Aristotle is one of the earliest models of communication, developed more than 2000 years ago. The model has five major elements of communication. These elements include the speaker, the message or the speech, the audience, the effect, and the occasion. Aristotle argued that every event should have a different speech with various effects. The model is widely applicable to public speaking. This model gives the speaker a central role in communication (Hartley & Bruckmann, 2002).
