Tap tempo is it for acapellas if you don't know the tempo. You may have to cut a slide a piece here or there. Just because you have the correct tempo match does not mean it will fall in correctly with the groove throughout unless you made the music specifically to go with the vocals.
Once you find the general tempo you can change the tempo of the acapella to any bpm you want without distortion/artifacts. It's done everyday, all day by sample producers, for remixes, and by DJs. Every daw has elastic audio/time stretching functions for this. I have gone as far as 20 bpm up or down with elastic audio/x-form in pro tools without artifacts.
