For me, I’m a native English speaker who stutters and I’ve gotten the chance to speak in Italian, French, and Greek with members if the stuttering community. I find that I stutter the same amount in any language, but I stutter on different sounds in each language (ex. I get stuck on the French “r” a lot). I think it’s really interesting that the language I’m speaking doesn’t really affect my stuttering that much, but that’s just my personal experience.
