Strange fluency on words after someone else says it, does anyone else experience this?

Strange fluency on words after someone else says it, does anyone else experience this? This might be difficult to explain but it is almost 100% with me or atleast 95% to be safe. Example situation: I'm anticipating a word coming up that I will have a stutter on or I'm not answering a question because of this anticipation but I know the answer. If someone else says the word or answer I can instantly say that word fluently. The same word I know I was going to stutter on for some reason when repeating or validating someone's response saying that same word comes out fluent. Does anyone else experience this weird phenomenon?
