Cepstral Analysis of Assamese Vowel Phonemes
Tapashi KashyapDas · 2013
Assamese is an Indo-Aryan family of languages, mainly spoken in the North-Eastern part of India and possesses its own unique identity. We carry out the cepstral analysis of Assamese vowel phonemes which is useful for accurate classification and identification of originality and gender of Assamese speaking informants. We create a small database for the Assamese vowels, spoken in isolation by 20 speakers with equal numbers of male and female speaker. Each spoken phoneme is repeated 10 times by each speaker. Thus, our database consists of 1600 phonemes. We use the linear prediction coding technique to compute the linear prediction cepstrum coefficients (LPCC), the weighted LPCC and the delta weighted LPCC for all the Assamese vowel phonemes of our database. These features are useful for Assamese speech recognition.
