In the HT8656 record and play back voice IC there is a sound auto-detection circuit.When the circuit is in a wait state, the microphone receives a sound signal,and the circuit will automatically enter the recording state;when the sound stops (or be silent) about 1s, the circuit will automatically turn the recording state into playback state, and it will automatically return to the wait state after the end of the playback.It is used for voice-operated words learning toys, arts and crafts. Typical application circuit is shown as picture.
