Abstract
Vowel normalization is a procedure of finding out the intermediate parameter from varied forms of utterance produced by different speakers of a particular language or same vowel token uttered by same speaker at different times. Every speaker has their own speech parameters and the variation of these parameters is the primary cause of speaker to speaker variation of speech sounds. The significant parameters that distinguish one vowel from the other are its formant values. In this paper an automatic vowel recognition procedure is described where the eight standard Assamese vowels are analyzed through Formant detection and Normalization. Here a standard approach is adopted for Normalization of vowels based on two Formants F1 and F2. A Vowel Recognition System based on Formant Estimation is developed and a preliminary recognition test for isolated vowels shows an expected recognition rate of 84-96% for arbitrarily selected speakers.
