How to adapt a vocal to a key ?

[Zefear]

Hi friends,

First of all, want to wish you a happy new year

I just finished a track and a singer sends me a vocal loop, which has a different key of my song.
I wanted to know how to adapt my vocal with the song I did (without use the transposition which make a chipmunk voice to my vocal loop ^^).

Hope you could help me !
Thanks

yeah, backwards : the song needs to be transposed to the singer's tonic

Yes but when I transpose, it make a "chipmunk" voice to the singer xD
Not the best :/

An other question, I've a vocal loop in a key and the lead vocal is an other key. How can I combine them ?
Thx
