The general purpose of any speech will be either to Inform; Motivate/Persuade; or Entertain your audience. As soon as you know the general purpose of your speech you can develop your Specific Purpose Statement (What the speaker will accomplish). Your Specific Purpose Statement is used to develop your speech. You don't acutally say it in your speech.
Restrict your Specific Purpose to one idea only. In Speech 151 for the informative speech your general purpose is to inform. For an informative speech you will want to start your specific purpose statement with "I will inform my audience about...." A Specific Purpose Statement for an informative speech will be phrased much like the following statements. Click here for more examples of Specific Purposes, Central Ideas, and Main Points.
Informative speech specific purpose statements:
- I will inform my audience about the two major forms of hula.
- I will inform my audience about what lifegaurds do as part of their jobs.
When you have your specific purpose statement you are ready to compose your Thesis Statement/Central Idea (they are one in the same). This is the most important part of your speech. This is one sentence that encompasses the central idea of your speech.
Writing your thesis statement/central
idea is a four step process:
- Choose your topic
- Determine your general purpose
- Write your specific purpose statement
- Tie it all together by composing a clear concise thesis statement/central idea
"The two major forms of hula that have played an important role in Hawaiian history and have developed into unique dances are the Kahiko and 'Auana."
"Lifegaurding is a great way to spend your days on the beach, but the work includes training, teaching, and lots of practice making it more challenging than what you see on "Baywatch."
Your next step is to compose the main points of your speech. Main points are complete sentences that create a dialogue with your audience. With your main points you want to create questions in the mind of your audience. You will answer the question in your support of your main points. You make a claim in your main points and you support your claim in your subpoints, sub-subpoints, sub-sub-subpoints and so on.
The following are examples of Main points:
Specific Purpose: I will inform my audience about the two major forms of hula.
Central Idea: "The two major forms of hula that have played an important role in Hawaiian history and have developed into unique dances are the Kahiko and 'Auana."
- (Main Point 1) "The ancient hula or Kahiko is a unique form of hula."
- (Main Point 2) "The Kahiko plays an improtant role in the history of Hawaii."
- (Main Point 3) "The 'Auana or modern hula has played an important role in Hawaiian history."
- (Main Point 4) "The 'Auana has developed into a unique form of dance and storytelling."

Chapter 5: Presentation Organization
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] __________________. [The 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.
