It'll be mostly text but I've got no problems in theory with occasional voice...my typing speed sucks & some days I'm gonna be too lazy to pound on the keyboard & would rather just save time by talkin'. The problem comes in when too many people will try to talk at the same time & no one can hear a complete thought...Plus there's the strong possibility that some of that talking will be closer yelling & irritate me to the point of shutting off my speakers.
