Information Processing Techniques Program. Volume 1. Packet Speech Systems Technology

Abstract

The current program has two major thrusts; i.e., the development and refinement of practical low-cost, robust, narrowband and variable-rate speech algorithms and voice terminal structures, and the establishment of an experimental wideband satellite network to serve as a unique facility for the realistic investigation of voice/data networking strategies. This report covers work in the following areas: development of a custom-LSI-based narrowband channel vocoder; studies and real-time implementation of improved vocoder structures and algorithms; evaluation of speech processing capability of CCD- based spectrum analysis hardware; preparation of hardware and firmware for an upcoming speech algorithm test and evaluation program; design and implementation of packet voice terminals and local area access facilities; progress in satellite network and internetted packet voice conferencing and in the development of new packet voice network protocols; and design of a traffic emulation module for the wideband experimental network.
