An interesting side note, he scored the high end of average for his IQ, which was administered as a non-verbal test. Which most people when hearing him, would never think is the case. So don't you all wonder what he's saying inside his head that comes out scrambled?? I can't wait to hear it some day. ;)
You'll be able to understand the word 'yes' very clearly, but pretty much only approximations of most other words, but the approximations are getting better, and that is the first step. So the word, 'No' sounds like, 'Oh', but in context, you know what he's saying.
