An analysis of the speech of five Down's syndrome adolescents.

his paper presents an analysis of the speech of five Dutch-speaking adolescent girls with Down's syndrome. The analysis includes a phonetic analysis, a substitution analysis, and a phonological process analysis. The results indicate that the speech errors of Down's syndrome adolescents are for the greater part identical to the error patterns observed in young normal children, supporting the view that the misarticulations in mongoloid subjects are mainly the result of a delay in speech development.
