Does any one know of a good text to speech library. It needs to be open source and provide C API?

PS: I've already done a search, but I'd like recommendations from people who have actually used these APIs

Festival is the devil. Took me all day to get it installed on OS X and to try out different voices. All the voices are really crappy quality. Sucks.

I have used flite in an embedded server. It has a small footprint and comes with a single voice

eSpeak is another lightweight TTS. More robotty than Festival.

Festival is an open source text-to-speech system.

Stanford uses it for their Natural Language Processing class, and they have up-to-date instructions about installation on this cs224s homework page. Installation on Mac OS X requires a couple patches, which they've wrapped into a handy install script.

There are alternate voices you can use which sound noticeably better than the stock ones. You can find information on these voices in this forum post: How to setup more realistic voices in Festival. Those instructions are for Ubuntu, but the voices work with any Festival installation.
