One way is “flooding” or desensitization. Intentionally stutter. A lot. Start at home alone. and stutter stutter stutter. It can actually be fun or amusing to do with trusted people. Then stutter on purpose with trusted friends and family. Then out in public. This s the hard part. It’s not easy to intentionally stutter in public—but the more you put yourself out there and talk even with stuttering the less fearful you will be. The point is stuttering loses its power when you are not avoiding it but letting it happen. You aren’t having tension and judgements about it. It just is. If you do those things you’ll find you stutter “more easily”. Fluent stuttering if you will. If you can allow or welcome stuttering then you will stutter less, struggle less, and move on quickly to the next word. Depending on how severe your stuttering is you can utilize techniques to quickly move beyond the stutter. They are called “stuttering modification” techniques because you are not trying to avoid the stutter but gently move through it. I recommend Stephan SLP online if you are interested in independent practice. He’s great because he has so many helpful video demos and because he stutters himself, so he understands. He is not “cured” but has learned how to stutter more fluently.
