摘要
为了探讨骨性Ⅲ类错畸形对语音功能是否有影响,我们以20名骨性Ⅲ类错畸形的成年患者为研究对象,由语音专家对其语音进行判听,同时应用计算机语音工作站(computerizedspeechlab)进行了语音声学分析。结果表明:①多数此类错患者存在语音功能异常,在zh、ch、sh、z诸辅音上最常出现发音错误,错误类型为发音失真(distortion)和发音替代(substitution)。②语音声学分析显示,与正常辅音相比,有发音错误的辅音频率下限下移,频率分布范围变宽,低频成份增加。本项研究结果表明,骨性Ⅲ类错畸形能导致语音功能异常,在口腔正畸外科正畸联合矫治骨性畸形的同时,应考虑患者语音功能的改善。
The purpose of this study was to investigate the effects of skeletal class Ⅲ malocclusion on speech articulation. The subject was twenty skeletal class Ⅲ malocclusion adults. Their articulations were evaluated by phoneticians and the disorded speech sounds were analysed by computerized speech lab. It was manifested that most of the adults had misarticulations, the most common speech sound errors were consonants (zh, ch, sh, z) and the types of errors were distortion and substitution. Compared with the nomal consonants acoustic analysis of the disordered ones showed that, the lower boundary frequency got down, spectrum distribution in frequency became widen, as well as the lower frequency components were enhanced. The results suggested that skeletal class Ⅲ malocclusion may cause deficiency in speech production. The improvement of speech articulation should be considered when the severe skeletal discrepancy was corrected by surgicalorthodontic treatment.
