.

Persuasive speech topics

54 Problems to Avoid with Specific Purpose and Central Idea Statements

Learning objectives.

After reading this chapter, the student will be able to:

• Distinguish between the specific purpose, central idea, and main points of a speech;
• Differentiate between a speech to inform, persuade, and inspire or entertain;
• Write a specific purpose statement;
• Write a thesis or central idea statement;
• Distinguish between acceptable and unacceptable specific purpose and central idea statements;
• Compose appropriate specific purpose and central idea statements for informative, persuasive, and inspirational/entertaining speeches.

Problems to Avoid with Specific Purpose and Central Idea Statements

The first problem many students have in writing their specific purpose statement has already been mentioned: specific purpose statements sometimes try to cover far too much and are too broad. For example:

To explain to my classmates the history of ballet.

Aside from the fact that this subject may be difficult for everyone in your audience to relate to, it is enough for a three-hour lecture, maybe even a whole course. You will probably find that your first attempt at a specific purpose statement will need refining. These examples are much more specific and much more manageable given the limited amount of time you will have.

To explain to my classmates how ballet came to be performed and studied in the U.S.

To explain to my classmates the difference between Russian and French ballet.

To explain to my classmates how ballet originated as an art form in the Renaissance.

To explain to my classmates the origin of the ballet dancers’ clothing.

The second problem with specific purpose statements is the opposite of being too broad, in that some specific purposes statements are so focused that they might only be appropriate for people who are already extremely interested in the topic or experts in a field:

To inform my classmates of the life cycle of a new species of lima bean (botanists, agriculturalists).

To inform my classmates about the Yellow 5 ingredient in Mountain Dew (chemists, nutritionists).

To persuade my classmates that JIF Peanut Butter is better than Peter Pan. (organizational chefs in large institutions)

The third problem happens when the “communication verb” in the specific purpose does not match the content; for example, persuasive content is paired with “to inform” or “to explain.” If you resort to the word “why” in the thesis, it is probably persuasive.

To inform my audience why capital punishment is unconstitutional. (This cannot be informative since it is taking a side)

To persuade my audience about the three types of individual retirement accounts. (This is not persuading the audience of anything, just informing)

To inform my classmates that Universal Studios is a better theme park than Six Flags over Georgia. (This is clearly an opinion, hence persuasive)

The fourth problem exists when the content part of the specific purpose statement has two parts and thus uses “and.” A good speech follows the KISS rule—Keep It Simple, Speaker. One specific purpose is enough. These examples cover two different topics.

To explain to my audience how to swing a golf club and choose the best golf shoes.

To persuade my classmates to be involved in the Special Olympics and vote to fund better classes for the intellectually disabled.

To fix this problem, you will need to select one of the topics in these examples and speak on just that:

To explain to my audience how to swing a golf club.

To explain to my audience how to choose the best golf shoes.

Of course, the value of this topic depends on your audience and our own experience as a golfer.

The fifth problem with both specific purpose and central idea statements is related to formatting. There are some general guidelines that need to be followed in terms of how you write out these elements of your speech:

• Do not write either statement as a question.
• Always use complete sentences for central idea statements and infinitive phrases (that is, “to …..”) for the specific purpose statement.
• Only use concrete language (“I admire Beyoncé for being a talented performer and businesswoman”), and avoid subjective terms (“My speech is about why I think Beyoncé is the bomb”) or jargon and acronyms (“PLA is better than CBE for adult learners.”)

Finally, the sixth problem occurs when the speech just gets off track of the specific purpose statement, in that it starts well but veers in another direction. This problem relates to the challenge of developing coherent main points, what might be called “the Roman numeral points” of the speech. The specific purpose usually determines the main points and the relevant structure. For example, if the specific purpose is:

To inform my classmates of the five stages of grief as described by Elizabeth Kubler-Ross.

