Vowel Formant Bandwidths and Synthetic Vowels

This letter summarizes previous paper by the author on the determination of vowel formant bandwidth from decay patterns of vowel cavities. Formant bandwidth, as well as frequency of formant, depends on the open or closed condition of the glottis. The tuning of the resonator cavities changes, therefore, during each vibration period within the natural intonation. This occurrence can play a part in constructing of the synthetic vowel.
