Network Voice Transmission. Speech Compression Research at CHI

Abstract

A programmatically controlled analog switch unit for multiplexing several participants using a single vocoder into a network voice conference is described. Two methods of using this unit to support variations in conference protocols are discussed. An investigation was made of a proposed variable frame rate transmission system for network voice communication. This LPC-II system was compared with the existing system and several other possible choices. the comparisons are based on listening tests for quality and measured transmission rates.
