Simple physical models of the vocal tract for education in speech science

Takayuki Arai

In the speech-related field, physical models of the vocal tract are effective tools for education in acoustics. Arai’s cylinder-type models are based on Chiba and Kajiyama’s measurement of vocal-tract shapes. The models quickly and effectively demonstrate vowel production. In this study, we developed physical models with simplified shapes as educational tools to illustrate how vocal-tract shape accounts for differences among vowels. As a result, the five Japanese vowels were produced by tube-connected models, where several uniform tubes with different cross-sectional areas and lengths are connected as Fant’s and Arai’s three-tube models.
