Vocal Tract shape estimation of vowels C-V-V-C for diversified Indian English speakers

摘要

Human speech has hierarchical structure to have meaningful information. Speech is not a sequence of steady state sounds, abruptly changing from one to other. It consists of sentences, sentences can be divided in to words and words are constituted by phonemes which are the basic voice construction elements. We use language every day without devoting much thought to the process. But articulator movements i.e. the movement of lips, tongue and other organs- is among the subtlest and most adept of actions performed by human beings. In this paper vocal tract shape is estimated using LPC coefficients along with the combination of basic acoustic various speakers of different age, from each speaker with different vowels, consonants and different combinations. From the spectrogram we are extracting the formant frequency & all the considered test samples.
