摘　　要：目的探讨痉挛型脑瘫儿童的构音声学指标特征及其与构音清晰度的相关性。方法选取6~12岁脑瘫儿童和普通儿童各17例为研究对象,采用单元音、单字和句子三种语料,评估两类儿童的构音声学和构音清晰度表现,并探究二者间的相关性。结果痉挛型脑瘫儿童在三种语料中的构音清晰度均低于普通儿童(P<0.01),表现为:单元音>单字>句子;在单元音语料中仅下颌距、舌距显著小于普通儿童(P<0.05),且仅下颌距和元音空间面积(vowel space area,VSA)与构音清晰度显著相关(P<0.05);单字语料中,下颌距、舌距和VSA显著小于普通儿童,元音椭圆面积(vowel ellipse area,VEA)显著大于普通儿童(P<0.05),除VSA和共振峰集中率(formant centralization ratio,FCR)外,其他指标均与构音清晰度显著相关(P<0.05);句子语料中,除下颌距外其他指标均显著差于普通儿童(P<0.05),且所有声学指标均与构音清晰度显著相关(P<0.05)。结论脑瘫儿童构音声学指标特征和构音清晰度均较差,语料复杂性会影响二者的相关程度。Objective To investigate the articulation acoustic characteristics of children with spastic cerebral palsy and their correlation with articulation intelligibility.Methods A total of 17 children with cerebral palsy and 17 ordinary children aged 6-12 years were included in the study,and the articulation acoustics and articulation intelligibility performance of the two types of children were compared by using three kinds of corpus:monophthong,single word and sentence,and the correlation between them was studied.Results The articulation intelligibility of the monophthong,single word and sentence corpus of children with spastic cerebral palsy was lower than that of ordinary children(P<0.01),as follows:monophthong>single word>sentence.In the monophthong corpus,only mandibular distance and tongue distance were significantly lower than that of ordinary children(P<0.05),and only mandibular distance and vowel space area(VSA)were significantly correlated with articulation intelligibility(P<0.05).In the single word corpus,mandibular distance,tongue distance and VSA were significantly lower than that of ordinary children,while vowel ellipse area(VEA)was significantly higher than that of ordinary children(P<0.05).All other indexes except VSA and formant centralization ratio(FCR)were significantly correlated with articulation intelligibility(P<0.05).In the sentence corpus,all the other indexes except mandibular distance were significantly worse than those of ordinary children(P<0.05),and all the acoustic indexes were significantly correlated with articulation intelligibility(P<0.05).Conclusion Children with cerebral palsy have poor articulation acoustic cha-racteristics and articulation intelligibility,and the corpus complexity will affect the degree of correlation between the two.
