What other speech habits accompany your stutter?

What other speech habits accompany your stutter? Doing some reflection on my speech patterns and thought about a habit I have, I'm wondering if anybody else here has something similar. It doesn't necessarily follow every time I stutter, but I find myself repeating portions of a previous sentence quietly to myself. Since joining this sub and learning more about things like echolalia, I don't believe it's related to that. Without a stutter, it almost feels like an automatic affirmation that I spoke fluently and correctly. If I did stutter in the sentence, It's more about quietly whispering it to myself just to prove i can say it without stuttering. It doesn't come out very often but when i catch myself doing it, I don't really know why. I just do it. Does anybody else have a speech/habit thing that isn't exactly just stuttering?
