The Voice knockout rounds will be going a little differently in season 12 compared to the past few editions.

The Voice season 12 Battle rounds are over, with 32 artists now advancing to the Knockout rounds. Each of these artists will perform an individual song against another artist, with their coach having to decide who advances to the live shows. Of course, the other coaches also have the opportunity to steal losing Knockout artists.

While this format is staying the same, one major element is not. As teased in Tuesday night's promo for next week, there will be no key advisor for the Knockouts. Typically, the show brings in a music superstar (or superstars) to advise the contestants, like Taylor Swift in season 7, Rihanna in season 9 and Tim McGraw and Faith Hill in season 11.

Instead, the artists will get one-on-one training with their respective coaches. Adam Levine, Gwen Stefani, Alicia Keys and Blake Shelton are all shown coaching their artists in the promo for next week's episodes. It remains to be seen if this solo coaching will provided different results than the usual format.

Additionally, the artists will get to watch each other's rehearsals for the first time.

The season 12 Battle rounds featured major stars advising the artists and helping the coaches. Levine had Oscar and Grammy winner John Legend, Stefani had worldwide vocal powerhouse Celine Dion, Keys had beloved entertainer DJ Khaled and Shelton had one of country's most popular artists, Luke Bryan.

The Voice has signed some advisors on as coaches in the past. Pharrell Williams advised Usher's team in season 4, Keys advised Williams' team in season 7 and Miley Cyrus advised during the Knockout rounds in season 10. It's very possible that we could see Legend, Dion, Khaled or Bryan becoming coaches themselves in the future, considering their respective popularity in the U.S. and around the world.

The Voice airs Mondays and Tuesdays at 8 p.m. ET/PT on NBC.
