Comparison of cross-language generalisation following speech therapy.

Little is known about the phonological development of children who acquire two languages sequentially in the preschool years. Some of these children will be referred for assessment of speech disorder. Distinguishing between delayed development due to the language learning environment and disorder is problematic in the absence of normative data on the typical phonological development of bilingual children. Another major issue concerns whether both languages require intervention, or only one because of generalisation to the other language. Treatment efficacy studies of 2 bilingual children are reported. The data indicate that different patterns of cross-language generalisation occur depending upon the deficit in the speech processing chain underlying the speech disorder.
