vt.physics on Instagram: "How a Robotic Mouth Mimics Human Speech! In 2011, researchers in Japan developed a robotic mouth designed not to simulate speech digitally, but to physically reproduce how humans generate sound. Instead of speakers and software, the device uses an air pump that functions like artificial lungs to push air through a synthetic larynx, where vibrating “vocal cords” create the initial sound. That airflow is then shaped by a silicone tongue, lips, and a controllable nasal cav
