Researchers at the Kagawa University in Japan have created a robotic mechanical mouth that uses a learning algorithm to mimic the sounds of human speech. Early prototypes did not have a nose or lips, but recent models are more complete.

Engineers Hideyuki Sawada, Mitsuki Kitani, and Yasumori Hayashi used artificial vocal cords in combination with other artificial voice-making parts to create the robotic mouth that is able to recreate and analyze human sounds and provide input that the hearing-impaired can use to improve their pronunciation and speech.
