Yes, and it isn't open source, cross platform, or especially useful to anyone without a Mac. I for one can't use it because I don't have a Mac, and even if I did the built-in screen reader isn't perfect so I'm not sure how accessible it is. Also he didn't necessarily want actual audio output, only a means of which files could be created so users could make their own output if they wish. See my previous discussion about DAISY.

If you have a Mac it will read it for you. You can also customize the dictionary. There is also a programming interface if you really want high quality output, you can even create your own voices.
I personally have not played with it. It has been around for a long time.
