Practice. Adapt. Overcome. I'm 29, and within the last 2 years 'mastered' the art of saying my own name (lol this late in the game :D) Seriously though, it's a matter of environment adaptation. You're not using that portion of your brain and vocal muscles because you, a stutterer like myself, likely recoil from many social situations. I worked in a research lab for the majority of my professional career so I had few opportunities to introduce myself. I moved up in my science career and meet with clients now. Through forced repetition and the undying tenacity of a stutterer, I managed to annunciate my name about 95% of the time. That 5% is just the human side of me where most people are. It took time, several cringe worthy moments, embarrassment and will power to get better at it but I did. Surely when I first started people thought 'He has a stutter'. Now it, even myself I think, 'He had a stutter, but he doesn't anymore.' Naturally you will shy away from situations that are negative. You attempt to 'bite the bullet' and force yourself into an uncomfortable scenario where you have the courage of a lion. You go to speak and all the sudden the train comes off the rails. Instead of growing from the experience, us stutterers run away, and fall into vicious negative feedback loop. Most stutterers I would argue rarely ever come out of this cycle and continue downwardly for a large portion of their life. Luckily evolution has a way of making weaknesses stronger if you're forced to use them. I don't expect the most pathological stutter to be cured, but it's the atrophy of these functions that we need to dust off to make them work and regress. This doesn't mean joining a Toasters club, and put yourself in high anxiety situations. It means ever forward, with constant adaptation. You either learn by practice or baptism by fire. I learned the latter, and I'm still here.
