Public speaking involves speaking to an audience to inform, influence, or entertain them. It commonly refers to face-to-face communication with a group intended to share knowledge or perspectives to achieve a purpose. Successful public speaking requires considering elements like the speaker, purpose, message, medium, setting, listener response, potential interferences, and consequences. An effective speech structure includes an attention-grabbing introduction, presentation of main points organized logically in the body, and a conclusion that restates the key themes.
