The four coaches will be helped by Battle Advisors, who were revealed yesterday to be Paloma Faith, Cerys Matthews, Ana Matronic from Scissor Sisters and Dante Santiago.
During the Battle Rounds, the acts are forced to duet with their teammates on the same songs to prove to their mentors that they are worth keeping in the competition.
It is also suspected that The Voice UK's results shows at the live stages will end up going head-to-head with The Cube on ITV1, meaning This Morning co-hosts Holly Willoughby and Phillip Schofield will be having a ratings clash.
The Voice UK auditions continue on Saturday at 7pm on BBC One.
