| Abstract;This study introduces the "tagging MRI movie", a new method which combines the synchronized sampling method and tagging snapshot MRI. With this method, both the outer and inner configurations of the tongue during speech are visualized as a movie, and contraction of tongue-related muscles during speech can be estimated. Using data for /tata/ and /kaka/ produced by one Japanese-speaking male subject, we estimated that the superior longitudinalis and the anterior part of the genioglossus muscles synergically move the tongue-body antero-inferiorrly, and antagonically move the tongue-tip antero-superioly/postero-inferiorly. This new method can be used to acquire information with on the function of tongue muscles during speech, which is very important for clinical matters such as rehabilitation of dysarthria.
