Analysis of the Phoneme Recognition Performance of the Arm Continuous Speech Recognition System

Abstract

This memorandum presents the results of a phonetically motivated analysis of the speech recognition system developed as part of the ARM (Airborne Reconnaissance Mission) project. The aim of the work described here is to investigate to what extent errors can be explained by phonetic effects; those which cannot may indicate where models may be improved. The background to the investigation, and the problems of evaluating phoneme recognition performance are described, then the remainder of the report is concerned with a detailed analysis of specific types of errors, motivated by a desire to find phonetic explanations of them.
