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 patternmatehing board involving a special purpose CMOS-processor capable of matehing with up to 1000 words in real time.A 80186 microprocessor, also contained on the pattern matehing board, provides control and data transfer between the speech recognition system and an arbitrary host computer.
