Thanks for your question! Indeed, I know of people doing research on this topic right now. (I just got an email from someone the other day interested in this.) I don't know where the research will lead - it's all relatively new. But, I do believe that we will learn a variety of new ways to help people who stutter in the coming years as we learn more about brain structure and function. One thing that's important to keep in mind -- much of the research that's been done on these types of approaches to stuttering have focused on enhancing fluency, but that is not the only valuable goal of stuttering therapy. We can also do a lot to help people learn to cope with stuttering more effectively, and that can be done even without advanced technology.
