听障儿童双字调三声发音的难度分析

An Analysis of the Dififculty of the Third Tone in the Di-syllabic Tone for Hearing-impaired Children

目的：分析听障儿童双字调中三声的发音情况，探讨其发音的难度层次，为听障儿童三声的发音训练提供参考依据。方法以8种双字调中三声的组合为基础，测试120名3～5岁听障儿童的三声发音情况。结果听障儿童双字调中三声不同组合形式的发音难度差异有显著统计学意义（P＜0.01），从易到难依次为3-1和3-4组合；3-2、3-3（前）和3-3（后）组合；2-3、1-3和4-3组合。结论听障儿童双字调三声的发音难度可划分为3个层次，在训练时应遵循难度层次依次进行，以提高康复效率。

Objective To investigate the difficulty of the third tone in di-syllabic tone for hearing-impaired children and to provide references for the rehabilitation training. Methods Based on 8 different patterns of the third tone combination,120 hearing-impaired children of 3 to 5 years old were tested to investigate the pronunciation of the third tone in the di-syllabic tone. Results The difficulty levels of the different patterns of the third tone combination in the di-syllabic tone were significantly different（P＆lt;0.01）. The difficulty levels from easy to difficult were 3-1 and 3-4 tone, 3-2, 3-3（front） and 3-3（back）tone, 2-3, 1-3 and 4-3 tone. Conclusion The third tone in di-syllabic tone can be divided into three levels of difficulty for hearing-impaired children. The speech training course for the hearing-impaired children should be designed according to the difficulty levels in order to improve the training efficiency.
