Jessie J, Sir Tom Jones, Danny O'Donoghue and Will.i.am will be competing against each other on the BBC talent show, which is set to have some new twists this time round.
The show's ratings dropped during the first series following the end of the "swivel chair" rounds.
An 11-date tour featuring performances from the finalists was cancelled, due to poor ticket sales.
Leanne Mitchell, who was mentored by Sir Tom won the show last year, but a download version of her debut single failed to make it big in the charts.

Jessie J has postponed her entire sell-out arena tour because she wants to spend more time recording her album, she announced today.
The chart-topping singer had been due to start her 17-date tour in March.
She wrote on Twitter and her website, "I would like to be the first to tell you that my nice to meet you tour has been rescheduled to later next year".
"I am honestly truly sorry but I hope you all can understand that it's just because I would like to take more time to finish my new album. I promise to make the show my biggest and best ever and cannot wait for you all to hear my new songs", she continued.
Jessie J added that all tour tickets will be valid for the new dates in October and November 2013.
Pop star Jessie J has dismissed a claim she is a lesbian who has hidden her sexuality to avoid putting off fans.
The Voice mentor and coach says the suggestion, which was published in a new unauthorised biography about her earlier this month, was "untrue".
The singer took to Twitter to dismiss the story and author, Chloe Govan's claim.
She wrote: "It's funny how many people I've dated/slept with that I've never even met, according to the tabloids.
"BUT what's that?! whispers, because its a secret I'm really a lesbian?! Ha! Thanks for writing yet another boring untrue story."
She then went on to list the names of other stars with whom she has reportedly been linked with, adding: "#noneofitstrue".

"I am lost for words. All I can say is my thoughts, love and respects are with the family and children of the man who attended the blackberry gig last week who sadly lost his life this morning. So sad..."
Jessie J says she would love to collaborate with Rihanna at Wireless Festival and plans to ask the international star to sing Do It Like A Dude with her on stage.
The British singer also says "it's exciting" collaborating with her fellow Voice coaches and that it would be "brilliant" if they could get Tom Jones to rap.
