Study of Sequential Estimation Methods for Speech Digitization.

Abstract

This report describes the results of a twelve month contract to study the application of sequential estimation methods to the problem of speech digitization. Bit rates of 8 Kbs to 16 Kbs, toll-quality transmission and simplicity of implementation were the main design objectives. Two basic systems were investigated. The first, referred to as a residual encoder, is a special form of ADPCM system which combines an adaptive predictor, adaptive quantizer and a source coder to achieve high levels of performance.
