All it does is mute Unta's emotes. Really.

So you finally got the Mighty Caravan Brutosaur and are happy to use the auction house wherever you please... And after a short while you're super annoyed by Unta's quotes? You're having violent thoughts when someone just mentions "Have anything ancient to trade?" or "If you find anything exotic..." to you?

Then this addon is for you!

Basically, it just registers itself when you're entering the world and uses the Game's MuteSoundFile API to suppress playback of the appropriate sound files (by ID). The IDs were thankfully provided by bhbob in this comment - thanks, mate!
