Abstract: An improved method and apparatus for digital speech storage and retrieval systems is described which disconnects the parallel tone receiver from the reception path of the hybrid circuit during the active playback of previously recorded material. 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.
