I like the voices overall. I can see the work that went into it for consistency and offering varied sounds to reduce the repetition. You can't please everyone with sounds and voices, so consistency and thoroughness are the main thing. I assume they will be tweaked over time to polish them up.
That being said, the ones that stuck out as not so good for me:
The dying noise that sounds like vomiting. Brings a really different image to mind when I hear it.
A lot of the female sounds are OK but sound kinda wimpy/whiny. Find a friend who does sports or martial arts, and the shouts will be much more 'serious'. Right now they sound like scared children trying to be tough.
I have no personal issue with the FU one, but I wonder if I had kids in the house... I know that a lot of us gamer geeks don't tend to imagine that family folks play these games, but they do, and it's probably unnecessary to make it harder for them. I know headphones exist but again, making things harder, more 'I have to hide this from the fam' probably isn't helpful to expanding the range of players.
ESPECIALLY LIKE: The death cough. I love the understatedness of that.
