text-to-speech on the iphone

surprising how little there is out there. i'm probably not looking in the right place. a number of people got flite running: http://artofsystems.blogspot.com/2009/02/speech-synthesis-on-iphone-with-flite.html http://www.voxtrek.com/ http://www.cmang.org/ http://www.embiggened.info/vocalizer.html some of them have itunes links to buy the software, but they don't seem to be active. one is a navigation system, another is just flite with a little gui icing.
