Abstract: A RECOGNITION SYSTEM composed (in addition to memory chips) of afiont-end chip for feature extraction, a pattern matching chip and a microprocessor for the final (low data rate) decision and control will be discussed. A TTL prototype of this sytem is presently in use to provide voice-input t o an IC layout system. interface between the microphone and the linear A/D, short-time spectrum analysis using a bank of bandpass filters, logarithmic compression and endpoint detection. These functions could either be re…
