| 中文摘要 |
本研究系探讨听觉障碍学生对不同说话者所说出的韵母的读话辨识情形，及读话所见的视素有无差异。受试为卅名就读台北市国民小学启聪班及资源教室的听觉障碍学生。本研究所用的研究工具为自编之「注音符号读话能力评量表韵母篇」，以十四个韵母（ㄝㄦ两音除外）和两个声母（ㄏㄋ）排列组合而成。所得资料以群落分析和单因子变异数分析进行处理。本研究的主要发现如下：1.受试只能将十四个韵母区分出一个视素：共包括九个韵母〔ㄜㄞㄟㄠㄡㄢㄣㄤㄥ〕。其它五个韵母〔ㄚㄛㄧㄨㄩ〕未能凝聚成视素。 2.不同说话者形成不同的视素。观看乙说话者所形成的视素中有十个韵母（包括ㄚ音）。3.视素中韵母凝聚的原因与其发音特性有关。4.韵母之平均读话正确率平均为47.54％，各个韵母读话正确率从77.50％到15.00％不等。观看ㄠㄡㄧㄨ四音的正确率最高，都在六成以上，但许多音的辨识率都未达半数，特别是ㄜ的正确率只达15％。 5.韵母视素读话正确率为84.03％。同一视素内的韵母易有视觉混淆的特性。.不同说话者导致的读话正确率有所不同。整体而言甲说话者最易于辨识，乙、丙说话者则无太大差异。但只有ㄞㄟㄠㄢㄣㄤㄧㄩ等音的得分有显著差异。

| 英文摘要 |
The purposes of this study were to explore the contents of vowel visemes lipread by elementary students with hearing impairment, and to examine whether talker differences existed by way of different visemes revealed. Subjects were thirty elementary students from four resource programs for the hearing-impaired in Taipei City. They were aE 6th graders. Nineteen of them were boys and eleven were girls. They were pre-lingual deaf with severe to profound hearing loss. Twenty-two of them had normal eyesight, while the other eight wore glasses. They lipread a set of 156 CV syllables and then wrote down what they thought they had seen. The syllables were formed by one consonant (either /n/ or /h/) plus one of the 14 Manderine vowels (with the exclusion of two vowels for articulatory reasons). These syllables were divided into three parts, and each part was spoken by one speaker. They were videotaped for the purpose of this study. Data were analyzed with Agglomerative hierarchical cluster analysis and ANOVA. The results were as follows: 1. Only one cluster was formed, with nine vowels involved. There were five vowels which failed to form a viseme. 2. Percentage of correct response for that cluster was high: 84.03%, while that for each consonant varied from 77.50% to 15.00%, with the average 47.54%. It also showed that most of the errors were located within the very cluster, which indicated that vowels within the cluster were highly confused. 3. There seemed to be no significant differences in viseme formed across three talkers; minute discrepancies, however, did emerge in two areas: (1) ten vowels were clustered by lipreading B speaker; and (2) scores of eight vowels showed significant differences.
