A Voice Recognizer for Car Telephone System 900249
A voice recognizer for automotive application which controls hands-free car telephone using voice has been developed. To ensure high recognition performance in noisy environments, a pitch synchronous analysis method and utterance detection method adaptable to noisy environments have been adapted to the voice recognizer.
A digital signal processor (DSP) for pitch synchronous spectrum analysis and a micro processor for pattern matching and controlling the system have been used as the main components, and the recognizer has been compactly designed for automobile use.
