Will my voice sound better or worse on recording?

To practise for auditions, I record myself (on my iPhone 4s if that makes a dofference) singing and doing monologues. What I want to know if those recordings make my voice sound better or worse than how it actually is, or if that's how everyone else around me hears my talking/singing.

You're voice sounds the same on recording as in real life, to hear the way your voice really sounds put two books or dividers in front of your ears to stop the sound from vibrating up your jaw.

It will sound the same as you sing in real life, it might just sound weird to you, because you don't hear yourself completely. Try singing while cupping your ear because that will make the sound reach your better without recording.