There is no place in this speech for a biography of Dr. Kubler-Ross, arguments against this model of grief, therapies for those undergoing grief, or steps for the audience to take to get counseling. All of those are different specific purposes. The main points would have to be the five stages, in order, as Dr. Kubler-Ross defined them.

There are also problems to avoid in writing the central idea statement. As mentioned above, remember that:

• The specific purpose and central idea statements are not the same thing, although they are related.
• The central idea statement should be clear and not complicated or wordy; it should “stand out” to the audience. As you practice delivery, you should emphasize it with your voice.
• getting the audience’s attention,
• revealing the topic,
• revealing the main points (i.e. your central idea),
• establishing your credibility, and
• establishing rapport with your audience.

One last word. You will notice that we have said nothing about titles of your speeches so far. A title is a good thing and serves purposes. Your instructor may or may not emphasize the title of your speech. This textbook chooses to focus on the purpose and central idea as the basis, even the spine of the speech. A good source on titles can be found here: Asbury, C. (2006-2018). How to write good speech titles. Retrieved from https://www.best-speech-topics.com/speech-titles.html

Case Studies in Specific Purposes and Central Idea Statements

Case Study One : Mitchell is taking a Fundamentals of Speech course in his second year of college. As a member of the college’s tennis team, he wants to speak on his favorite subject, tennis. He is assigned an informative speech that should be seven minutes long and use four external sources (other than his own experience). He realizes off the bat that he knows a great deal about the subject as far as how to play and be good at it, but not much about the history or origins or the international impact of the sport. He brainstorms a list of topics, as his instructor tells him to: 1. Famous tennis players 2. Rules of tennis 3. How to start playing tennis 4. How to buy or choose equipment for tennis 5. Why tennis is a great sport 6. Tennis organizations 7. Where tennis came from 8. Dealing with tennis injuries 9. Tennis and the Olympics 10. Famous tennis tournaments—grand slam events

However, he also wants to be sure that his audience is not bored or confused. His instructor gives him a chance to get in a small group and have four of his classmates give him some ideas about the topics. He finds out no one in his group has ever played tennis but they do have questions. He knows that everyone in his class is 18-24 years old, single, no children, enrolled in college, and all have part-time jobs.

Critique Mitch’s brainstorm topics based on what you know. What should he do? Can you come up with a good starting specific purpose?

Case Study Two : Bonita is required to give a 5- to 6-minute presentation as part of a job interview. The interview is for a position as public relations and social media director of a nonprofit organization that focuses on nutrition in a five-county region near her home. There will be five people in her audience: the president of the organization, two board members, the office manager (who is also the Human Resources director), and a volunteer. She has never met these people. Bonita has a college degree in public relations, so she knows her subject. She does as much research on the organization as she can and finds out about their use of social media and the Internet for publicity, marketing, and public relations. If does have a Facebook page but is not utilizing it well. It does not have any other social media accounts.

What would you suggest for Bonita? Here are some questions to consider. Should she be persuasive, informative, or inspiring? (General purpose). What should be her specific content area? How can she answer the two questions of the value of her topic to the audience and why would the audience think she is credible?

Possible Answer to Case Study One

Since Mitch’s purpose is informative, he should not do #5. Since his audience knows little about the sport, #1, #6, and #8 probably do not apply since the audience does not have a base of knowledge to build on. He will have to do research for the speech, so #7, #9, and #10 might work. Since he has so much experience compared to his audience, #2, #3, and #4 might also be good topics, and they are not entirely separated: you have to have equipment to play, and you have to know the rules to start playing.

Mitch decides to base his speech on this specific purpose statement: To explain to my classmates how they can begin to play tennis. Central Idea: Although it may look like a sport for accomplished athletes, you can begin to play tennis this weekend with some basic knowledge and equipment. (Preview) In this speech I will explain the equipment, the court, the play, and the scoring of a tennis game.

