@matthiasott @notabene I'm sure @tink will correct me if I'm wrong, but I imagine that a person who uses a screen reader to navigate the web is going to have it set up in a very particular way, with a preferred voice and probably speaking very many more words per min compared to say, an audio book.
But it might be nice to flip into an article's specified voice/CSS speech mode for the content, if one has been created, to get some more variety into their web experience. I'm intrigued by the idea!
