How do I turn off voice notifications on my LG Shine?

I was playing with the settings on my phone last night and came across an option I had not seen before. By activating this option, prior to the ringer the phone will announce that there is an incoming call/message and state who it is from.
That being said, I thought I would try it out. Now, I can’t figure out how to turn it off, and have gone through all the phone settings. Can someone please help me?
