In conjunction with my Playable Tusken mod, I've added a booster pack of soundsets that includes a Tusken voice. Now when playing as a Tusken, you won't sound like a human. There are four new alien voices added this time around (Bith/Ithorian, Hutt, Jawa, and Tusken). The link is in the first post.
The soundsets require the Kotor Savegame Editor in order to change your PCs voice.
Oh, and could someone please change the name to "[K1] PC Alien Species Soundsets
"? Thanks. I think that'd be a little more descriptive, and I don't have the room in the title to say "Make your playable character sound like an alien with soundsets".