Possible Answer to Case Study Two

The stakes for this scenario are even higher than for Mitch. Bonita wants this position and wants to do a fantastic job on her interview and presentation. She decides to be informative in her general purpose. She knows she should mention some of her past projects in her speech as examples of her use of and knowledge about social media, and she knows the big question in her audience’s mind is “Will this candidate bring value and improvement to our communication processes?” At the same time, she does not want to come on too strong, so she decides to focus on how the three largest social media platforms of Twitter, Facebook, and Instagram could be used to enhance the organization. Also at the same time, she decides that 5 minutes is not long enough to use all three, so she decides to just discuss Twitter. Specific Purpose: To describe for the hiring panel how the nonprofit organization could use Twitter to fulfill its mission, especially since the organization already uses Facebook (although not well) but not Twitter. Central Idea: Twitter’s unique characteristics as a social media platform can contribute to the organization’s mission by reaching a wider audience, engaging younger audiences, and using visuals.

You should be aware that all aspects of your speech are constantly going to change as you move toward actually giving your speech. The exact wording of your central idea may change and you can experiment with different versions for effectiveness. However, your specific purpose statement should not change unless there is a really good reason, and in some cases, your instructor will either discourage that, forbid it, or expect to be notified. There are many aspects to consider in the seemingly simple task of writing a specific purpose statement and its companion the central idea statement. Writing good ones at the beginning will save you some trouble later in the speech preparation process.

Something to Think About

What if your informative speech has the specific purpose statement: To explain the biological and lifestyle cause of Type II diabetes. The assignment is a seven-minute speech, and when you practice it the first time, it is thirteen minutes long. Should you adjust the specific purpose statement? How?

Getting Started with Your Topic and Purpose

So far in this text we have examined many practical and theoretical aspects of public speaking as a method of communicating and as an art form. In this chapter we are going to get into the real meat of putting your speech together.

Often when we get to the point of sitting down to prepare a speech, we think about topics. That is understandable, but before we go any further, let’s recalibrate our minds to think also, or even more, about “purpose.” There are some benefits to considering purpose and topic simultaneously. Doing so will help you focus your speech to a manageable amount of content and become more audience-centered. Also, you will be able to make strategic decisions about other aspects of the speech, such as organization, supporting evidence, and visual aids.

Speeches have traditionally been seen to have one of three broad purposes: to inform, to persuade, and— Well, to be honest, different words are used for the third kind of speech purpose: to inspire, to amuse, to please, to delight, or to entertain. We will just use “to inspire” as the overall term here. These broad goals are commonly known as a speech’s general purpose , since, in general, you are trying to inform, persuade, or entertain/inspire your audience without regard to specifically what the topic will be. Perhaps you could think of them as appealing to the understanding of the audience (informative), the will or action (persuasive), and the emotion or pleasure.

Your instructor will most likely assign you an informative and a persuasive speech, and then perhaps one more. The third one might be a special occasion speech, such as a tribute (commemorative), an after-dinner speech, a toast, or a eulogy. These four types of speeches fit into the category of “to inspire” or “to entertain.” This text has sections on and examples of all three types.

It should be understood that these three purposes are not necessarily exclusive of the others. A speech designed to be persuasive can also be informative and entertaining, even if neither of those is the main purpose.

As we saw in Unit 1, the canons of rhetoric is the traditional way to explain the process of preparing a speech. That process is still a practical guide for today. The first canon, invention, or inventio , is discussed, at least in part, in this unit. Although in modern times we tend to think of invention as the creation of a new technology, invention basically means “discovery” of what to say.

The scholars of rhetoric from the ancient times encouraged the use of questions to “discover” the arguments and content of the speech. These were called “ topoi ” and there were a couple of dozen of them; modern scholars have reframed them as questions that can be used to develop reasons and material. These can be helpful in many ways, but here we will present just two basic questions you should consider for beginning your speech:

1. What value, connection, or interest does my purpose/topic have for the audience? What needs do they meet?

2. Why would the audience consider me, the speaker, a credible source on this purpose/topic?

We suggest that these two questions be in your mind as you develop your speech. You should answer them, directly or indirectly, for your audience in your speech. If your audience is unfamiliar with your topic, for instance, you would want to address the first one early in the speech. If your audience does not know anything about you, you should mention (in an appropriate way) your background in the subject area.

