This paper describes a speech recognition system for speaker dependent isolated word recognition. The system consists essentially of two processing boards: a feature extraction board using a TMS320C25 signal processor, and a pattern matching board involving a special purpose CMOS-processor capable of matching with up to 1000 words in real time. A 80186 microprocessor, also contained on the pattern matching board, provides control and data transfer between the speech recognition system and an arbitrary host computer.
