>*"I believe that if a stutterer was to take a vow of silence, i.e. to stop speaking, and only break that silence in the event that they know that what they aim to say will be said without stuttering."* How can we predict in advance if we will experience stuttering or fluency? From my perspective, humans are unable to foresee whether their speech motor movements will initiate (or inhibit) while talking. I cannot even foresee whether I will initiate leg movements within a few seconds while walking, and this is despite the fact that leg movements are entirely subconscious motor behaviors over which I have control when initiating them. While I hold a contrary view on humans' ability to predict the future, I genuinely believe that making a vow (as you pointed out) can be a valuable intervention, particularly in strengthening the process of our decision-making, often referred to intention-forming \[*to instruct execution of motor movements, such as moving the lips and other speech muscles during a speech block*\]