One of the authors has a core concept in her basic public speaking classes: The most effective speeches are the ones that answer the questions in the minds of the audience. She uses that to change the students’ focus from speaking just to express themselves to being audience-centered. She also uses the acronym “WIIFM.” This is not a new radio station, but the abbreviation for “What’s In It For Me?” The audience is asking this question, directly or indirectly, during a speech. Keep the WIIFM acronym in mind as you start to think about your speeches more and more from your audience’s perspective.

Formulating a Specific Purpose

Now that you know your general purpose (to inform, to persuade, or to entertain), you can start to move in the direction of the specific purpose. A specific purpose statement builds on your general purpose (such as to inform) and makes it more specific (as the name suggests). So if your first speech is an informative speech, your general purpose will be to inform your audience about a very specific realm of knowledge, for example, the history of NASA’s Shuttle program.

In writing your specific purpose statement, you will take three contributing elements that will come together to help you determine your specific purpose. The diagram shows those three elements. These three elements are you (your interests, your background, past jobs, experience, education, major), your audience (which you learned to analyze later), and the context or setting (also discussed later).

An old adage states, “Write about what you know.” In many ways, that is a great place to start with creating a speech, although you will need to consult other sources as well. If you start with ideas that reflect your interests, goals, and passions, that passion and commitment will come across in your speech, give you more credibility in the eyes of your audience, and make your speech more interesting.

This would be a good place for you to do an inventory. Retail stores do regular inventories to know what is “really there” in the stores. You have much more going on in your brain and background than you can be conscious of at any one time. Being asked the right kinds of prompts can help you find ideas. Below is a list of prompts for this inventory. To help generate some ideas for your speeches, complete the phrases and/or answer the questions below to see if any ideas can be generated from experiences or interests you may not have realized you had.

This inventory may seem long and intrusive, but digging a little deeper may help you find ideas and directions that are unique to you. You want to find this kind of subject matter and not the same topics others will gravitate towards just because they saw a list on Google on informative speech topics. Also, generating your list based on these questions and prompts will get you excited about your topic and talking about it to your classmates. For example, a very common persuasive speech topic is organ donation. There is nothing wrong with that topic per se and it is an important issue. However, if you ask yourself the right questions, you may come up with something far more central to who you are and that might interest and/or apply to the audience more.

Another approach that you might find helpful is to determine what you are passionate about through two binary routes. First, you will obviously be passionate about the things you love, so talk about those. Is The Simpsons your favorite TV show? Then you can inform us on the people and vision of the team behind this highly popular and long-running TV show. Do you feel that Big Brothers Big Sisters is a vital organization in the way it helps kids? Then persuade us to volunteer there. Conversely, you can also be passionate about things you don’t love (i.e., hate). Does it really annoy you when people don’t use their turn signals? Then persuade us to always use them. Do you want to scream when you hear a cell phone go off at the movies? Then persuade us that cell phones should be banned in theaters.

The Audience

Of course, what you love or hate may be in stark contrast to how your audience feels, so it is important to keep them in mind as well, which brings us to the next contributing factor. After you examine what you know and are passionate about, you have to determine if and how the topic has practical value or interest for others. It may be that it is a topic the audience is not immediately interested in but needs to know about for their own benefit. Then it becomes necessary for you to find that angle and approach that will help them see the benefit of the topic and listen to you. The more you know about your audience, the better you can achieve this goal. Good speakers are very knowledgeable about their audiences.

The Context

Many aspects come into the context of a speech, but the main ones are the time, place, and reason(s) for the event and the audience being there. Your classroom speeches have a fairly set context: time limits, the classroom, assignment specifications. Other speeches you will give in college (or in your career and personal life) will require you to think more deeply about the context just as you would the audience.

