| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | MRI is a powerful tool for the study of speech production. Although MRI sequences specifically designed for vocal tract imaging have been developed and everyone can use them, MRI-based speech production studies are small in number. One possible reason is that information about MRI characteristics relating to vocal tract imaging and data processing techniques is limited. In this paper, we provide a brief overview of MRI sequences used in this field, that is, the conventional sequence, phonation synchronized sequence, and movie sequence. Next, we review MRI data processing techniques for each sequence and outline the transmission line model and the finite-difference time-domain method as acoustic analysis methods. Finally, we comment on future prospects concerning MRI-based speech production studies. | |
