Hi Stellina,
If one is singing into the mic, and the accomp track is playing and heard in speakers (not using earphones), one can not avoid picking up some sound from the speakers.
So, you'd need headphones. If not, try lower speakers volume, and sing and cover the mic by being close to the mic.
But with headphones, you can get total voice on one track separate, as explained above, and there are other ways, but they would depend on your sound card, or card interface.
One simple way (using headphones): the backing track is already recorded in an audio track. It is meant to only play. You hear it from the headphone jacks. You plug your mic in the mic port, for a normal mic, not for usb mics, though. Set the input of a second audio track as mic and enable that track for recording. So second track only records from mic while you can hear the backing track. You might need to push the "Echo" button of the Mic track..That's colored green, and is on the right side of the [R] record button, and looks like this [.>>], so as to hear also your voice from the earphones, along with the track.
I really think in your question you are not really asking about singing without hearing the accomp track, though. You kind of have to hear it, so to sing along, right? So you'd have to use headphones, if what you mean is to keep the voice separate, and not feed from speakers into mic, seems to me.
Good luck.
