Solid State Audio/Speech Processor Analysis.

Abstract

This report details the progress made in evaluating the feasibility of applying Charge Coupled Devices (CCD's) and microprocessors to reduce the cost and complexity of Automatic Speech Recognition (ASR) systems. The report answers two basic questions. First, can CCD devices be used to generate speech recognition parameters that are useful for accurate low cost speech recognition? Second, what would be the cost and complexity for a realtime Automatic Word Recognition (AWR) system, using a CCD speech analyzer and current microprocessor technology? Experiments were conducted to measure the speed versus accuracy tradeoffs of four speed-up techniques. The techniques were demonstrated to be worthwhile in an efficient realtime AWR system. Finally, microprocessor architectures were designed to implement the realtime AWR system and then evaluated in terms of cost and complexity using three different microprocessors: the 8-bit Intel 8085A, the 16-bit Motorola MC68000, and a 16-bit configuration of the AMD 2901A.
