Yes you right. In addition, anticipation plays a huge role in it. When you overthink what you will say, then you sttuter. The key, and what I try to do, is to trust your brain and don't think about what you will say before you talk, yes you can rehearse it on single time and then stop thinking and go to action. I 100% sure that we PWS doesn't have any issue with language, I can say that we have the ability to construct pretty good phrases in term of meaning. So we should trust our brain. On what I based to say that, is that talking is a subconscious process, like walking and bicycling, you don't think if you should move the right leg or the left one, it's the same for talking.
