The purpose of this study was to examine the characteristics of articulation of glossectomies of tongue.
10 patients with oral cancer (7males, 3females) had a glossectomy.
All patients was examined pre-operation, post-operation-1month, and 6months. the follows :
speech intelligibility(100syllales, conversation), tongue motor morality, the acoustic vowel space.
1. The speech intelligibility was proved pre and post-operation.
2. The acoustic vowel space was changed by pre and post-operation.
3. The foundamentall and 2 was the nearer, the server of range of resection.
1. The acoustic vowel space was affected by the severity of tongue motor ability, and the speech intelligibility.
2. We can use the vowel space by the acoustic measures.