Putting It Together

Keeping these three inputs in mind, you can begin to write a specific purpose statement, which will be the foundation for everything you say in the speech and a guide for what you do not say. This formula will help you in putting together your specific purpose statement:

• Specific Communication (to inform, to explain, to demonstrate, to describe, to define, to persuade, to convince, to prove, to argue)
• Target Audience (my classmates, the members of the Social Work Club, my coworkers)
• The Content (how to bake brownies, that Macs are better than PCs)

Each of these parts of the specific purpose is important. The first two parts make sure you are clear on your purpose and know specifically who will be hearing your message. However, we will focus on the last part here.

The content part of the specific purposes statement must first be singular and focused, and the content must match the purpose. The word “and” really should not appear in the specific purpose statement since that would make it seem that you have two purposes and two topics. Obviously, the specific purpose statement’s content must be very narrowly defined and, well, specific. One mistake beginning speakers often make is to try to “cover” too much material. They tend to speak about the whole alphabet, A-Z on a subject, instead of just “T” or “L.” This comes from an emphasis on the topic more than the purpose, and from not keeping audience and context in mind. In other words, go deep (specific), not broad. Examples in this chapter will show what that means.

Second, the content must match the focus of the purpose word. A common error is to match an informative purpose with a persuasive content clause or phrase. For example,

To explain to my classmates why term life insurance is a better option than whole life insurance policies.

To inform my classmates about how the recent Supreme Court decision on police procedures during arrests is unconstitutional.

Sometimes it takes an unbiased second party to see where your content and purpose may not match.

Third, the specific purpose statement should be relevant to the audience. How does the purpose and its topic touch upon their lives, wallets, relationships, careers, etc.? It is also a good idea to keep in mind what you want the audience to walk away with or what you want them to know, to be able to do, to think, to act upon, or to respond to your topic—your ultimate outcome or result.

To revisit an earlier example, “to explain to my classmates the history of NASA” would be far too much material and the audience may be unsure of its relevance. A more specific one such as “to inform my classmates about the decline of the Shuttle program” would be more manageable and closer to their experience. It would also reference two well-known historical tragedies involving the Shuttle program, the Challenger Disaster in 1986 and the Columbia Explosion in 2003. Here are several examples of specific purposes statements. Notice how they meet the standards of being singular, focused, relevant, and consistent.

To inform my classmates of the origin of the hospice movement.

To describe to my coworkers the steps to apply for retirement.

To define for a group of new graduate students the term “academic freedom.”

To explain to the Lions Club members the problems faced by veterans of the wars in Iraq and Afghanistan.

To persuade the members of the Greek society to take the spring break trip to Daytona Beach.

To motivate my classmates to engage in the College’s study abroad program.

To convince my classroom audience that they need at least seven hours of sleep per night to do well in their studies.

Now that you understand the basic form and function of a specific purpose statement, let’s revisit the original diagram in this section. The same topic for a different audience will create a somewhat different specific purpose statement. Public speaking is not a “one-size-fits-all” proposition. Let’s take the subject of participating in the study abroad program. How would you change your approach if you were addressing first-semester freshmen instead of first-semester juniors? Or if you were speaking to high school students in one of the college’s feeder high schools? Or if you were asked to share your experiences with a local civic group that gave you a partial scholarship to participate in the program? You would have slightly different specific purpose statements although your experience and basic information are all the same.

For another example, let’s say that one of your family members has benefited from being in the Special Olympics and you have volunteered two years at the local event. You could give a tribute (commemorative speech) about the work of Special Olympics (with the purpose to inspire), an informative speech on the scope or history of the Special Olympics, or a persuasive speech on why audience members should volunteer at next year’s event. “Special Olympics” is a key word in every specific purpose, but the statements would otherwise be different.

