PURPOSE:To perform various control accurately only through the voice of crew by constructing such that a voice recognition circuit will perform predetermined operation only for predetermined time after provision of a standby voice command. CONSTITUTION:The voice command of crew provided within setting time set through a timer circuit 6 is fed from a microphone 1 for receiving the voice command through a gate 2 to a voice recognition circuit 3 thus to function specific actuator and to perform control in accordance with the voice command. Upon elapse of setting time of timer circuit 6, the gate 2 is brought to non-conductive state which will continue until a standby voice command is fed from a microphone 5 for receiving a standby command. Consequently, the noise in cabin is never provided from said microphone 1 to the voice recognition circuit 3. |
