Ok then, I have another tip that seems to work for most people (btw I'm not a speech therapist I'm only recommending what works for me) There is two hemispheres of the brain (the left and the right) the left hemisphere is where we normally speak and the right hemisphere when we sing (I call this the melody method) Try singing a song and see if you stutter or not If it does work, then instead of trying to talk normally (which you will stutter) but instead try to mix the two, if you find yourself stuttering resort to singing while you are speaking to finish your sentence, after you start practicing it should sound normal. Hope it helps.
