I have a group of remote friends who often play RPGs by written message only - primarily playing live. I'm starting up a new game, and one of the players who's asked to join has moderate dyslexia, and has had problems in the past both typing longer messages and keeping up with reading a constant flow of messages.
I want them to be able to play in this game. However, in our case, voice chat is not an option for continuing play - it's not even a remote possibility; simply asking people if they can play by voice won't work. And, my dyslexic friend doesn't want to use a TTS system.
To my un-accessibility-trained eye, this has sort of exhausted the list of possibilities. Is there any way I can help them participate that I'm not seeing, or is this situation just not one in which this person can effectively participate?
