ABSTRACT:
An input system for a voice recognizer circuit wherein a cue signal is issued to the user to indicate system readiness. A voice detector detects the presence of a voice signal. Control circuitry detects if a voice signal is detected prior to the end of the initial cue signal and, if so, causes a second cue signal to be issued, thereby preventing a loss of voice input. The voice detector can also be used to selectively switch an active one of a plurality of user channels to one of a smaller number of voice recognizers.
