If someone were to combine MauveBib's Sagdoll mod and Chris' Construct mod, you'd have just that, basically.

Sin added a hacked-up M$ TTS library hookup in a 2001 patch , it was wacky listening to the chatlines in multiplayer

UT2004 also has speech on text.

problem is, most TTS libraries are non-Free, and are GPL incompatible.

And the few GPL ones don't have support for Windows. Yeah, I know. I already researched about this. Still, it would be a really cool feature.

On Windows use SAPI.

It was my first idea, but then I realized that would be a PITA to get other voices besides the standard.
