【摘要】：声调发音异常是听障儿童普遍存在的言语障碍表现之一。汉语是一种声调语言,声调与元音和辅音一样具有辨义的功能。声调异常极度影响了听障儿童的言语清晰度和可懂度,因此对听障儿童声调异常进行矫治是非常重要的。现有的研究主要以听障儿童声调感知为主,对于听障儿童的声调发音研究较少,仅有的一些研究也主要针对单字调发音。本研究选取了双字调中较为典型与复杂的三声双字调,运用声学分析的方法,探讨健听儿童与听障儿童三声双字调的不同组合形式及其变调的掌握能力。首先,本研究针对60名3到6岁的健听儿童的三声双字调进行了声学分析,获得了声学参数的参考范围,并讨论了健听儿童三声双字调的发音特征。获得了以下结论：(1)三声双字调变调难度等级由简到难以此是：“三声+四声”、“三声+二声”、“三声+一声”、“三声+三声”；(2)3岁与4岁儿童变调能力较5岁儿童较弱,4到5岁是儿童习得三声变调的关键时期。为后面的听障儿童三声双字调研究奠定了基础。其次,分析了37名3到6岁的听障儿童三声双字调的发音情况,获得了以下结论：(1)听障儿童三声变调能力显著弱于健听儿童；(2)听障儿童与健听儿童三声双字调模式基本相同,但其调值显著高于健听儿童,声调控制能力差。在上述实验的基础上提出了听障儿童三声双字调临床治疗建议：(1)加强巩固三声单字调的声调训练；(2)首先进行不产生变调的三声双字调组合的训练：“一声+三声”、“二声+三声”、“四声+三声”；(3)在进行三声双字调训练时遵循由简到难的原则,顺序为“三声+四声”、“三声+二声”、“三声+一声”、“三声+三声”。
[Abstract]:Dystone is one of the common speech disorders in children with hearing impairment. Chinese is a tone language, which has the same function as vowels and consonants. The abnormal tone affects the speech intelligibility and intelligibility of children with hearing impairment, so it is very important to correct the abnormal tone of children with hearing impairment. The existing studies mainly focus on the tone perception of children with hearing impairment, but there are few studies on tone pronunciation of children with hearing impairment, and only a few studies focus on tone pronunciation of single words. In this study, we select the typical and complex three-tone diatonic tone in the diatonic tone, and use the acoustic analysis method to explore the different combination forms of the three-tone diatonic tone and their ability to change the tone of the children with hearing impairment and hearing impairment. First of all, Based on the acoustic analysis of 60 children aged 3 to 6 years, the reference range of acoustic parameters is obtained, and the phonetic characteristics of the three tone and double tone of healthy hearing children are discussed. The following conclusions are obtained: (1) the difficulty of changing the tone from simple to difficult is: "three, four", "three, two", "three, one", The ability of children aged 3 and 4 to change their tones is weaker than that of children of 5 years old. 4 to 5 years old is the key period for children to acquire three tone changes. It lays a foundation for the study of the three tone and double tone of the children with hearing impairment. Secondly, the pronunciation of the three tones of 37 children with hearing impairment aged 3 to 6 years is analyzed. The following conclusions are obtained: (1) the ability of three-tone change of children with hearing impairment is significantly weaker than that of children with hearing impairment. (2) the two-tone mode of three sounds of children with hearing impairment is basically the same as that of children with hearing impairment, but its modulation value is significantly higher than that of children with hearing impairment. On the basis of the above experiments, the author puts forward the clinical advice on the treatment of three tones and two tones in children with hearing impairment. We suggest that we should strengthen the tone training for strengthening the tone training of three tone tones. Practice: "one sound three", "two sound three sound", "four sound three sound" 3) follow the principle from simple to difficult in the training of three sound and two tone, the order is "three sound and four sound", "three sound two sound", "three sound one sound", "three sound and four sound", "three sound two sound", "three sound one sound", "three sound".