Despite all the information given about specific purpose statements so far, the next thing you read will seem strange: Never start your speech by saying your specific purpose to the audience. In a sense, it is just for you and the instructor. For you, it’s like a note you might tack on the mirror or refrigerator to keep you on track. For the instructor, it’s a way for him or her to know you are accomplishing both the assignment and what you set out to do. Avoid the temptation to default to saying it at the beginning of your speech. It will seem awkward and repetitive.

Formulating a Central Idea Statement

While you will not actually say your specific purpose statement during your speech, you will need to clearly state what your focus and main points are going to be (preferably after using an introductory method such as those described in Chapter 8). The statement that reveals your main points is commonly known as the central idea statement (or just the central idea).

Now, at this point we need to make a point about terminology. Your instructor may call the central idea statement “the thesis” or “the thesis statement.” Your English composition instructor probably uses that term in your essay writing. Another instructor may call it the “main idea statement.” All of these are basically synonymous and you should not let the terms confuse you, but you should use the term your instructor uses.

That said, is the central idea statement the very same thing as the thesis sentence in an essay? Yes, in that both are letting the audience know without a doubt your topic, purpose, direction, angle and/or point of view. No, in that the rules for writing a “thesis” or central idea statement in a speech are not as strict as in an essay. For example, it is acceptable in a speech to announce the topic and purpose, although it is usually not the most artful or effective way to do it. You may say,

“In this speech I will try to motivate you to join me next month as a volunteer at the regional Special Olympics.”

That would be followed by a preview statement of what the speech’s arguments or reasons for participating will be, such as,

“You will see that it will benefit the community, the participants, and you individually.”

However, another approach is to “capsulize” the purpose, topic, approach, and preview in one succinct statement.

“Your involvement as a volunteer in next month’s regional Special Olympics will be a rewarding experience that will benefit the community, the participants, and you personally.”

This last version is really the better approach and most likely the one your instructor will prefer.

So, you don’t want to just repeat your specific purpose in the central idea statement, but you do want to provide complete information. Also, unlike the formal thesis of your English essays, the central idea statement in a speech can and should use personal language (I, me, we, us, you, your, etc.) and should attempt to be attention-getting and audience-focused. And importantly, just like a formal thesis sentence, it must be a complete, grammatical sentence.

The point of your central idea statement in terms of your audience is to reveal and clarify the ideas or assertions you will be addressing in your speech, more commonly known as your main points, to fulfill your specific purpose. However, as you are processing your ideas and approach, you may still be working on them. Sometimes those main points will not be clear to you immediately. As much as we would like these writing processes to be straightforward, sometimes we find that we have to revise our original approach. This is why preparing a speech the night before you are giving it is a really, really bad idea. You need lots of time for the preparation and then the practice.

Sometimes you will hear the writing process referred to as “iterative.” This word means, among other things, that a speech or document is not always written in the same order as the audience finally experiences it. You may have noticed that we have not said anything about the introduction of your speech yet. Even though that is the first thing the audience hears, it may be one of the last parts you actually compose. It is best to consider your speech flexible as you work on it, and to be willing to edit and revise. If your instructor asks you to turn the outline in before the speech, you should be clear on how much you can revise after that. Otherwise, it helps to know that you can keep editing your speech until you deliver it, especially while you practice. Here are some examples of pairs of specific purpose statements and central idea statements. 

Specific Purpose: To explain to my classmates the effects of losing a pet on the elderly.

Central Idea: When elderly persons lose their animal companions, they can experience serious psychological, emotional, and physical effects.

Specific Purpose: To demonstrate to my audience the correct method for cleaning a computer keyboard.

Central Idea: Your computer keyboard needs regular cleaning to function well, and you can achieve that in four easy steps.

Specific Purpose: To persuade my political science class that labor unions are no longer a vital political force in the U.S.

Central Idea: Although for decades in the twentieth-century labor unions influenced local and national elections, in this speech I will point to how their influence has declined in the last thirty years.

Specific Purpose: To motivate my audience to oppose the policy of drug testing welfare recipients.

Central Idea: Many voices are calling for welfare recipients to go through mandatory, regular drug testing, but this policy is unjust, impractical, and costly, and fair-minded Americans should actively oppose it.

