摘　　要：利用三维电磁发音仪采集聋哑学生和正常学生普通话元音/a/,/i/,/u/,/o/,/e/,/ü/的声学和运动学数据,对其发音共振峰、发音时长、唇部和舌部的最大位移、最大速度的特征参数差异及不同特征参数间的关系进行分析研究。结果表明:与正常学生相比,在声学方面,聋哑学生在元音/i/和/e/的第一共振峰(F1)、所有元音的第二共振峰(F2)、所有元音的发音时长在上存在显著性差异具有统计学意义(P<0.05);在运动学方面,聋哑学生唇部的最大位移和最大速度均高于正常学生,舌部的最大位移和速度低于正常学生。研究结论可为病理语音研究提供理论基础和指导依据,为患者的医疗诊断和康复训练提供可靠技术支持和帮助。Acoustic and kinematic data for vowels of /a/,/i/,/u/,/o/,/e/,/ü/ were collected using 3D EMA.Our study explored the possible relationship between formant,duration,maximum displacement and velocity of lip and tongue.For acoustic parameters,the results show that the mean value of F1 on vowels /i/ and /e/,the mean value of F2 on all vowels,and duration on all vowels were significantly different between participants with hearing impairment and normal person (P<0.05).For kinematic parameters,the results suggest that the participants with hearing impairment showed a higher displacement and velocity of lip than the normal group,while,a lower displacement and velocity of tongue than the normal group.The conclusion of this study about participants with hearing impairment can provide support and help for pathological phonetic study and speech rehabilitation training.
