It seems like you adopted the neuroscience to stop stuttering which is built around rewiring and training your brain. Your right reading and talking slowly helps immensely. I always felt like I too was running out of breath while speaking but over articulation of words and speaking in short bursts and adding long stops helped me immensely reduce the speed of my speech. Stuttering lies in neuroscience and soon enough a neuroscience method will come sweep the world of stuttering but it really lies on the individual to work and have a strong mental focus when talking like you have done. Good job dude.
