ABSTRACT
In this paper, we examined acoustic aspects of Bangla vowels for the purpose of the classification based on the experiments with Bangla disyllabic word pairs. This covered all the Bangla vowels for both male and female speakers in which the first vowel was preceded by a consonant having voiceless variant to avoid coarticulatory effect in the resultant study. We segmented vowels and applied time-domain and frequency-domain techniques to characterize their formant frequencies, bandwidths as well as fundamental frequencies along with the duration. We also applied different vowel normalization techniques for the classification and develop a Bangla vowel system that could be described in a triangular auditory space. The results provide data that can be used by researchers who require acoustic information about Bangla vowel production. It additionally presents the first large-scale analysis of Bangla vowels.
