Abstract
An electronic voice recognition system utilizes a microphone having noise-cancelling characteristics and a standardizer network to achieve further noise reduction and signal standardization over a range of input levels. The output of the standardizer is coupled to voice processor circuitry which provides a computer-compatable output corresponding to the voice information received. The system may be embodied in a multi-station environment in which the voice reception stations are coupled to a remote central processing location. A variety of processing techniques, including analog and digital, parallel and sequential, may be utilized to pass the voice signals to the processors. Upon successful processing, a confirmation signal is passed to the appropriate voice-originating station.
