Don't call them interruptions. Call them overlap or simultaneous talk.

Hitches in the turn-taking may be marked by louder speech, higher pitch, or faster speech. SOmetimes speakers let their speech be long and dran-out to wait for the end of someone's simulaneous talk.

Post-resolution hitches are common and include nervousness (repetition), pauses and drawn-out speech.
