Network Voice Conferencing. Speech Compression Research at CHI

Abstract

This report covers the activities of CHI in development of a network voice conferencing system using linear predictive coding for speech data compression from December 1975 through February 1976. The voice conferencing system is an extension of an existing network speech compression system incorporating control messages for speaker selection and data routing, together with transmitting and receiving programs which respond to them. The current implementation of this system at CHI is described. The system monitoring and recording facilities implemented are discussed with examples of their use for analysis of system performance.
