I would be the council member that uses it. The speech recognition itself doesn't work with this site. I use windows speech recognition from Microsoft, but I use to use Dragon speech recognition for law enforcement in the past. I wouldn't advise purchasing it in any of it's forms as newer computers and programs have it for free.
I advise you don't attempt to try any of the forms on chat unless you ask a mod first or do so in a coven chat. Mine doesn't work with chat and comes up as all symbols, but I can speak into my word format and copy and past information into chat without an issue. I often the same with posting on forums, but it often comes out with a few symbols I don't want in the conversion, however it's not a major issue.
You aren't likely to find all the books you want on audio, but Microsoft does have an audio program. You should be able to copy and past posts off this site into the word program and use the audio on the computer can play it as the conversion issue only occurs from Microsoft to the site, not the site to Microsoft.
