Imagine a world where IEPs included speech therapy. I can find a lisp or a stutter endearing, but I know for a lot of people it's a huge source of embarrassment and social anxiety. If there's a term for the manner of speech he's using I don't know it, but I have heard it a lot from almost exclusively guys, and most if not all seemed to have some difficulties with socialization. I'd be curious to know if there's a casual connection either direction there, as I could see how having fewer face to face conversations, especially in early development, would make it harder to learn to produce the full range of sounds needed for speech in a natural and comfortable way. And how likewise having difficulty producing speech in a natural and comfortable manner would make one shy away from interactions requiring it.
