When the speaker looks so confident with presentation, the audience can beliefs and agrees with his/her idea. So, self-confident must have to be a good speaker. Second, the speaker should be a good characteristics, good personality, good posture and other. When the speaker look so nice, so that the audience can pay attention to the speaker. Third, the speaker can communicate with the audience about the topic that speaker present.
