Digital Spy caught up with the show's coaches and hosts to get the lowdown on the new-look format, 'killer songs' and 'steals'.
The stars on series two....
Tom Jones: "The first series, we were treading fresh water and it worked really well. But this series, we were more sure of ourselves. My only concern was that the four coaches had to be the same. It wouldn't have been the same with someone else."
Reggie Yates: "People have seen it now, so the thought of getting closer to these coaches means much more now. They want to hang out with Jessie, they want to be in a studio with will. It means a lot more now to these contestants."
Holly Willoughby: "The nature of a show like this is that it will be emotional, challenging, and some people will wear their hearts on their sleeves."
Jessie J: "One thing I learned last year is that my eyes are my eyes, my ears are my ears and my heart is my heart. I have to judge on my feelings and emotions and I'm really honest this year. Really honest. I can't listen to the other coaches or the audience screaming out names."
On the new steal twists:
will.i.am: "I think the steals are amazing. They added a whole new level of competition that we have to be mindful of when it comes to who we want to keep. Last year I didn't have to worry about Danny snatching my acts. Who you get rid of this year can possibly come back to hurt you. You have to think about that."
Danny O'Donoghue: "The steals are great, because last year there were some times where a coach may have got it wrong. And this gives us all the chance to make sure that doesn't happen and we can shout up and shove it back in the other coach's face and say, 'You got this wrong'."
On the new Knockout Killer Song round.....
Reggie: "It's the point in the show where what they sing counts. It turns up some really dramatic moments."
Tom: "It gives them a chance to be the best they can. Or at least the best that they think they are."
Jessie: "It's about people revealing who they are as artists. You suddenly hear what they want to sing and it's very interesting to hear their voice in terms of how they want it to be heard, rather than the covers and songs that have been picked for them."
Holly: "It puts the power in the act's hands. So many times on these shows, you hear 'I don't like the song' and 'It wasn't fair'. This tells them to stand up and be counted as an artist. They should know who they are and what direction they want to go in, it's their opportunity."
On how it's about more than 'the voice'....
Jessie: "The first round is totally about 'the voice'. But then naturally you have to take into consideration their age and dealing with the press. People are already talking about it and it's not on TV yet. If you've not experienced it, it's scary. Everyone who goes through can sing. But you also have to take into consideration how people handle themselves, how much they work and how they look after their instrument. It's a big jump."
Tom: "It's also about how they handle themselves on stage under the pressure. You see that in the Battles. You hear their voices backstage, but it can come down to how they handle themselves on that stage, under pressure and in front of all those people. You have to wait for the last minute to make your judgement."
The Voice is back for its second series on March 30 at 7pm on BBC One.
