摘要
目的探讨3～6岁极重度听障儿童单元音共振峰的平均值与健听儿童的差异，为指导听障儿童的语言康复训练提供参考。方法使用语音工作站采样分析，让10名3～6岁的极重度听障儿童在自然舒适状态下发／a／、／o／、／e／，／i／、／u／、／u／6个元音，每个音持续3s以上，并截取各声样中的3s平稳段进行声学参数的检测和分析。同时，与同年龄段健听儿童的数据做对照。结果听障组6个单元音的3个共振峰与健听组相比较，所有元音的F1无显著性差异（P〉0．05）；元音／o／~n／u／的F2无显著性差异（P〉0．05），其余各元音的F2有显著性差异（P〈0．05）；所有元音的F3都有显著性差异（P〈0．05）。结论极重度听障儿童的单元音共振峰与健听儿童有差异，这可能是引起听障儿童发这些元音不清楚的原因之一。
Objective To study the potential differences in average pure vowel formants between profoundly hearing-impaired children and normal-hearing children and to provide guidance for speech rehabilitation training for hearing-impaired children. Methods The voice samples were obtained from ten profoundly hearing-impaired children of 3-6 years old as they pronounced /a/, /o/, /e/, /i/, /u/ and /0/ naturally with each sound lasting over 3 seconds. The 3 s stable stage was obtained from each sound sample for acoustic parameter analysis. These data were compared with those of normal-hearing children. Results The three formants of 6 vowels by the hearing-impaired children were compared with those of normal-hearing children and no significant difference was found in F1 of all the vowels（P〉0.05）. No significant difference in F2 of/o/and /u/（P〉O.O5）was noted, but significant differences in that of other vowels（P〈0.05） observed.The significant differences were also observed in F3 of all the vowels （P〈0.05） between hearing-impaired and normal-hearing group （P〈0.05）. Conclusion There are significant differences in pure vowel formants between hearing-impaired and normal-hearing children, which may be one of the reasons why profoundly hearing-impaired children can＇t pronounce the vowels clearly.
