TWO NEW SPEECH COMMUNICATION SYSTEMS

Abstract

Two unrelated speech communication systems are described which provide certain efficiencies in speech channel usage. One system achieves the equivalent of modest bandwidth compression by permitting two-to-one time multiplexing with simple terminal equipment and with a standard speech (telephone) channel. The other, based on extraction of equivalent amplitude, frequency, and phase modulating components of speech, may yield bandwidth compression comparable to that of a formant-tracking vocoder.
