What I do is, i go and drag the acapella into Acid Pro then right click go to properties, then you'll see a "beat calculator" im not @ my studio so i can't be exact, but then you click start. it'll configure the down beat on the acapella or sample, then you click next, then listen to tha acapella and adjust it if you need to, then hit next again. and bingo you'll have the exact tempo. then you gointo FL and adjust the tempo for your beat.
Hope this helps, sorry if it dosn't.

Fruity Slicer has a beat analyzer i believe, that can just about give you an accurate tempo for the beat you wanna put under the voice. just open FL Slicer the load your sample and in the the right hand corner of the plugin window it should show you your BPM and beat total beat count. maybe that'll help you, im not completely sure though
it dosn't give you the EXACT tempo, it gives you a around-about tempo basically it guesses and tells you to pick one. lol, and why would you use the slicer for an acapella? lol.. anywho, jus look above @ my reply and if you have any questions PM me and i'll do it for ya, or help ya out.
