Command and Control Related Computer Technology. Part I. Packet Radio. Part 2. Speech Compression and Evaluation

Abstract

This document describes progress on (1) development of a packet radio network, (2) speech compression and evaluation. Activities reported under (1) includes work on Station Software and Internetworking Research and Development; and (2) development of a new source or excitation model for the synthesizer of the narrowband LPC vocoders, with the objective of enhancing the naturalness of the synthesized speech, development and validation of several procedures for objectively evaluating the quality of LPC vocoded speech.
