A very creative voice-activated light circuit diagram to prevent false triggering

The voice-controlled light is a voice-controlled electronic lighting device, which is composed of an audio amplifier, a frequency selection circuit, a delay opening circuit and a thyristor circuit. It provides a voice-controlled light that is easy to operate, flexible, has strong anti-interference ability and sensitive control. It uses the human mouth to emit a "hiss" control signal for about 1 second, so that the voice-controlled lighting device can be turned on and off conveniently and timely. It has an automatic delay shutdown function to prevent false triggering , and is equipped with a manual switch to make its application more convenient.

The circuit introduced in this question uses the MC14011 four-NAND gate integrated circuit to complete the automatic control of lighting. S unidirectional thyristor: PCR606JMC; It is composed of a voltage rectifier circuit, an amplitude detector circuit, a constant voltage source circuit, a delay opening circuit, a controllable delay switching circuit, and a thyristor circuit. The following is a circuit diagram of a rather creative voice-activated light .
