Speech and Communication
What is a speech? A speech is a “formal discourse in public”. “Almost any speech act is really the performance of several acts at once, distinguished by different aspects of the speaker's intention: there is the act of saying something, what one does in saying it, such as requesting or promising, and how one is trying to affect one's audience.” In general, a speech is the act of delivering a formal spoken communication to an audience.
A speech is a way of communication, which is distinct from other means of communication like conversations or small talks. To deliver a speech is to express a certain attitude, and the type of speech being performed corresponds to the type of attitude being expressed. For example, a statement expresses a belief, a request expresses a desire, and an apology expresses a regret. A speech usually intends to lay an effect on the listeners rather than simply being understood. When a president makes his inauguration speech, he is targeting on supports from the whole nation in his future work; when a general addresses his army, he is seeking the confidence and courage of his soldiers; when a leader of movement makes speeches to the public, he is expecting that more civilians will realize the social problems and fight for a better life through unremitting endeavor.
