Even when I convey my thoughts pretty smoothly with minor stutters here and there, people still point out my stutter and ask if I'm doing anything to cure it. I would advise you to just focus on the interview. Even if you stutter, take the interviewer along the process of conveying your answer. I've never really thought about it this way and I have always thought about the answer which I want to give and to convey the answer through my stutter no matter what but think of it as a game where the interviewer is rooting for you to tell the answer. For the typical interview questions, they know the answer, so just take them along on your bumpy ride journey. For example, if they ask what machine learning frameworks do you know and you're stuck on "Tensorfl" and then complete it by saying "Tensorflow." By the time you give the answer for "Pyto", they are rooting for you to say "Pytorch." I have had bad experiences with interviews but it is always nice to have a mindset that the interviewer is a good person and is accommodative till it is pretty clear that they are not! :P
