Ah reading! I remember I used to stutter when having to read in school. As I read, I'd definitely hit speech blocks but when I memorized something and had it down in my head, I never stuttered! I don't understand why but that was the difference that allowed me to present at a job I was in. I just had the lines rehearsed and said it from memory, like it didn't even feel like I was talking to anyone, just rehearsing, if that makes sense.
