Abstract
A method for data reduction in the transmission of speech signals is described, which is based on a new procedure for the extrapolation of short-time stationary signals. An example of the reconstruction network has been simulated on a minicomputer provided with an additional tape memory. Digital speech signals, stored in the tape memory, have been processed in the simulated system and restored and listened to in real time. This reconstructed sound is of very good quality compared with the original signal. In comparison with the Vocoder systems, very little hardware is required. Close similarity between the original and reconstructed speech signal has also been shown to exist in short-time analysis of the signals in both the time and frequency domains.
