Are all deaf people mute (or vice-versa)?
Not all deaf people are mute. My niece speaks very well and has been deaf since a child. But it takes a lot of training for a deaf person to learn to talk because if they have no reference for sound and they do not know how to form the sounds that make up the words. . A person that has gone deaf after they have learned to talk can speak very well because they learned the sounds they must make to be able to speak.
