Free voice acting for a good FOSS game

Free voice acting for a good FOSS game

I'd be glad to voice act for a good & FOSS game, but this game should be getting somewhere nearer to betta, not just a raw idea (I have a raw 200-pages idea of my own :D). And this should be the game I like myself playing & voicing over.

Here's an example sketch I made for Open Dungeons http://opengameart.org/content/voice-acting-sketch-open-dungeons . And another one for STK http://opengameart.org/content/airport-announcement-voice-acting-stk
I fluently speak English, Russian and Ukrainian.

It's free, but the project [b]must[/b] be interesting for me. I prefer CC-BY-SA, but it's discussable.
