Play special sounds when different chat events happen
Chatterbox supports English, French, German, Italian, Portuguese, and Spanish interfaces
Sounds can be limited by sender so you are not overwhelmed
Channels can be disabled, or use internal or even custom external (OGG) files
Open channels (Says, Whispers, and Yells) can be limited to Friends and NPCs, etc.
New sound "picker" makes using built-in WoW sounds easy
Each "channel" can have a dedicated sound
