DECREASING TIME DURATION OF RECORDED SPEECH ABSTRACT Disclosed is apparatus for and a method of decreasing the time duration of playback of recorded speech with- out distortion. Speech recorded at a normal rate is played back at a higher rate using two variable length buffers in alternating fashion to receive sampled speech segments. Threshold analysis logic circuitry is provided to continually compare the output voltage levels of both buffers and to switch the output between the buffers to a using device when the voltage level of both buffers is approximately zero and of an equal amplitude. In this way output to the using device con- sists of segments from both buffers joined with a minimum of generated noise and no associated dead zone without regard to any predetermined segment length.
