Public speaking is the art or practice of making a speech before an audience. In group or club events, there are many opportunities to make speeches. People who speak effectively are likely to become leaders. Training in effective public speaking is a key part of training for leadership in any field of activity.

Speakers who have a specific purpose and are successful in attaining it are said to be effective. If they try to inform, they are effective when the members of their audience understand the facts. If they try to persuade members of the audience to agree to do something or to change their opinions, the speakers are effective when members of the audience decide to take the action or when they do change their minds. If speakers try to entertain the audience, they are effective when the audience shows by applause or laughter that they are enjoying the speech.
