That's good the breath balance test? The truth is its about the mind. You have to be conscious on how hoy want to bring out the word from your mouth. That's what I learn. Your method too is very good. I'm going to use the method as from today. I can have a conversation, I can talk but I stutter mildly now because I went for speech easy session last 2 weeks. I went for hypnosis therapy and it helped too. My stutter has reduce drastically. When I was a little kid, I had a friend who stutter. I copied him when I was 5 and it got to me. There was one time when I said to myself that I'll stop stuttering and it work for a 1 week. It came back again. This happened when I was tennager.
