| Outline of Final Research Achievements |
With the aim of elucidating the mechanism of speech production and its application to a speech robot, we designed and created 3DCG models of the speech-producing organs (maxilla, mandible, hyoid bone, tongue, lips, muscles attached to them, and their surrounding skin, vocal cords, vocal tract, and nasal cavity) using modeling software with reference to MRI measurement data. The models of the maxilla, mandible, and hyoid were made using a 3D printer that was installed in the laboratory. Models of the tongue, lips, vocal cords, and vocal tract were made by hand, and models of these speech organs were made using viscoelastic materials such as urethane gel. A model of the vocal tract was also made, which was driven by an electric laryngeal model to produce speech sounds. We also proposed a method to synthesize MRI images of the lungs, vocal cords, and vocal tract and display them in a moving image.
