I studied the speech of fluent speakers to find out why they don’t stutter. I found it has to do with easy and continuous airflow through the vocal cords. I found that you tend to stutter when you activate the Valsalva response. Once I was able to voluntarily control my Valsalva response I was able to produce easy and continuous airflow. I was then able to produce fluent speech. I have not had a relapse since then. It has been a life changing experience.
