Simple Physical Models of the Vocal Tract for Education in Speech Science

Takayuki Arai

Sophia University, Japan

In the speech-related field, physical models of the vocal tract are effective tools for education in acoustics. Araiís cylinder-type models are based on Chiba and Kajiyamaís 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 Fantís and Araiís three-tube models.
