Format and Stages

The show's format features four stages of competition: a blind audition, a battle phase, a live performance shows and the finals.

Stage 1 - Blind auditions

The first is the blind auditions, in which the four coaches listen to the contestants in chairs facing opposite the stage as to avoid seeing them. If a coach likes what they hear from that contestant, they press a button to rotate their chairs to signify that they are interested in working with that contestant. If more than one coach presses their button, the contestant chooses the coach he or she wants to work with. The blind auditions end when each coach has a set number of contestants to work with (such as ten in the U.K. version, sixteen in the U.S. version or sixteen in the Dutch version). Coaches will dedicate themselves to developing their singers mentally, musically and in some cases physically, giving them advice, and sharing the secrets of their success.

Stage 2 - Battles

The contestants who successfully pass the blind auditions proceed to the battle rounds, where the coaches pit two of their own team members against each other to sing the same song together in front of a studio audience. After the vocal face-off, the coach must choose only one to advance. If no specific winner can be identified the competition turns to a game of fate via a coin toss. In some versions, there are steals where opposing coaches can steal a contestant who was voted off by their own coach by pressing their button. As in the blind auditions, if more than one coach presses their button, the contestant chooses which coach they want. Each coach has a set number of steals (usually one or two).

In some versions, the winners of the battle rounds proceed to the knockout rounds. As in the battle rounds, coaches pit two of their own team members to compete against each other. This time, the contestants choose their own song to perform individually while the other watches and waits. After that, the coach chooses one to advance while the other is sent home.

Stage 3 - Live round

At the end of the knockout rounds, the strongest members of each coach's roster proceed to the live stage shows. In this final performance phase of the competition, the top contestants from each team compete against each other during a live broadcast. The television audience vote to save one contestant on each team, leaving the coach to decide on live television who they want to save and who will not move on. In the next round, the public chooses between the two artists left on each team, and the coach also has a vote that weighs equally with the public vote.

Stage 4 -Final

Finally, each coach will have his/her best contestant left standing to compete in the finals, singing an original song. The remaining contestants compete against each other in live broadcasts for the public's vote. With one team member remaining for each coach, the contestants compete against each other in the finale where the outcome is decided solely by public vote. From these four, one will be named "The Voice" and will receive the grand cash prize of a recording contract.
