ABSTRACT:
A system and technique for enabling voice activation of an audio transmission system includes circuitry for storing and delaying an audio input signal, which may include a voice signal, and computer analysis of the input signal to determine voice input in accordance with predetermined parameters. The computer analysis includes programmed sampling of the input signal in response to a plurality of adjustable criteria to enable the analysis to be tailored for a variety of environments while producing reliable voice activation. Upon detection of a voice signal on the input in response to the computer analysis, the previously-stored audio signal is provided as output to be transmitted by the transmission system. Computer control of the system is also utilized to provide unkeying of the transmission following termination of the voice signal.
