Public speaking (also called oratory or oration) is the process or act of performing a good speech to a live audience. This type of speech is deliberately structured with three general purposes: to inform, to persuade and to entertain. Public speaking is seen traditionally as part of the art of persuasion. Public speaking is commonly understood as formal, face-to-face speaking of a single person to a group of listeners. Public speaking can be governed by different rules and structures. For example, speeches about concepts do not necessarily have to be structured in any special way. However, there is a method behind giving it effectively. For this type of speech it would be good to describe that concept with examples that can relate to the audiences life.
