Wow that is really fascinating. Does this really work in increasing fluency? My only concern is that the metronome is a distraction. Like the chorus effect (where stutterers can speak as long as they are talking over someone else at the same time). I think I want to give this protocol a try. Do you know if the fluency gains achieved by this "programming" are maintained over the long term? So, would I do this with some vietnamese text and/or an english book and just work my speed up as both a method for vietnamese and also general fluency?
