I work in schools in Madrid Spain. We are debating the usefulness of Cued Speech for reading in deaf children with CIs. What are the latest results on this and how generalizable to Spanish children are these results?
There are reasons to believe that Cued Speech may help deaf children with cochlear implants to learn to read and write. Cochlear implants provide auditory information that may be not precise enough to develop accurate phonological representations. Consequently, the reading and spelling skills of children with implants may be delayed compared to the acquisition of these skills by hearing children (with the same instruction). Those children who receive Cued Speech combined with the audio-visual input may develop more precise phonological representations, and better phonemic awareness which is an important skill for learning to read.
There are at least two empirical studies showing better reading, spelling, and reading related skills in deaf children with cochlear implants exposed to Cued Speech compared to deaf children with implants and not exposed to Cued Speech:
