HT8656 - Talking Back

Description

The HT8656 is a single chip CMOS LSI for talking back applications using an ADM algorithm.

Functions of the IC consist of recording/playing as well as auto power off.

It starts recording when a sound input is detected, and stops to play back when silence lasts 0.5 seconds during recording.
