The result of an investigation of the intelligibility of a hemiglossectomized patient with tongue cancer revealed that the lowest intelligibility level (13%) was estimated for /t/sound and the highest (100%) was estimated for /s/ sound of all phonemes produced using the anterior part of the tongue. The correlation of compensatory movement for /t/ and /s/ were then analyzed utilizing synchronous high-speed 16 mm cinematography and dynamic palatography. The results were summarized as follows: 1) The plosion to produce /t/ was produced by both lips and palatolingual contact in this case. 2) A fricative was made not only by palatolingual contact but also by a narrow space between both lips during utterance of /s/. Furthermore, the jaw movement seemed to support palatolingual contact. 3) It was suggested that the production of the compensatory articulation for a plosive sound was more difficult than for a fricative sound.
