Yes, that’s how it works for me. I know well in advance what word I’m going to stutter on. You’re mind is like a computer and processes information so quickly that it’s scanning 15+ words ahead in the conversation and identifying “problem” sounds or words. The good news is your subconscious is a fool and believes anything you tell it. You can also tell it you’re going to say the word fluently. It takes a ton of work to re-wire the subconscious but it can be done and then you can absolutely refuse to stutter when those thoughts appear.
