One thing I wanted to point out... the diagnosis doesn't change from Autism/PDD-NOS to Asperger's just because the child begins speaking. I would be willing to be your child probably still has a large pragmatic speech delay, like nearly all children with Autism/PDD-NOS who do fine with functional speech. A pragmatic speech delay is still a serious issue, and causes my son no end of trouble with school and friends. (I've been on the hunt for an SLP for him for ages now!)
