Annoying bot that keeps talking

I'm having a big problem with some sort of bot on my sever, I download a few plugins. And now every time I log on I have to hear it talk and tell me every single thing people say, updates, and commands. Its really annoying and LOUD. How do I shut it off? I think its coming from the plugin Vault not sure.

Omg, thank you so much!! I had no idea there was such a thing on the game. ;-;
