Are production controllerchecks the current state of receiving bufferand performs a reproduction process mentioned below. The data in receiving bufferis transferred to a decoderin accordance with instruction from reproduction controllerand decoded as voice sound, D/A converted by a D/A converterand then output as voice sound from a speaker.
