ABSTRACT
One of the best ways to improve our effectiveness as a speaker is to learn how to select and use supporting materials. Supporting materials are necessary to make our ideas clear or more persuasive to our listener. Although there are different lists of supporting materials, most experts in the speech field agree on these six: examples, explanation, statistics, testimony, comparison and contrast, and visual aids. When wisely chosen, the example is without a doubt the most effective and versatile of all the supporting devices. Examples can be brief or detailed, factual or hypothetical, and humorous or serious. The purpose of explanation is to make an idea clear or understandable. Visual aids increase understanding, engage the audience, and allow the speaker to cover topics or ideas that would be difficult to describe in words alone. Visual Aid Software is important that the speaker constructs the easiest and quickest display of digital images to make the visual display seamless to presentation.
