A special purpose CMOS signal processor for use in a speaker-dependent isolated word-recognition system is described. The recognition is performed on the basis of pattern matching, i.e. the processor calculates the distances between the spoken word to be recognised and all the reference words stored in a template memory by means of the dynamic-time-warp algorithm. Operating at 10 MHz, the processor performs recognition for a vocabulary of up to 1000 words.
