Segmentation of Continuous Speech into Consonant and Vowel Units using Formant Frequencies

Abstract

This paper addresses the issues in segmentation of continuous speech into sub-word units of speech using Formants and support vector machines (SVMs). Many studies have been conducted to identify and discriminate vowels and consonants using acoustic/articulatory differences. In this study the continuous speech is segmented into smaller speech units and each unit is classified either consonant or vowel using the Formant frequencies. This process when further combined with recognition of each unit will form a complete speech recognition system. The proposed detection strategy is tested with the speech signals recorded from the television broadcast.
