In fact, many deaf mute have healthy vocal cords, the reason they can not talk is that they can not hear. This work is designed to help this kind of people. It consists of a dock, a part designed as people’s throat (I call it "Man-made Throat") and a touch screen. "Man-made Throat" can imitate the vibration of vocal cords. By feel and imitate the vibration of “Man-made Throat" could help the dumb learn how to talk. At the mean time, the mouth shape and sign language of the word or sentence will be shown on the screen help user learn easier.
