Most will say no, that it could just be practiced. I would usually agree but a year ago my speech therapist recommended this device for me (28m) it doesn’t work for everyone but she thought it would be great for me. & it was! It almost stopped my stutter over a couple weeks with lots of practice & training. But you can’t just buy one online it has to be finely tuned to your voice via a speech therapist. https://speecheasy.com/devices/
