Effective public speaking requires preparation. The speaker should identify the purpose of the speech as either to inform, convince, or move the audience to action. It is important to create an outline, choose evidence and arguments, and give cues to guide the audience. Speakers should practice their speech several times, having friends provide feedback, and get comfortable with any visual aids. When presenting, make eye contact with the audience and draw on both reason and emotion to engage them. Conclude by summarizing key points and thanking the audience for their time and attention.
