| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The lips have an important role in speech production system. The vocal-tract transfer functions are greatly influenced by the boundary conditions at the lips, and the directivity of the radiated speech is also affected by the shape of the lips and the head. For the improvement of the speech production model, this paper presents the results of acoustic simulation in the vicinity of the pseudo-lips by using FDTD method. A circular acoustic tube with wedge-shaped cut at the end of the tube is used as the pseudo-lips. The frequency characteristics of the radiated sound at the different positions in the vicinity of the pseudo-lips are computed. The computation results show the large differences in spectra depending on the observation positions. | |
