Deaf children's access to BSL is not a problem for 10% of children who have BSL-using parents - but what about the remaining 90%? If their parents learn and use BSL - a big 'if' - then this should produce children with age-appropriate use of BSL. However, in practice the family is required to be the primary deliverers of a language they have yet to learn. This is not an empowering situation for parents. Although the families' capacity to communicate in BSL may improve over time, the crucial time that a young child needs access to a complete, grammatical language is in its first few years and this is usually before the family is competent in BSL. Visiting CSWs and BSL-using ToDs have an important role to play but it is hard to compensate for impoverished language within the home. Consequently many BSL-using children will arrive at school with delayed language. Despite expert and dedicated teaching, problems of grammar and vocabulary may remain. Even if the deaf child acquires full, grammatically correct, vocabulary-rich BSL they still may not be able to communicate with their parents... and... they have yet to learn English. Hearing families are perfectly able to model English (or the home spoken language), but how accessible is it to a deaf child?
One solution to these problems is to modify the aims of bilingualism and concentrate on ensuring that children learn primarily written English. But is this full bilingualism? Additionally, BSL is not a direct or easy route to literacy in English. Do children brought up this way have average, or even functional, written English skills? The evidence, and the increasing use of 'modified' language would suggest that they do not.
The sound-based system of Cued Speech can be learnt in 20 hours, so twin problems of
a) complete and early access to the home language in a hearing family and
b) full and easy access to sound-based language leading to age-appropriate literacy
can be overcome by its use in the home.
But how can Cued Speech fit into a bilingual model?
