Medical and Biological …, 1987

Abstract

Abstract A novel approach to low-cost microprocessor-based speech analysis and processing has been developed. Real-time Spanish vowel recognition accuracy of 98-76 per cent with an average time response of 200 ms in a noisy room is possible with very simple hardware and software. The voice-recognition method can be implemented in any commercially available 8-bit microprocessors. Also, the adjustment of the system to match other users vocal characteristics is easily performed. The voicerecognition system has ...
