摘　　要：目的探讨神经性言语障碍患者单、复韵母构音运动的声学特征。方法在上海市多家医院收集24例40~81岁的神经性言语障碍患者(患者组),在上海市社区收集24例40~80岁的健康成人(对照组),从两组跟读含有不同韵母的语音样本中,提取单韵母/a/、/i/、/u/的第一、二共振峰(F1、F2),并计算出下颌距、舌距、元音空间面积(vowel space area,VSA)、元音清晰度指数(vowel articulation index,VAI);提取复韵母/ai/、/ua/、/uai/的第二共振峰并计算其斜率,比较不同语料任务下两组受试者的声学指标。结果单韵母任务下,患者组/a/的F1、/i/的F2、下颌距、舌距、VSA、VAI极显著小于正常对照组(P<0.01),/u/的F2极显著大于正常对照组(P<0.01);复韵母任务下,患者组/ai/、/ua/、/uai/的F2斜率均显著小于正常对照组(P<0.05)。结论神经性言语障碍患者单韵母构音运动范围减小,运动位置呈现集中趋势;复韵母构音运动速度减慢。Objective To investigate the acoustic characteristics of monophthong vowels and compound vowels articulation movement in patients with dysarthria.Methods A total of 24 patients aged 40~81 years old with dysarthria from hospitals,and 24 healthy adults aged 40~80 years old from communities in Shanghai were recruited.The first and second formants(F1,F2)of monophthong vowels/a/,/i/,/u/were extracted from the speech samples,and mandibular distance,tongue distance,vowel space area(VSA)and vowel articulation index(VAI)were calculated.The slope of the second formant of compound vowels/ai/,/ua/,/uai/was extracted and calculated.The acoustic parameters of two groups of subjects were compared under different tasks.Results Under the monophthong vowels task,F1 of/a/,F2 of/i/,mandibular distance,tongue distance,VSA and VAI in the patients were significantly lower than those in the control group(P<0.01).F2 of/u/was significantly higher than that in the control group(P<0.01).F2 slope of/ai/,/ua/,/uai/was significantly lower than that of the control group(P<0.05).Conclusion The space of monophthong vowels articulation movement was reduced in the patients with dysarthria,presenting a state of aggregation.The speed of compound vowels articulation movement was decreased.
