The thesis appears in the introduction of the speech so that the
audience immediately realizes the speaker's topic and goal. Whatever
the topic may be, you should attempt to create a clear, focused thesis
statement that stands out and could be repeated by every member of
your audience. It is important to refer to the audience in the thesis
statement; when you look back at the thesis for direction, or when the
audience hears the thesis, it should be clear that the most important
goal of your speech is to inform the audience about your topic. While
the focus and pressure will be on you as a speaker, you should always
remember that the audience is the reason for presenting a public
speech.
Avoid being too trivial or basic for the average audience
member. At the same time, avoid being too technical for the average
audience member. Be sure to use specific, concrete terms that clearly
establish the focus of your speech.
