If you have what I have which is a stuttering brain then things become complicated. The stuttering brain does not understand what it means to be fluent. You may try to use whatever techniques you normally use to be fluent your brain will do whatever it can to stutter. This is the brain’s comfort level. When you fight with your brain chances are you will lose. I found the only way to win with the brain is to teach it specifically what you want it to do. I taught my brain not to activate the Valsalva response when I talk allowing me to have a steady and easy airflow through my vocal cords. This allowed me to become fluent. As I repeated the process many times everyday the brain began to understand what I wanted it to do. My brain learned how to allow my vocal cords to have an easy and continuous airflow. The greater the consistency of the airflow the less I stuttered. I was able to reach the level where I was basically stutter free. I hope this helps.
