I've honestly never heard of this, this is brilliant ! Also, the speech therapist I went to was nice and friendly but kept talking about learning to live with the "glitch" and saying there is no possible way to fix it and only told me techniques I've used or tried before. It seemed useless and I was also given worksheets to do and told to give my teachers in school at the time a little leaflet to educate them on my stutter, which is unnecessarily embarrassing.
