Thanks for sharing, this is another good data point in favor of this. I will say though, my stutter was so bad that I had problems reading paragraphs during school. I used to dread it when we'd go around in class, and I would mentally try to rehearse my paragraph in my head before my turn came. So I still found benefit in this even though I was once at a point where I could only read aloud in isolation. There is something about other people hearing my voice, that causes my speech to switch up.
