Have any of you practiced repeating a specific word over and over to yourself and eventually stuttered less on it?

Have any of you practiced repeating a specific word over and over to yourself and eventually stuttered less on it? I just had that random idea and have been trying to train myself to self improve these days. I have a few trouble words in my life that I need to say a lot, and was wondering if just repeating that thing over and over would help make it easier to say when the times come. I would say my stuttering is normally mild with the occasional super good days, and was a lot worse when I was younger. I'm gonna try this for the next couple of days and let you guys know.
