Is there a phobia for people who stutter?

Is there a phobia for people who stutter? I was out today and wound up talking to this cashier lady at check out, everytime I stuttered I noticed she'd like physically recoil and look panicked even after I said something to the effect of "it's just a stutter, I've had it my whole life." I know there's phobias of other disabilities like Achondroplasiaphobia which is the fear of people with dwarfism. Does anyone know if there's one for people with speech impediments? It's just been on my mind for the past like 5 hours and everytime I try to search it a different way on Google it just pops up with Glossophobia which is just the fear of speaking like performing public speeches and all that. It's not really an important question I know. It's just my curiosity gets the best of me and makes me search things up until I get an answer, it's part of my OCPD. It's minor OCPD but it still makes me need answers on minor stuff like this.
