You can either change the word or drop the first letter of the word. Like if I had to say “apple” but knew I was gonna stutter at “a-a-apple” I would say “pull” fast. If you do it fast enough In regular conversation people can’t tell. Or if my name was “Jenny” I’d say “enny”. Other people’s brains fill in the blank subconsciously most the time from what I’ve found. Doesn’t work all the time though.
