![]() 2009 The Speech Pathology Association of Australia Limited. The childs phonological process use is documented to be non-developmental or outside of the expected developmental range, as evidenced through at least one. In typical development the substitution of non-apical consonants by apical ones duo to greater flexibility and control of the tongues apex, is also observed (. Whether or not speech disorders are related specifically to ASD, their presence adds an additional communication and social barrier and should be diagnosed and treated as early as possible in individual children. Non-developmental distortions occurred relatively frequently in the children with ASD and previous studies of adolescents and adults with ASDs shows similar errors, suggesting that they do not resolve over time. non-developmental) phonological processes, e.g. Developmental and non-developmental phonological processes persist in the speech of children with mild to profound hearing loss compared to their peers with. The speech of children with ASD was characterized by mainly developmental phonological processes (gliding, cluster reduction and final consonant deletion most frequently), but non-developmental error types (such as phoneme specific nasal emission and initial consonant deletion) were found both in children identified as performing below the normal range in the standardized speech test and in those who performed within the normal range. Unintelligible speech in childhood is often characterised by the use of unusual or deviant (i.e. These error patterns start to fade out as children get older and their speech sound repertoire increases. Nondevelopmental phonological processes are indicative of disordered versus delayed phonological development, and are rarely seen in normal development. Overall 41% of the group produced at least some speech errors. Developmental phonological errors are error patterns in children’s speech that are normal and occur as part of the speech development process. Although all the other children had standard scores within the normal range, a sizeable proportion (33% of those with normal standard scores) presented with a small number of errors. On a standardized test of articulation, the minority (12%) of participants presented with standard scores below the normal range, indicating a speech delay/disorder. Estimates of the incidence of developmental phonological disorders in the 5. Participants were 69 children aged 5-13 years 30 had high functioning autism and 39 had Asperger syndrome. non-developmental) phonological processes, e.g. This study involved a qualitative analysis of speech errors in children with autism spectrum disorders (ASDs).
