Advice for a non-stutterer

Advice for a non-stutterer Hey folks, I’m joining a DND group and yesterday I spoke with the DM over voice chat for the first time (we met through a discord server) and while I don’t have much of a frame of reference it became apparent that he has what seems to be a pretty severe stutter. He’s a young kid (early high school) and is excited to be running his first game. I guess I wanted to ask y’all if there’s anything I can do to make things less stressful for him and also if there’s anything I should avoid doing. Like I said I don’t really have any experience and I don’t want to say or do anything hurtful through my ignorance. Any insight is appreciated.
