摘　　要：目的　探讨替牙期骨性反牙合对语音功能是否有影响及其影响程度。方法　选择 38例替牙期骨性反牙合患儿为研究组 ,随机选择 4 0例替牙期正常反牙合儿童做对照组。由语音专家对两组儿童的语音进行判听 ,记录错误音素及错误类型 ,并应用计算机语音工作站对错误音素进行语音声学分析。结果　 16 3.16 %的替牙期骨性错反牙合患儿存在发音异常 ,主要集中于 / z,c,s/等咝音上。 2研究组的错误音素的嗓音起始时间 (VOT)等于 0 ,没有明显清晰的频率下限 ,频率分布范围变宽 ,频率下限下降 ,能量增强 ,频谱伸入后续元音里。结论　大部分替牙期骨性反牙合患儿存在语音功能障碍。Objective To investigate the effects of skeletal malocclusion in mixed dentition on articulation. Methods 38 children with skeletal malocclusion in mixed dentition were selected as a sample group,other 40 children at similar mean age with normal occlusion were selected as a control group.Their articulations were evaluated by phoneticians and the discorded speech sounds were analysed by compurized speech lab. Results 63.16% of patients with skeletal malocclusion in mixed dentition had misarticulations,the sound errors foucused on sibilants (c,s,z etc.). The voice onset time(VOT) of resonant nate and resonant fricative nate of sample group were nought while that of the normal group were positive. Conclusion There is articulatory misfunction in most skeletal malocclusion patients in mixed dentition.
