Vowel Classification based on LPC and ANN

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.
