I didn't say it was impossible for him to speak, but it is impossible for him to hear certain sounds with his aids.
I guess what I am taking for granted is that you want him to LISTEN and speak. People with a profound loss do not listen to running speech and understand it, it just doesn't happen. If they are oral, it is from intensive, long term speech therapy and lipreading (annd luck). But the majority of people born with a profound loss will not be fluent listening spoken language users.
