Yes - The McGuire Programme. We work on relearning how to speak clearly and eloquently, with the help of physical speech tools. But thats just 20%. The rest is on overcoming the fear, anxiety, stress, etc that is both the cause and result of stuttering (never ending cycle hey?). There are tens of thousands of members on the programme and its highly effective, but like with any skill - sports, marital arts, education - takes a lot of practice. google it if you are interested - its global.
