You can't set a recorded voice to set as ringtone.
You can't set a song as a message tone. The only tones you can send in a message are from your sounds. Sounds are a special format, just as pic, music, ringtones etc.
You can record your own sounds, but unfortunately they come out fuzzy and don't sound real good.
You want to make ringtones and sounds for your phone follow this below:
You will need
1. Phone with usb cable
3. Bitpim software
Here is how you can make your own Ringtones, Sounds etc.