Specific Purpose: To explain to my fellow civic club members why I admire Representative John Lewis.

Central Idea: John Lewis has my admiration for his sacrifices during the Civil Rights movement and his service to Georgia as a leader and U.S. Representative.

Specific Purpose: To describe how makeup is done for the TV show The Walking Dead.

Central Idea: The wildly popular zombie show The Walking Dead achieves incredibly scary and believable makeup effects, and in the next few minutes I will tell you who does it, what they use, and how they do it.

Notice that in all of the above examples that neither the specific purpose nor the central idea ever exceeds one sentence. You may divide your central idea and the preview of main points into two sentences or three sentences, depending on what your instructor directs. If your central idea consists of more than three sentences, then you probably are including too much information and taking up time that is needed for the body of the speech. Additionally, you will have a speech trying to do too much and that goes overtime.

Problems to Avoid with Specific Purpose and Central Idea Statements

The first problem many students have in writing their specific purpose statement has already been mentioned: specific purpose statements sometimes try to cover far too much and are too broad. For example:

To explain to my classmates the history of ballet.

Aside from the fact that this subject may be difficult for everyone in your audience to relate to, it is enough for a three-hour lecture, maybe even a whole course. You will probably find that your first attempt at a specific purpose statement will need refining. These examples are much more specific and much more manageable given the limited amount of time you will have.

To explain to my classmates how ballet came to be performed and studied in the U.S.

To explain to my classmates the difference between Russian and French ballet.

To explain to my classmates how ballet originated as an art form in the Renaissance.

To explain to my classmates the origin of the ballet dancers’ clothing.

The second problem with specific purpose statements is the opposite of being too broad, in that some specific purposes statements are so focused that they might only be appropriate for people who are already extremely interested in the topic or experts in a field:

To inform my classmates of the life cycle of a new species of lima bean (botanists, agriculturalists) To inform my classmates about the Yellow 5 ingredient in Mountain Dew (chemists, nutritionists) To persuade my classmates that JIF Peanut Butter is better than Peter Pan. (professional chefs in large institutions)

The third problem happens when the “communication verb” in the specific purpose does not match the content; for example, persuasive content is paired with “to inform” or “to explain.” If you resort to the word “why” in the thesis, it is probably persuasive.

To inform my audience why capital punishment is unconstitutional. (This cannot be informative since it is taking a side)

To persuade my audience about the three types of individual retirement accounts. (This is not persuading the audience of anything, just informing)

To inform my classmates that Universal Studios is a better theme park than Six Flags over Georgia. (This is clearly an opinion, hence persuasive)

The fourth problem exists when the content part of the specific purpose statement has two parts and thus uses “and.” A good speech follows the KISS rule—Keep It Simple, Speaker. One specific purpose is enough. These examples cover two different topics.

To explain to my audience how to swing a golf club and choose the best golf shoes.

To persuade my classmates to be involved in the Special Olympics and vote to fund better classes for the intellectually disabled.

To fix this problem, you will need to select one of the topics in these examples and speak on just that:

To explain to my audience how to swing a golf club.

To explain to my audience how to choose the best golf shoes.

Of course, the value of this topic depends on your audience’s interest in golf and your own experience as a golfer. The fifth problem with both specific purpose and central idea statements is related to formatting. There are some general guidelines that need to be followed in terms of how you write out these elements of your speech:

• Do not write either statement as a question.
• Always use complete sentences for central idea statements and infinitive phrases (that is, “to …..”) for the specific purpose statement.
• Only use concrete language (“I admire Beyoncé for being a talented performer and businesswoman”), and avoid subjective or slang terms (“My speech is about why I think Beyoncé is the bomb”) or jargon and acronyms (“PLA is better than CBE for adult learners.”)

