Great companion to goodreader
Yes it does work with PDF, but it basically copy and paste the text into its own interface. For me I work very well to use this app with good reader (annotations, bookmarks, native PDF viewing ...)
Must pay each voice 0,99$ for offline usage.
Bottom line : Good voice quality, works in the background, and use native "iPod controls".
A good value !
