Take this opinion for what you will.. ..but I believe stuttering to be an anxiety disorder. Hear me out: at some point a long the way we've learned that we *must* speak completely fluently. Which is a load of bollocks. **Everyone has disfluencies**, it's natural. So buried deep in our unconscious mind, we have this script saying we should be perfect. What's helped me to deal with it more than anything is daily meditation. I started with guided meditation, then went to 20 minutes of stillness. And eventually visited a Vipassana meditation center when I meditated all day, every day, for 10 days. And nothing helped me become more aware of these processes than that. I will always have disfluencies because I am normal. But now, when I stutter, I relax into it an allow my tongue and jaw to move where they need to so I can make the sound I'm trying to make. Don't aim to "beat" your stutter. It's a fool's battle. Aim instead to accept yourself and open to the present. If you begin to struggle, become aware and relax into it. I know it sounds esoteric but in the east they've been treating these kinds of problems (anxiety) with meditation for literally thousands of years.
