| Research Abstract |
Purpose ;
The purpose of this study was to examine the characteristics of articulation of glossectomies of tongue.
Subjects ;
10 patients with oral cancer (7males, 3females) had a glossectomy.
Method ;
All patients was examined pre-operation, post-operation-1month, and 6months. the follows :
speech intelligibility(100syllales, conversation), tongue motor morality, the acoustic vowel space.
Conclusion ;
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.
Discussion ;
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.
