Public speaking tips include organizing a speech into an introduction, main speech, and conclusion. The introduction should be brief but attention-grabbing using a quotation, example, definition, or humor. The main speech should have no more than three major points, each with a statement, elaboration, and examples to support it. Speakers should end clearly and thank the audience. Effective delivery involves maintaining eye contact, speaking at a natural pace, and practicing relaxation techniques to control nerves. Preparation, knowing the audience, and gaining experience are keys to confident public speaking.
