1. Devi Harisandi discusses how to gain confidence speaking publicly by seeing the audience as equal or below you, being self-convinced of your abilities, and dominating the materials. 2. There are three main purposes of speech: to entertain, inform, or persuade. Persuasion can be to convince, reinforce an existing viewpoint, or call the audience to action. 3.
