Minimal Rate Digital Voice Transmission.
Abstract
In the report the recent developments of rate distortion theory are applied to the digital encoding methods for speech, with the emphasis on waveform encoding rather than on vocoders. The report is concerned with the broad class of digitized speech processors which are based on the principle of predictive encoding. The important contribution of the rate distortion analysis is the evaluation of the potential efficiency of a particular digital transmission structure. This is accomplished by the rigorous establishment of a lower bound on the digital transmission rate for a given distortion measure.
