LG VX-8500 Chocolate

I dont know if this is an easy fix or not but i cant figure out how to get rid of the computer voice that says "verizon wireless" before my ringtone comes on. also i cant make the phone stop saying in a computer voice all of the settings, like if i go to voice commands and i hit on menu or anything it will say "menu" its annoying and i dont want my phone to have any sounds except for the ringtone. thanks