Finally, the sixth problem occurs when the speech just gets off track of the specific purpose statement, in that it starts well but veers in another direction. This problem relates to the challenge of developing coherent main points, what might be called “the Roman numeral points” of the speech. The specific purpose usually determines the main points and the relevant structure. For example, if the specific purpose is:

To inform my classmates of the five stages of grief as described by Elizabeth Kubler-Ross.

There is no place in this speech for a biography of Dr. Kubler-Ross, arguments against this model of grief, therapies for those undergoing grief, or steps for the audience to take to get counseling. All of those are different specific purposes. The main points would have to be the five stages, in order, as Dr. Kubler-Ross defined them.

• There are also problems to avoid in writing the central idea statement. As mentioned above, remember that:
• The specific purpose and central idea statements are not the same thing, although they are related.
• The central idea statement should be clear and not complicated or wordy; it should “stand out” to the audience.
• As you practice delivery, you should emphasize it with your voice.
• Getting the audience's attention
• Revealing the topic
• Revealing the central idea and main points
• Establishing your credibility
• Establishing your rapport with the audience

One last word. You will notice that we have said nothing about titles of your speeches so far. A title is a good thing and serves purposes. Your instructor may or may not emphasize the title of your speech. This textbook chooses to focus on the purpose and central idea as the basis, even the spine of the speech. 

• Creating Speech Title with Impact

You should be aware that all aspects of your speech are constantly going to change as you move toward actually giving your speech. The exact wording of your central idea may change and you can experiment with different versions for effectiveness. However, your specific purpose statement should not change unless there is a really good reason, and in some cases, your instructor will either discourage that, forbid it, or expect to be notified. There are many aspects to consider in the seemingly simple task of writing a specific purpose statement and its companion, the central idea statement. Writing good ones at the beginning will save you some trouble later in the speech preparation process.

Case Studies

Case Study #1 

 Mitchell is taking a Fundamentals of Speech course in his second year of college. As a member of the college’s tennis team, he wants to speak on his favorite subject, tennis. He is assigned an informative speech that should be seven minutes long and use four external sources (other than his own experience). He realizes off the bat that he knows a great deal about the subject as far as how to play and be good at it, but not much about the history or origins or the international impact of the sport. He brainstorms a list of topics, as his instructor tells him to: 1. Famous tennis players 2. Rules of tennis 3. How to start playing tennis 4. How to buy or choose equipment for tennis 5. Why tennis is a great sport 6. Tennis organizations 7. Where tennis came from 8. Dealing with tennis injuries 9. Tennis and the Olympics 10. Famous tennis tournaments—grand slam events. 

However, he also wants to be sure that his audience is not bored or confused. His instructor gives him a chance to get in a small group and have four of his classmates give him some ideas about the topics. He finds out no one in his group has ever played tennis but they do have questions. He knows that everyone in his class is 18-24 years old, single, no children, enrolled in college, and all have part-time jobs.

Critique Mitch’s brainstormed topics based on what you know. What should he do? Can you come up with a good starting specific purpose?

Cast Study #2

Bonita is required to give a 5- to 6-minute presentation as part of a job interview. The interview is for a position as public relations and social media director of a nonprofit organization that focuses on nutrition in a five-county region near her home. There will be five people in her audience: the president of the organization, two board members, the office manager (who is also the Human Resources director), and a volunteer. She has never met these people. Bonita has a college degree in public relations, so she knows her subject. She does as much research on the organization as she can and finds out about their use of social media and the Internet for publicity, marketing, and public relations. It does have a Facebook page but is not utilizing it well. It does not have any other social media accounts.

What would you suggest for Bonita? Here are some questions to consider. Should she be persuasive, informative, or inspiring? (General purpose). What should be her specific content area? How can she answer the two important questions of the value of her topic to the audience and why would the audience think she is credible?

Something to Think About

What if your informative speech has the specific purpose statement: To explain the biological and lifestyle causes of Type II diabetes. The assignment is a seven-minute speech, and when you practice it the first time, it is thirteen minutes long. Should you adjust the specific purpose statement? How?
