Consider asking for any of the following accommodations: 1. use of text to speech technology, but during class, not before or after. 2. or just speaking, and making sure people wait during your blocks. Maybe agree on a signal to express "that was a block. I wasn't finished." when you get interrupted. It could be a "wait" hand gesture. Or choose one of your secondary behaviors as the signal. Both of these accommodations requires zero effort on the teacher and it increases your participation.
