I am wondering if anyone can advise me on the best text to speech for the ipad 2. I need something that will do this for documents in pages (I think that is the only way to do documents?) I am deciding whether to buy my son's used ipad 2 or whether there is a reason I should spring for the new ipad. Though I am not sure if on the new one, Siri works for documents? I am told maybe Dragon for speech to text. Can someone tell me if this is my best option and if it would work for documents? Thanks!
