【摘要】: 聲調發(fā)音異常是聽障兒童普遍存在的言語障礙的表現(xiàn)之一。漢語是聲調語言,聲調與元音、輔音一樣具有辨義功能。因此,對聽障兒童聲調異常的矯治非常重要。而現(xiàn)有的研究多以聽障兒童的聲調感知為主,對聽障兒童聲調發(fā)音的研究很少,并且在臨床上缺乏系統(tǒng)的治療策略。因此,本研究旨在通過聲學分析的方法,探討聽障兒童單音節(jié)詞聲調,即單字調發(fā)音的主要錯誤類型及其聲學特征,建立聲學參數(shù)參考范圍,進而提出系統(tǒng)的聲調異常治療框架和治療策略。 首先,本研究通過聲學分析的方法研究了60名3-6歲正常兒童四種單字調的基頻曲線和聲學參數(shù)參考范圍,了解正常兒童聲調發(fā)音的聲學特征以及發(fā)育規(guī)律,為聽障兒童單字調的研究奠定基礎。 其次,本研究通過主觀聽感知和聲學分析相結合的方法研究了30名3-6歲聽障兒童的聲調發(fā)音情況,總結聽障兒童聲調異常的主要錯誤類型為:一聲錯誤類型:輕微降調;二聲錯誤類型1:平調,二聲錯誤類型2:輕微降調;三聲錯誤類型1:平調,三聲錯誤類型2:輕微降調;四聲錯誤類型1:平調,四聲錯誤類型2:降調幅度不夠。此外還有一種總體錯誤類型:聲調單一。在此基礎上分析了各種錯誤類型的聲學特征和聲學參數(shù)值。 第三,本研究比較了正常兒童與聽障兒童特定錯誤類型的聲學參數(shù),獲得區(qū)別正常聲調和特定錯誤類型聲調的特征參數(shù),并總結錯誤成因是特定點的基頻值沒有下降。 第四,在對聽障兒童單字調發(fā)音特點研究的基礎上,本研究提出了聲調異常的治療框架,包括基礎性訓練和針對性訓練。在治療框架的指導下,進一步提出了系統(tǒng)的治療策略,以期對臨床治療提供指導和借鑒。
[Abstract]:Dystone is one of the common speech disorders in children with hearing impairment. Chinese is the tonality language, tone and vowel, consonant have the function of differentiating meanings as well. Therefore, the correction of dystone in children with hearing impairment is very important. However, most of the existing studies focus on the tone perception of children with hearing impairment, and there are few studies on tone pronunciation of children with hearing impairment, and there is a lack of systematic treatment strategies in clinical practice. Therefore, the purpose of this study is to explore the tone of monosyllabic words in children with hearing impairment by means of acoustic analysis, that is, the main error types and acoustic characteristics of monosyllabic pronunciation, and to establish the reference range of acoustic parameters. Furthermore, the systematic framework and strategy of tone abnormality therapy are put forward. Firstly, we studied the fundamental frequency curve and the reference range of acoustic parameters in 60 normal children aged 3-6 years by acoustic analysis to understand the acoustic characteristics and developmental rules of tone pronunciation in normal children. To lay a foundation for the study of single tone in children with hearing impairment. Secondly, by combining subjective auditory perception with acoustic analysis, this study studied the tone pronunciation of 30 children with hearing impairment aged 3-6 years, and concluded that the main types of tone abnormalities in children with hearing impairment were as follows: one tone error type: mild tone lowering; Two tone error type 1: flat tone, 2 tone error type 2: slightly down tone; 3 tone error type 1: flat tone, 3 tone error type 2: slight drop tone; 4 tone error type 1: flat tone, 4 tone error type 2: low tone amplitude is not enough. There is also a general error type: single tone. On this basis, the acoustic characteristics and acoustic parameters of various error types are analyzed. Thirdly, we compare the acoustic parameters between normal children and children with hearing impairment, and obtain the characteristic parameters to distinguish the normal tone from the specific error type, and conclude that the cause of the error is that the fundamental frequency of the specific point has not decreased. Fourthly, on the basis of the study on the characteristics of tone pronunciation in children with hearing impairment, a therapeutic framework of tone abnormality is proposed, including basic training and targeted training. Under the guidance of the treatment framework, a systematic treatment strategy is put forward to provide guidance and reference for clinical treatment.
