i Speak It by Zapptek
I wish I were a Mac User - but I am locked into our Windows PC world in our school districts. As I have been exploring the text to speech options within the iPhone world, I have been getting great tips from readers. The i Speak It app from Zapptek looks promising - if you own a MAC.
It converts files to audio and then is a companion to your iPhone or iTouch. It converts Word docs, PDF, Pages, RTF, Appleworks, Text files and HTML files. It converts those to Mp3/AAC track files through iTunes so you get the text as a lyric as you listen, to follow along on screen (that's what it says...dunno exactly how that works).
Sounds pretty cool - but I can't test it on my PC. If anyone has it, let us know what you think.
