腭裂术后患者的听力对不同频率辅音辨别的影响

摘要

Objective:To investigate the effect of hearing on consonant discrimination in postoperative cleft palate patients.Meth-ods:30 subjects after surgery of cleft palate were examined for hearing and evaluated for speech,error frequencies of consonants were counted.According to the Chinese tone frequency and intensity distribution and measurement table of dysarthria in Mandarin,hearing and speech were divided into 3 ranks respectively.Spearman rank correlation analysis was used to determine the relation of consonant discrimination with hearing.Results:Higher error frequency of consonants (form high to low)were [t],[ts],[k],[],[s],[t] and [k'].There was close correlation(P <0.05)between hearing and discrimination of consonants including [t],[t'],[k],[k'], [t],[t'],[],[ts],[ts'],[s],[t],[t'],[]and [],while the discrimination of consonants [b],[m],[f]and [n]showed no significant correlation with hearing(P >0.05).Conclusion:The hearing of postoperative cleft palate patients affect the consonant discrimination that mainly in the high frequency region,while low and middle frequency consonant discrimination have no influence. Other feedback channels need to be considered in speech training for high frequency consonants.%目的：探讨腭裂术后患者的听力对不同频率辅音辨别的影响。方法：对30例腭裂术后患者行听力检查和语音效果评价，统计辅音错误频次，依据汉语语音频率强度分布表和普通话构音测量表，将听力和语音资料各分成3个等级，Spearman等级相关分析，寻找与听力相关的辅音。结果：错误频次较高的辅音排序（从高到低）为：zh，z，g，sh，s，j，k；腭裂术后患者的听力对语音的辨别有显著影响（P ＜0．05）的辅音为：d，t，g，k，j，q，x，z，c，s，zh，ch，sh，r；无影响（P ＞0．05）的辅音为：b，m，f，n。结论：腭裂术后患者的听力主要影响高频辅音的辨别，对低频和中频辅音的辨别影响不大，语音训练腭裂患者时，针对高频辅音，可以尝试多种反馈途径。
