Voice Switched Microphone Controlled Circuit Diagram

| |
Build a simple voice switched microphone controlled circuit diagram. Voice activated control apparatus selectively connects one of a plurality of microphones to an audio line and inhibits all other microphones from capturing the line while the initial connection is maintained. In this circuit an electronic microphone feeds a bandpass filter circuit (IC1A), then feeds a comparator, which in turn drives Ql. Ql is a switch that conducts when audio from IC1B causes Dl, C4, R6, and R7 to bias it ON.
