Yep. Reading aloud is just about impossible for me, even after all these years of learning different coping strategies and fluency tricks. I simply refuse to do it. I used to be in a writing group and I told the instructor that I can't read aloud (which was a big part of the class) and they said 'fine' and I even installed a 'text to speech' app on my phone so which could read aloud what I'd written in that class that day, so I was still participating like the other students but just using an app to read aloud my writing. If you tell your teacher you have a speech issue and don't want to read aloud I'm sure they'd agree to let you skip reading aloud in class.
