You hear your own voice very differently from everybody else around you. Not only do you hear the air vibrations your voice produces, but your ears also pick up the vibrations that run through your body(caused by your voice). This significantly alters the way you perceice your own voice compared to the people around you.
Hearing your voice recorded will sound very weird at first, not matter how good or bad the actual quality of the recording is, but it's something you have to get used to.
