DAF and online exams?

DAF and online exams? So I've been using delayed auditory feedbacks for my therapy sessions (as in psychologist), and it has truly been helpful in making me able to speak more fluently. I don't use it often and try not to rely too much on it. Due to covid a lot of my uni exams are now online, and oral, so I was wondering if I could try the same thing (My stutter is severe). Obviously I would email my professor for a heads up. Do you guys have any experience of delayed auditory feedback devices used in university exams? I've been studying a lot for this exam, and I want to be able to communicate what I've learned. I have trouble using the techniques my speech therapist teaches me in high-anxiety situations.
