LG CU500

When I brought the phone home from the store, the first time I dialed a number, the computer voice said the number. Then, after setting my ringtones, and other defaults I liked, I no longer have the voice saying the numbers. Does anyone know how to get these tones back? The manual for this phone really stinks! It doesn't tell really how to do anything.

Also, how do you set a recorded voice as a ringtone?

Thanks for your help.
