Development of a Time-Delay Speech Reconition System

Abstract -- State models, often used to model the dynamics of speech in recognition systems today, may not be flexible enough to model all important dynamic aspects of the speech. The present paper investigates an artificial neural network approach to the problem. An artificial neural network architecture is proposed and applied to some small memory problems and a word recognition task. The latter network has two explicit symbolic levels - phonemes and words - and both top-down and bottom-up strategies are learned by an automatic training algorithm.
