Speech Compression and Synthesis

Abstract

This document reports progress in the development of a phonetic speech synthesis algorithm, implementation and development of a real-time LPC (Linear Predictive Coding) vocoder. Testing of spectral modeling using adaptive lattice methods, and results of a subjective evaluation of the mixed source excitation in LPC synthesis. A new diphone utterance data base has been designed and is being recorded for the phonetic synthesis program. Keywords include: Voice-excited coder and high-frequency regeneration.
