Abstract

PURPOSE:To cut off the sound source, etc., of an apparatus to be controlled until a word for voice remote control has been inputted, by outputting the output of an FF circuit as a muting signal and by generating an output for a certain period after the end of this muting signal. CONSTITUTION:Voice information transmitted from voice transmitter 11 is detected 15 and then waveform-shaped 16 and circuit 16 outputs ''1'' only when the voice input signal is inputted and ''0'' in the other period. Part of the output is differentiated 19 and supplied to the set input terminal of FF20. Then, the remainder is supplied to clear input terminal R of FF20 via inverter 21. The output of this counter 22 is differentiated 25 and supplied to reset terminal R of FF20. The output of FF20 is outputted as a muting signal for a certain period after the input signal is inputted. Then, the sound source, etc., of an apparatus to be controlled can be cut off until a word for voice remote control has been inputted.
