This research is abnormal articulation associated with hyper-nasality and it that are abnormal voice of the cleft palate patients the research that We are doing from the fiscal year 1999 for the purpose of that analyzes like acoustics by using CSL computer system and also Nasometer and make the guideline of the improvement of the evaluation and articulation disorders of the acoustics of hyper-nasality.We have done the picking, measuring of the voice sample targeting the cleft palate patients who is doing the gearing connetion (the synchronous measurement) between Nasometer of the purchase and lecture established of CSL computer system in the first fiscal year and have clearer hyper-nasality than the fiscal year 2000.Doing the comparison of the frequency characteristic of nasal voice and oral voice that were gathered and were separate the voice sample by using the microphone system of picking, Nasometer, by using the normal adult that is mastering the patients and also normal voice of a … More round the cleft palate operation for methodology, we did examination to announce the characteristic of hyper-nasality like acoustics.As a result, the utterance strength of nasal voice is showing a clearly big value with the trend that the second and the third formant frequency fall off was seen. Especially the trend was observed strongly with.The third formant frequency in other words it was suggested that the decline of the third formant frequency is getting involved in the change of the acoustics of hyper-nasality strongly. Also, the trend is seen strongly clearly in the strong case. (Acoustic Nasality ++, nasalance score 60% or more) like hyper-nasality to, acoustic and the reinforcement of nasal voice conceivabal that there are the decline and relation of the third formant frequency in comparison with a normal adult even nasalance score.The decline of the second and the third formant frequency are clearly even in the case that glottal stop is observed and agree with the report with regard to the relation of hyper-nasality and glottal stop in the past. Furthermore, the main point of this research announced in the 45th Japanese Oral and Maxillo-facial Surgery General Meeting in Chiba City. Less

这项研究是异常发音与高鼻音和它是腭裂患者的异常声音，我们正在做的研究，从财政年度1999年的目的，分析一样的声学使用CSL计算机系统，也Nasometer和作出的准则，改善评价和发音障碍的声学高鼻音。我们已经做了挑选，腭裂患者齿接时的语音样本测量在第一个财政年度建立CSL计算机系统的购买和讲座之间的Nasometer（同步测量），并有更清晰的超将采集的鼻音和分离的口语的频率特征进行比较，声音样本通过使用麦克风系统的采摘，鼻计，通过使用正常的成年人，是掌握病人和正常的声音， ...更多信息 方法学上，我们在腭裂手术前后进行了检测，揭示了腭裂患者的类鼻音的声学特征，结果显示，鼻音的发声强度明显增大，第二、第三共振峰频率有下降的趋势。尤其是第三共振峰频率，也就是说，第三共振峰频率的下降强烈地参与了超鼻音声学的变化。此外，在强的情况下，这种趋势非常明显。（鼻音++，鼻音评分60%或以上）如鼻音过重，结果表明，与正常成人平均鼻音评分相比，第三共振峰频率有明显的下降，并存在相关性。在声门塞音的情况下，第二、第三共振峰频率的下降是明显的，并与有关报道一致鼻音过强和声门塞音此外，在千叶市举行的第45届日本口腔颌面外科大会上公布了本研究的要点。少
