Why is considering your audience at the center of the of the speech making process?

The audience is considered the center of the speechmaking process to gain their attention and spread the idea.

Explanation:

One needs an audience to deliver a good speech and the speaker shouldn't talk just about his theory. Because if the concept is heavy and if the talk just revolves around one's speech than he would lose the presence of the audience.

The speaker should respect the presence of his audience and understand where are their minds. And then gain the attention of his audience by going out of his talk a little bit and slowly try to make them understand the source of bis speech. If he delivers a speech not caring what the audience does then it would be like talking to a wall or oneself.
