Fluent speakers stammer or even stutter on words especially when giving long explanations and even when speaking, the only difference is that you capitalize on it.

Nobody is a flawless speaker, that takes extreme dedication. Watch a Joe Rogan podcast. Some of the smartest people I’ve seen talk frequently stutter and stammer, and I’m just using a podcast as an example So try not to think about it, all it does is create fear, and fear is the precursor to stuttering. That’s basically true for everyone on this sub, whether they want to admit it or not
