PURPOSE:To operate equipment with a human voice by amplifying only the electric signal of a voice for operation indication in the electric signal of a composite sound wave and judging what operation is indicated. CONSTITUTION:The electric signal component S2 of a sound wave generated by the equipment 12 itself which is equipped with an acoustic device is removed from the electric signal of the composite sound wave S1 composed of a sound wave generated by the equipment 12 equipped with the acoustic device and a sound wave of operation indication by a human voice and only the electric signal of the voice for operation indication is amplified and inputted to a rear stage A. Then a microcomputer 9 matches the operation indication which is converted into a digital signal with the features of operation indications stored in a storage means 11 to judge what operation is indicated and sends an instruction for the operation indication to an operating means 10 according to the judgement result. The operating means 10 performs operations corresponding to respective instructions for the equipment 12 equipped with the acoustic device according to the instructions of the microcomputer 9. Consequently, the equipment can be operated with the human voice. |
