The system is based on the core processor chip ATMEGA16L, mainly WTR-S4 voice chip, using 4X4 keyboard input command control voice chip, using the microphone recording, set the sampling frequency, while using the speaker output sound. This design achieved through seven kinds 4X4 keyboard control commands, enabling recording, playback, select the playback sections, select the number of segments recording, adjust the volume, etc. functions, together constitute a system with a versatile voice.
