ABSTRACT:
A voice-operated remote control system which transmits a remote control signal in response to a voice command has a detector for detecting whether a voice command is received or not. A detected signal from the detector is applied to a power supply control circuit. When there is no voice command received as detected by the detector, the power supply control circuit cuts off electric energy supplied to a speech recognition circuit which consumes the largest amount of electric energy in the voice-operated remote control system. The voice-operated remote control system also has a continuous operation instructing unit which produces an instruction signal that instructs a repetition command to cause a remotely controlled device to repeat an operation. The instruction signal is supplied to a continuous operation control unit which adds the repetition command to the remote control signal that is transmitted to the remotely controlled device.
