Voice distortion

the track I once recorded is now slowed and my voice is deeper I just want to return it to the original faster track any help?

In Preferrances Setting you can select how the “clock” is set for n-Track. You can use the computer clock or a clock from an audio interface or perhaps you on board sound card. It is preferable to use an external audio interface to record as the clock that the computer uses may slow down as the load on the computer changes.
If you setting is for internet see if it recognizes your sound card. The best solution is to get an audio interface and use that clock. If you get a USB run interface limit other things that use USB.
