This study was designed to investigate the articulatory tongue movements for the five Japanese vowels in normal subjects. Ultrasonography was used to three-dimensionally examine the tongue shape and position of the tongue tip in 30 healthy individuals (14 males and 16 females). The tongue shapes were classified into five types: convex type which forms a high-domed shape toward the palate (C type), flat type which shows a flat-shaped tongue (F type), groove type which forms a deep depression at the center of the tongue (G type), and intermediate shapes of these types (flat-convex type (FC) and flat-groove type (FG)). The position of the tongue tip was examined by comparing the tongue tip during vowel production with that in the rest position, and was classified into three positions: ‘anterior’ in which the tongue moved forward during articulation, ‘middle’ in which the tongue stayed in nearly the same position, and ‘posterior’.<br>As a result, frequent patterns were F type-posterior and FG typec-posterior for vowel /a/, G type-anterior for vowel /i/, G type-anterior for vowel /e/, and F type-posterior for vowel /o/. The patterns varied for vowel /u/ and the tongue movements of subjects who did not show these specific patterns. C type was not seen for any vowel by any subject. Also, an intersubject analysis of tongue movement patterns revealed that very few subjects showed agreement for all five vowels.<br>These results reveal the complexity of tongue movement during production of the five vowels in normal subjects.
