Thanks for your comment! I'm already breathing from my diaphragm. Tbh I've already accepted my stuttering, I just want to minimize it for my work. So that's why I want to find a natural way to reduce it instead of using techniques. I think unnatural techniques are very risky. That's why I want to see if there are natural ways of making sounds my body uses that I can adopt into my casual way of speaking. I will definitely look into Del Ferro!
