The Papist:
OK, some minor corrections:
- "u" is not pronounced like...hell, I can't find a good example

like the word "you". More like double o in "mood", but shorter. Vowels in general I think are pronounced quite short and bright and sharp in khuzdul. And R is the russian sound "R", if you have the movies with you, you can check how some actors pronounce it right and some don't. For instance Frodo who is a hobbit with lesser knowledge

says Mordor like "mowdoh" where Gandalf and Saruman (both great voices and actors

) say it right with a sharp and sound "R".
- generally, the second attempts are better. I like the second Thorin. The first is a bit hissy with the "Th".
- Lac is drefed is ok, old english huh.

- my problem with most of them: They're warcries, should be shouted out more. Still recognizable and understandable, but you could put more emotion and anger in them. Especially since they're dwarven. I know it's hard without a pro-mike, but I think here's it's a matter of practice. The second Thorin is almost there

edit: also if you have the extended versions, check out Gimli's "Ash Kaqwi Durugnul" in Lorien
