[[alternative]]The performance of articulation and oral diadochokinetic rates of elementary-school children with visual impairment.

[[abstract]]本研究以26名就讀臺北市、新竹縣市、臺中市國小視障資源班、臺中啟明、惠明盲校國小的視覺障礙學童為研究對象，再以就讀同校或鄰近學校的同年級同性別的明眼學童26名為對照組，探討視覺障礙學童構音及口腔輪替速率的表現。研究結果發現在構音的子音正確率部分，明眼學童組的子音正確率表現，較視覺障礙學童組佳，有達顯著差異，全盲與弱視學童組則沒有顯著差異。構音的異常發生率部分，明眼學童組與視覺障礙組間無顯著差異，全盲與弱視學童組間無顯著差異。構音錯誤類型部分，視覺障礙組在捲舌音化、歪曲、ㄤ被ㄢ替代，這三項類型上與明眼學童組達到顯著差異，視覺障礙組構音錯誤類型依發生率排序，分別為：替代72.67％；其他10.22％；歪曲6.81％；省略2.27％；添加1.13％；不捲舌音化23.86％；邊音化15.90％；捲舌音化13.63％；同化6.81％；擦音塞擦音化5.68％。依注音符號難易度排序則為：ㄕㄓㄔㄖㄗㄙㄤㄘㄒㄈㄉㄊㄑㄢㄥ，ㄕ音錯誤總人次數最多。口腔輪替速率部分，明眼學童組口腔輪替速率範圍在4.87音節/秒至5.33音節/秒；視覺障礙學童組則在4.78音節/秒至4.85音節/秒。視覺障礙組的口腔輪替速率較明眼學童組慢，不過在統計上是未達顯著差異。全盲與弱視學童組間無顯著差異。口腔輪替速率無法預測構音的子音正確率及構音異常發生率。最後在構音錯誤總人次數上，視覺障礙組高於明眼學童組，且統計上有達顯著差異，全盲與弱視學童組間則無顯著差異。[[abstract]]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
