There are several types of mutes:
1. A
person who doesn't speak at all on purpose - "Elective Mute"
2. A
person who doesn't speak as a result of severe, if not complete deafness - "Deaf Mute"
3. A
person who doesn't speak at all in some situations, but is quite social in others - "Selective Mute"
4. A person who is legitimately unable to speak (or has very limited speech) due to a physical or mental health condition (usually brain damage) - This type of mutism does not have a name
