Abstract

Acoustic space of Bangla Vowel based on articulatory properties of vocal tract plays a significant role in Bangla speech synthesis and recognition. A vowel system is essentially a way of dividing up the "vowel space" into distinct vowel phonemes. In general, languages make the most efficient use of the vowel space. This paper synthesizes vowel space illustration by graphically showing where a speech sound for Bangla language, such as a vowel, is located in both "acoustic" and "articulatory" space of the vocal tract tube. Measurements of the spectral characteristics and the formant frequencies were made for each vowel from isolated Bangla word spoken by both male and female speakers. All these measurements are tested in synthesis of isolated utterance.
