Magnetic Resonance Imaging (MRI) movie of the tongue motion was acquired for Japanese “a”, “ka”, and “ga” columns. We explain this method and a few problems the speech researchers use image processing tools. We tested more phoneme patterns, /aeiueoao/, /kakekikukekokako/ and /gagegigugegogago/. The “synchronized sampling method” was used for the acquisition of the speech, and the subjects repeated the same task by listening to the guide tones. (1) The images of the same phonemes were compared, and (2) The kymograph was made. The horizontal-direction corresponds to the time, and the vertical direction implies the distance to the soft palate and the speech organ. The kymograph showed different tendencies from the previous speech research. MRI artifact should be also taken into account carefully.
