Network Speech Systems Technology Program.

Abstract

This report documents work performed on the DCA-sponsored Network Speech Systems Technology Program. The areas of work are: (1) a switching and multiplexing study dealing with the analysis of buffered voice and data multiplexers and with a proposed technique for exploitation of speech activity detection to increase channel efficiency in a multi-link hybrid network; (2) a Demand-Assignment Multiple Access (DAMA) study focusing on prediction and buffering of digital speech streams for improved speech multiplexing performance on a broadcast satellite; (3) efforts in secure voice conferencing including protocol test and evaluation, support of the Secure Voice and Graphics Conferencing (SVGC) Test and Evaluation Program, and study of potential future-generation conferencing system strategies.
