So I decided to look into this a little and it looks like there are a couple of bugs:
1. Any team weapon or vehicle they capture loses speech
2. Any open top vehicle they capture displays male partisans
The speech may require a bit of effort to fix. Yes the T-34 has a chance that it will be a female driver and it does have female speech, but a lot of that speech refers to the T-34 itself i.e. "T-34 moving out" "T-34 on the move" "T-34 ready for action". So it would require a bit more work than just attaching the current female voice to it. We would probably need to create a duplicate set of female vehicle speech and edit the lines so they no longer say T-34.
As for the open top vehicle issue I'd think it would just require a bit of a code, but I'm not a programmer and don't know for sure. I don't think it is something that can be done in the AE alone.
Like Imagelessbean said, thanks!
Sounds like the toughest part is voice acting, and one doesn't want an unpolished game where females suddenly change / lose voices because there are no lines.
Dang, gents, looks like we aren't getting this one unless we can find the original VAs for cheap / get new cheap VA.
