Study on development of voice and velopharyngeal competency in child

从腭咽能力发展的角度对唇腭裂儿童的声音共振进行了各种实验和调查，并进行了调整作为研究报告。内容如下：第一章研究了唇腭裂儿童婴儿期哭声的声学特征、鼻音平衡程度及其发育变化。在本研究之前，我们进行了一项试点调查，将用于调查的KAY公司的Nasometer对一名语言治疗师的听力判断结果与测量结果进行了比较。结果证明了该机器的有效性。在主要调查中，与唇裂患儿进行了对比检查，当腭咽功能不全包括早期影响哭泣声时，出生4个月后，可以清楚地表明，腭咽功能不全也开始影响喊出声。在第2260章中，为了在临床测试中获得所需的基准点，我们对使用鼻计获得的鼻平衡度进行了检查，并提取了数据。这个数据显示出来了。非腭裂患儿鼻平衡度明显低于无鼻音的唇腭裂患儿。因此，很明显，有必要使用非腭裂儿童的数据来建立一个基准点，并创建检查句，这也增加了一个地区的方言进行检查。第三章对70例唇腭裂患儿行2期腭裂成形术的腭咽功能长期观察结果进行了详细的阐述。腭成形术后腭咽功能的改善是经过长时间的观察发现的。它表明，一个功能不是在一种方法之后立即获得的，而是在开发中不断获得的。少

Various experiments and investigations were conducted from a viewpoint of development of velopharyngeal competency about the resonance of the voice of Cleft lip and palate children, and adjustment was performed as a research report. The contents are as follows.In Chapter 1,the acoustic feature of the crying sound of the babyhood stage of cleft lip and palate children, nasalance degree, and those development-change were investigated. In advance of this research, the pilot survey which compares the measurement result and the hearing judging of a speech therapist by Nasometer by KAY used for investigation was carried out. As a result, the validity of this machine was proved. In main investigation, comparison examination with cleft lip children was performed, and when velopharyngeal incompetency consisted of an early stage in affecting a crying sound, and four months after the birth, it was shown clearly that velopharyngeal competency begins to work also to shout utterance.In Chapter 2,260 … More non Cleft palate children which has normal nasal resonance in order to acquire a required fiducial point when using for a clinic test nasalance degree obtained using Nasometer was inspected, and data were extracted. This data was shown. As compared with cleft lip and palate children which does not have hypernasality in non Cleft palate children, nasalance degree showed the clear low value. Therefore, it became clear that it was necessary that the data of non Cleft palate children is used for a setup of a fiducial point and to create the inspection sentence which also added the dialect of an area to examination.In Chapter 3,the result of having observed velopharyngeal competency for a long period of time was explained in full detail about 70 Cleft lip and palate children which carried out 2stage palatoplasty. The improvement of velopharyngeal competency was found over the long period of time to 6 years old after palatoplasty operation. It was what shows that a function is not immediately obtained after a way but this continues being gained in development. Less
