I’m speech impaired and a large amount of streaming relies on the streamer communicating with their audience, although typing while gaming is difficult I do think the ability to turn text into speech built in twitch for streamers would allow many streamers like me to produce content other than just gaming, I for one would love to do talk shows with friends about gaming/movies/anime etc but I’m held back because there’s no support for speech impaired streamers on twitch as far as I’m aware.
