Research output: Contribution to journalConference article


A VLSI chip is designed as an one chip solution for isolated speech recognition system. It is a integrated processor which detects endpoint, extracts feature vector from speech signal, and computes the spectral distances using a dynamic time warping technique. It is designed using a 0.8 μm CMOS technology including 66,760 gates, and runs with a 10MHz clock. The designed chip can recognize 1000 isolated words per second with an average recognition accuracy of 90.3%.
