The source imagines, creates, and sends the message. In a public speaking situation, the source is the person giving the speech. He or she conveys the message by sharing new information with the audience. The speaker also conveys a message through his or her tone of voice, body language, and choice of clothing. The speaker begins by first determining the message—what to say and how to say it. The second step involves encoding the message by choosing just the right order or the perfect words to convey the intended meaning. The third step is to present or send the information to the receiver or audience. Finally, by watching for the audience’s reaction, the source perceives how well they received the message and responds with clarification or supporting information.
