【摘要】：目的探讨学龄前听障儿童不同语句语调的声学特点,为其语调训练提供参考。方法选取4~5岁听障儿童和健听儿童各20例,以自编陈述和疑问语句为测试材料,获得两组儿童边界调的起点值、终点值和频率值,分析不同语调类型和儿童类型之间的差异及相互影响。结果两类学龄前儿童疑问句边界调的起点值、终点值和斜率值均大于陈述语句;与健听儿童相比,听障儿童陈述语调的第一声边界调斜率值偏低即音高下倾趋势过多,第四声边界调起点值、终点值均偏低即音高曲线整体下降过多;听障儿童疑问语调的第一、二、三声边界调斜率值偏小,即音高上扬趋势不足,第一、四声边界调起点值、终点值都偏低,即音高曲线整体提高不够。结论学龄前听障儿童陈述语调比疑问语调掌握好,在疑问语调训练时,可以依据其边界调音高曲线的起点、终点和走势特征进行针对性训练。
[Abstract]:Objective to explore the acoustic characteristics of different sentence intonation in preschool children with hearing impairment and to provide reference for their intonation training. Methods A total of 20 children with hearing impairment aged 4 and 5 years old and 20 children with hearing impairment were selected. Using self-made statements and interrogative statements as test materials, the starting point, end point and frequency of the boundary adjustment of the two groups of children were obtained. The difference and interaction between different intonation types and children's types were analyzed. Results the threshold value, end point value and slope value of the two types of preschool children's interjections were higher than those of the statements, and compared with the children with hearing impairment, the first tone of the children with hearing impairment was lower than that of the children with hearing impairment, that is, the first tone of the children with hearing impairment was lower than that of the children with hearing impairment. The threshold value of the fourth tone boundary adjustment is too low, that is, the overall pitch curve of the children with hearing impairment is too low; the first, second, and third tone boundary adjustment slope values of the children with hearing impairment are small, that is, the pitch rising trend is insufficient, the first and fourth sound boundary tuning threshold values, The end point is low, that is, the pitch curve is not enough. Conclusion Preschool children with hearing impairment have a better command of declarative intonation than interrogative intonation. In the training of interrogative intonation, they can be trained according to the starting point, ending point and trend characteristics of the boundary tuning high curve.
