Abstract

The vowel sounds are perhaps the most interesting class of sound in English. Their importance to the classification and representation of written text is very low; however, most practical speech recognition systems rely heavily on vowel recognition to achieve high performance. In this paper we propose a technique for the vowel classification using Linear Prediction Coefficient with combination of statistical approach and Artificial Neural Network. The proposed technique achieves the 98. 7% accuracy rate for vowel classification.
