ABSTRACT:
An improved method and apparatus of digital speech storage and retrieval is described utilizing silence gaps for insertion of control signal information. This prevents interference with incoming control signals by feedback of signals through the hybrid circuit that occurs during playback of the stored speech. A diverter switch is controlled during the playback mode to allow incoming control signals to be decoded only when gaps of sufficient length are detected in the played back program.
