Types of Supporting Material
There are several types of supporting material that you can pull from the sources you find during the research process to add to your speech. They include examples, explanations, statistics, analogies, testimony, and visual aids. You will want to have a balance of information, and you will want to include the material that is most relevant to your audience and is most likely to engage them. When determining relevance, utilize some of the strategies mentioned in Section 9.1 "Selecting and Narrowing a Topic". Thinking about who your audience is and what they know and would like to know will help you tailor your information. Also try to incorporate proxemic information, meaning information that is geographically relevant to your audience. For example, if delivering a speech about prison reform to an audience made up of Californians, citing statistics from North Carolina prisons would not be as proxemic as citing information from California prisons. The closer you can get the information to the audience, the better. I tell my students to make the information so relevant and proxemic that it is in our backyards, in the car with us on the way to school or work, and in the bed with us while we sleep.
