Why should communicators take an audience-centered approach to communication?

Developing a rapport with the audience is seen as a vital
component in any communication, especially more so with public speaking.  In taking an
audience- centered approach to communication, there is a greater chance of being able to
connect with the audience if they are taken into account by the presenter.  I think that
this becomes important because it ensures that the audience and presenter are convergent
in emphasizing message and shared communication.  There is less of a chance for
divergence, restlessness, and disengagement to happen if communicators take their
audience into account.  In the end, communication is only possible when one side
validates the other.  This is done through assuming an audience- centered approach in
public speaking and all communication.  When the audience is validated, the speaker/
communicator will receive validation in the form of the message being
validated.
