Abstract
We present the first experimental integrated-circuit vocal tract. The 275 muW analog vocal tract chip can be used for real-time speech production in bionic speech-prosthesis systems where low power is critical. We also describe how our vocal tract can be used with auditory processors in a feedback speech locked loop to implement speech recognition that is potentially robust in noise.
