Abstract

This study aimed at comparing the tongue contours of children with phonological disorders (PD) and of children with childhood apraxia of speech (CAS). The hypothesis was that children with PD have different tongue contours from those with CAS in Brazilian Portuguese. Five children with PD and five with CAS participated in this study. Data were collected and analyzed with the Articulate Assistant Advanced software. The target segment was analyzed using the frame corresponding to the point of maximum constriction of the tongue. Statistical analysis consisted of an SSANOVA. The data were pooled and the tongue contours of the children with PD and CAS were used to fit an SSANOVA for each target segment. The hypothesis was partially corroborated. Results showed differences in tongue contours between children with PD and with CAS for correct productions of plosives. Children with PD showed different articulation strategies in most correct and incorrect productions when compared to children with CAS.
