At the exhibition Robotech in 2011, Professor Sawada of Japan’s Kagawa University, has demonstrated a robot that can reproduce facial expressions and real human speech. A similar result was achieved by artificially created elements, simulating the lungs, vocal cords and nasal cavity. All sounds created by normal air flow, produced under pressure through a control valve. The resonance tube in the form of holes, like a person’s mouth, has eight of the vocal cords, vocal tract and tongue made of silicone. For more information watch the video bellow.
