| Outline of Final Research Achievements |
Figure models of tongue were developed using viscoelastic materials. Extrinsic (Genioglossus anterior and posterior, Styloglossus, Hyoglossus and Palatoglossus) and Intrinsic (Longitudialis linguae superior and inferior, Transversus and Verticalis linguaes) tongue muscles are modeled. Coloring for realistic models was done using pigment and painting ink. Using pseudo muscles developed by rubber bands and nylon threads, simulations of tongue shaping during speech articulations were done.
As tongue shape and motion data for designing and evaluating models, tongue shape and motion were measured using a magnetic field position tracking device and a magnetic resonance imaging device.
The results have been contributed to speech science and education.
