A bit confused here with what you mean? Tyler was moderate/severe to severe at birth, hearing aids at 5 months old, signs for the past 2 years as well as constant speech & SLP. I know he's getting some speech (definetely not all but some) so doesn't that give him something?
Ok, let me try to explain....
There are sounds that he has never heard. In fact, there are speech sounds that he has never heard. I would guess that he can hear (and say) all vowels and low frequency sounds like "b" and "m". Now, since there are sounds he has never heard, his brain has changed. The longer he goes without being able to hear those sounds, the less likely his brain is to EVER be able to interpret those sounds. So, even if he got a cochlear implant, the reason he would be less successful than a child who was implanted at 6 months old would be his brain. But on the other hand, he would be MORE successful than a prelingually deaf adult, because his brain did learn to interpret more sound than theirs. Plus, he is still younger, so his brain would be able to "remap" some with the new imput.
So, it has nothing to do with therapy but everything to do with the brain! The whole point of AV therapy is NOT to teach words, but to teach the brain how to listen and understand sound. That is why it is so different from traditional, old school, speech therapy.
