Why Are There Mutes?

The voice is produced by the vibration of the vocal cords, ;instructed by the nerve of the cerebrum. When a person has

something wrong with his or her vocal cords or the nerve which controls speaking, he or she will become mute. Some children are mute because they had ear problems when they were born or they became deaf because of an illness when they were small. These children can not speak because they cannot hear the voices of other people. However, they can sometimes learn to sneak with the help of specially-train(-d teachers. They also use sign language and lip-reading to communicate.
