Abstract:
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 intelligi-bility 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 ordina-ry 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 artic-ulation intelligibility(P＜0.05).In the sentence corpus,all the other indexes except mandibular distance were sig-nificantly 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.
