If people have speech recognition software and a word processor, just speak into the word processor, and then copy and paste the text it generates onto the page editors on this website. There's no need to create a speech user interface built into this website. Creating software that recognises people's speech is an extremely complicated thing, not to mention programming a text-story writing site to recognise such speech. It might be nice, but I think it would probably be a very complex addition to this website.
