I could never feel comfortable stuttering on purpose. What i did is to study fluent speakers. I discovered that fluent speakers use a steady and comfortable stream of air when they speak. The same way that allows stutterers to be fluent when they sing. I practiced breathing for speech which helped me to gradually become more fluent. I am presently basically stutter free I can finally say my name without stuttering. It has been a life changing experience to not stutter in front of people.
