Computer speech these days are mostly computer simulated or a series of prerecorded wave files. Researchers in Kagawa University in Japan however designed a robotic mouth to make sounds similar to the way humans do. Air is forced through tubes in its throat and sound is produced in a synthetic mouth, tongue and nasal cavity. A microphone listens to human speech and the robotic mouth tries to reproduce the same sounds on its own. The mouth goes through trial and error listening to its own output and revising the shape of the throat and mouth until it approximates the sound it is trying to reproduce. The video is a little creepy but shows a human looking rubber mouth and nose going through various shapes to reproduce sound and speech.
