Abstract:
Objective To study whether there is a difference in the percentage consonants correct(PCC)of children with functional speech sound disorders(SSD)at different ages,and to explore the distribution in types of consonant errors at different ages.Methods A total of 172 children with ages from 4 to 7 years who were diagnosed with functional speech sound disorders and admitted to the Department of Rehabilitation of the Third Xiangya hospi-tal of Central South University participated in the study.The children were divided into three groups according to their ages:Groups 1 to 3.Groups 1,2,and 3 consisted of 97,45,and 30 children,respectively(Group 1:63 boys and 34 girls,aged 4 to＜5 years;Group 2:36 boys and 9 girls,aged 5 to＜6 years;and Group 3:36 boys and 9 girls,aged 6 to＜7 years).Picture-naming task was used to assess children's phonology.The types of consonant error were recorded and the percentage consonants correct(PCC)and the incidence of consonant errors in different places of articulation(stopping,affrication,frication,nasalization,and lateralization)was calculated.Results ①There was no significant difference in the PCC results among the three groups(P＞0.05).②There was a significant difference in omission errors(Z=6.531,P=0.038＜0.05),but not for substitution and distortion errors among the three groups(P＞0.05).③The omission of the lateral/l/was major among the three groups of children.④There were more stopping,affrication and frication in all three groups of children,yet no significant difference in the results of incidence of consonant errors in different places of articulation(stopping,nasalization,affrication,frica-tion and lateralization)among the three groups(P＞0.05).Conclusion There was no significant difference in the PCC among children with functional speech sound disorders at different ages.There were obvious differences in the distribution of omission errors in different age groups,suggesting idiosyncrasy.Children with SSD demonstrated similar characteristics of consonant phonetic errors at different age stages,included mainly the omission of the lateral/1/and more stopping,affrication and frication.
