| Summary: | 碩士 === 國立臺北護理健康大學 === 語言治療與聽力研究所 === 104 === In this study, 26 enrolled in Taipei, Hsinchu county, Taichung States overlooked barrier resource classes, visually impaired students as the research object, and then to attend the same school and the same grade school with same sex 26 children as control group . The purpore is to explore the visually impaired student’s articulation and oral diadochokinesis rate performance.
The results found that the articulation of percentage of consonants correct rate, sighted student’s performance have significant differences batter than visual impairment student. The articulation disorder rate that between the sighted student and visual impairment student that have no significant differences. Articulation error type part, visually impaired group in retroflexion and distortion and is ㄢ be substitute is the three types achieve significant differences between sighted students group, the visually impaired group’s articulation disorder types of errors sorted were: substitution is 72.67%; other is 10.22 ％; 6.81 ％ of the distortion; omission is 2.27%; addition is 1.13%; no retroflexion is 23.86%; 15.90% is the laterals; retroflexion is 13.63%; assimilation is 6.81%; fricative affrication is 5.68%.Phonetic symbols difficulty was: ㄕㄓㄔㄖㄗㄙㄤㄘㄒㄈㄉㄊㄑㄢㄥ. The ㄕis the most times of error number..Oral diadochokinetic rate portion, sighted children group diadochokinetic rate in the range of 4.87 syllables / sec to 5.33 syllables / sec; visually impaired children in the group of 4.78 syllables / sec to 4.85 syllables / second. The oral diadochokinetic rate visually impaired group than sighted children was slower, but less than statistically significant differences. Oral diadochokinetic rate can not predict t the articulation of percentage of consonants correct rate and articulation disorder rate. Finally, the articulation error total number of people, visually impaired group higher than sighted students group, and there are significant differences reached statistical.
All of the articulation of percentage of consonants correct rate, articulation disorder rate, Oral diadochokinetic rate, articulation error total number that have no significant differences between of the group of blind and partially.
