Public speaking, also called oratory or oration, has traditionally meant the act of speaking face to face to a live audience. Today it includes any form of speaking (formally and informally) to an audience, including pre-recorded speech delivered over great distance by means of technology.
Confucius, one of many scholars associated with public speaking, once taught that if a speech was considered to be a good speech, it would impact the individuals' lives whether they listened to it directly or not. His idea was that the words and actions of someone of power can influence the world.[1
