Analysis of the acoustics of hyper-nasality and also abnormal articulation of cleft palate patients

本研究为高鼻音相关的发音异常和腭裂患者的发音异常，我们从1999财年开始进行的研究，目的是利用CSL计算机系统和鼻音计对类似的声学指标进行分析，为改善高鼻音的声学评价和发音障碍提供指导。对第一财年购买CSL计算机系统建立的鼻音计与2000财年建立的具有更清晰的高鼻音的腭裂患者进行了针对传动连接(同步测量)的语音样本的测量。用掌握患者的正常成人和…正常人的正常嗓音，用拾取麦克风系统采集并分离出鼻音和口音的频率特性进行比较围绕腭裂手术的方法学，我们进行了检查，揭示了高鼻音的声学特征，结果是鼻音的发音强度呈现出明显的大值，出现了第二和第三共振峰频率下降的趋势。尤其是第三共振峰频率的下降趋势更明显。换言之，第三共振峰频率的下降强烈地参与了高鼻音的声学变化。此外，这一趋势在强劲的情况下也表现得非常明显。(声学鼻音++，鼻音评分60%或以上)与上鼻音、声学和鼻音加强一样，认为与正常成人鼻音评分相比，第三共振峰频率有下降和关系，在观察到声门停止的情况下，第二和第三共振峰频率的下降明显，与过去关于高鼻音和声门停止的关系的报道一致。此外，这项研究的要点在千叶市举行的第45届日本口腔颌面外科大会上公布。较少

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
