【摘要】:聲調(diào)發(fā)音異常是聽障兒童普遍存在的言語障礙表現(xiàn)之一。漢語是一種聲調(diào)語言,聲調(diào)與元音和輔音一樣具有辨義的功能。聲調(diào)異常極度影響了聽障兒童的言語清晰度和可懂度,因此對(duì)聽障兒童聲調(diào)異常進(jìn)行矯治是非常重要的,F(xiàn)有的研究主要以聽障兒童聲調(diào)感知為主,對(duì)于聽障兒童的聲調(diào)發(fā)音研究較少,僅有的一些研究也主要針對(duì)單字調(diào)發(fā)音。本研究選取了雙字調(diào)中較為典型與復(fù)雜的三聲雙字調(diào),運(yùn)用聲學(xué)分析的方法,探討健聽兒童與聽障兒童三聲雙字調(diào)的不同組合形式及其變調(diào)的掌握能力。 首先,本研究針對(duì)60名3到6歲的健聽兒童的三聲雙字調(diào)進(jìn)行了聲學(xué)分析,獲得了聲學(xué)參數(shù)的參考范圍,并討論了健聽兒童三聲雙字調(diào)的發(fā)音特征。獲得了以下結(jié)論:(1)三聲雙字調(diào)變調(diào)難度等級(jí)由簡(jiǎn)到難以此是:“三聲+四聲”、“三聲+二聲”、“三聲+一聲”、“三聲+三聲”;(2)3歲與4歲兒童變調(diào)能力較5歲兒童較弱,4到5歲是兒童習(xí)得三聲變調(diào)的關(guān)鍵時(shí)期。為后面的聽障兒童三聲雙字調(diào)研究奠定了基礎(chǔ)。 其次,分析了37名3到6歲的聽障兒童三聲雙字調(diào)的發(fā)音情況,獲得了以下結(jié)論:(1)聽障兒童三聲變調(diào)能力顯著弱于健聽兒童;(2)聽障兒童與健聽兒童三聲雙字調(diào)模式基本相同,但其調(diào)值顯著高于健聽兒童,聲調(diào)控制能力差。 在上述實(shí)驗(yàn)的基礎(chǔ)上提出了聽障兒童三聲雙字調(diào)臨床治療建議:(1)加強(qiáng)鞏固三聲單字調(diào)的聲調(diào)訓(xùn)練;(2)首先進(jìn)行不產(chǎn)生變調(diào)的三聲雙字調(diào)組合的訓(xùn)練:“一聲+三聲”、“二聲+三聲”、“四聲+三聲”;(3)在進(jìn)行三聲雙字調(diào)訓(xùn)練時(shí)遵循由簡(jiǎn)到難的原則,順序?yàn)椤叭?四聲”、“三聲+二聲”、“三聲+一聲”、“三聲+三聲”。
[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".
