Computerized speech signal analysis circuit for voice-activated computer and other applications recognizes harmonics and phase synchronization effects generated by vocal tract

摘要

The computerized speech signal analysis circuit may recognize a particular voice. It may recognize a series of vocal commands for voice-activated computer and other applications recognizes harmonics and phase synchronization effects generated by vocal tract. It uses a source filter - driver response - model and performs a topological equivalent reconstruction of various acoustic modes of the human vocal tract.
