No, A speaker should not minimize his or her use of nonverbal communication.
A nonverbal communication is a mode of communication that uses body language, distance or physical appearance of voice or touch. So when a person is delivering a speech to an audience, he should use the nonverbal communication along with the verbal speech. That would increase the power in his words. It is said that a picture is worth a hundred words. So when a speaker is using the body language along with the words from his mouth, a complete picture is there for the audience. This will enhance his communication.
