Certified speech therapist here. In my experience, dealing with stuttering is all about regaining control. If volutional stuttering puts you in control, then it is an improvement. I think the idea is if you feel like you're going to stutter, make yourself stutter. At least then you're in control of the stuttering. This actually does have some neurological basis, as it takes your speech from involuntary to voluntary, which is a different neurological pathway. However, there are lots of techniques like this, where you're changing your speech enough that it is voluntary. All of them work until they become habit. Then it is involuntary again, and the stutter comes back. However, I like the aspect of learning to accept stuttering as a part of who you are. It is not something to be feared or celebrated; it is just a thing that is. Another technique that embraces this principle is self-disclosing. It is simpler than it sounds. When you meet someone who you need to talk to, you say something like, "I stutter, which makes it take longer for me to get my words out, so be patient, please." No apologizing, no over-explaining, just a basic statement of fact. It works so well, bc it alleviates the anxiety about whether someone is going to see you stutter, and it brings the liatener into the communication process in an open and honest fashion. There are lots of internet articles about self-disclosure. Stammurai has a good one. Good luck!
