@aussiecarrot Most Deaf people do have the ability to speak, they just chose not to or haven't learned how. They learn by feeling the vibrations of a speaker's throat and mimicking those same vibrations.
As for the use of "dumb", we no longer use the word to refer to being mute for the same reasons we no longer call someone with a mental disability a "retard".
