No I don't have that issue. If anything, the reading aloud helps my understanding of complex material. Though sometimes I may need to pause and think about what I read before the connections become clear, or even re-read the material 2 or 3 times before I understand what is going on. If that fails, then I try to discuss it with or try to explain to another person, that is often surprising handy at helping me understand confusing things. The explaining of things to another person who is aware of your speech issues but willing to be patient, has been really powerful for me in becoming better at speaking in informal situations. Feel free to DM me if you want to chat some more.
