项目摘要

Thc cxpcriments of discrimination and identification were carried out with proccssed Japanese vowels, explosive sounds and fricative sounds by using Sound Digital Filter <encircledR> and Sound Digital Spectro Editor <encircledR> targeting 15 cleft palate children (CP group) and 5 Functional articulation disorder children (FAD group). As the results that both in the experiment of identification of the vowels which formant were processed and in the experiment of discrimination of die sounds which imitated into glottal stop sound, the difference were not recognized between two groups. When the frequency distribution of fricative sounds were processed and made to distort gradually, cleft palate children judged the appropriate sounds in the amount of little distortion.The above expcriments were carried out before and after treatment toward articulation disorder and compared them. both in two groups, the differences were not recognized as either of the groups as well in the identilication ex … More periments of the vowels. Functional articulation disorder children showed that the discrimination ability turned good afier the treatment in die fricative sounds. and the difference from the cleft palate group stopped being recognized. All the differences weren't recognized though cleft palate children was classified by the degree of velopharyngeal competency and articulation disorder and compared.Clinical statistics about 70 patients with cleft lip and palate children following two-stage palatoplasty combined with Hotz's plate was assessed. The kind of articulation disorder which occurred after veloplasty were varied according to the degree of velopharyngeal incompetency until early' childhood about four years old. Glottal stop were occured in case of serious velopharyngeal incompetency, palatalized articulation occurred in case of slight one.From die above, the sound distinction ability in functional articulation disorder children was thought to be lower than cleft palate children. It was compared in cleft palate children, there were few factors that the abilities on sound distinction, occurrcnce factor of articulation disorder was thought velopharyngeal incompetency to influent greatly.Sonic clinical statistics were analyzed about lateral articulation and nasopharyngeal articulation which often occured in cleft palate patients and functional articulation disorder patients. Results suggested that the patients with lateral articulation as organic articulation disorder which is thinking about so far as the functional articulation disorder were contained. The occurrence cause of nasopharyugeal articulation in cleft palate patients was supposed that velopharyngeal incompetency was the most important factor. Less

采用Sound Digital Filter<encircledR>和Sound Digital Spectro Editor<encircledR>对15名腭裂儿童（CP组）和5名功能性构音障碍儿童（FAD组）进行了日语元音、爆破音和摩擦音的识别实验。结果表明，无论是对共振峰处理后的元音的识别实验，还是对模拟成声门塞音的母音的辨别实验，两组被试都没有识别出差异。当对摩擦音的频率分布进行处理并使其逐渐失真时，腭裂儿童在失真较小的情况下判断出合适的声音。在对构音障碍进行治疗前后进行上述实验并进行比较。在两组中，两组的差异都没有被识别出来， ...更多信息 vowel的用法功能性构音障碍儿童经治疗后对摩擦音的辨别能力有所提高。与腭裂组的差异不再被识别。对70例唇腭裂患儿行二期腭裂修复术联合Hotz板修复的临床资料进行统计分析。腭成形术后出现的语音障碍的类型根据腭咽功能不全的程度而不同，直到4岁左右的儿童早期。重度腭咽闭合不全患儿出现声门塞音，轻度腭咽闭合不全患儿出现腭化发音，提示功能性构音障碍患儿的辨音能力低于腭裂患儿。通过对腭裂患儿进行比较，认为语音识别能力、构音障碍的发生因素对腭裂患儿的构音能力影响较大，并对腭裂患儿和功能性构音障碍患儿常见的侧音和鼻咽音进行了临床统计分析。结果表明，目前认为的功能性构音障碍的器质性构音障碍患者均包含在内。腭裂患者出现鼻-咽-喉发音障碍的原因中，咽功能不全是最重要的因素。少
