ABSTRACT:
A voice recognition system which controls industrial equipment or machinery. A proximity detector is attached to automatically adjust microphone sensitivity and to control automatic shutdown when the machine operator is not present. An enhanced barge-in feature uses a data switch that includes an input audio delay storage. The delay storage prevents loss of initial input data by delaying the input until the data switch switches from output to input modes. A variety of audio/video responses are provided to vary output and enhance attention span. Rules based input data handling provides a flexible response to user input.
