tlooto Summary

A vocoder technique is described in which speech signals are represented by their short-time phase and amplitude spectra, which leads to an economy in transmission bandwidth and to a means for time compression and expansion of speech signals.

Abstract

A vocoder technique is described in which speech signals are represented by their short-time phase and amplitude spectra. A complete transmission system utilizing this approach is simulated on a digital computer. The encoding method leads to an economy in transmission bandwidth and to a means for time compression and expansion of speech signals.
