 In the second stage, called the battle phase, coaches have two of their team members battle against each other directly by singing the same song together, with the coach choosing which team member to advance from each of individual "battles" into the first live round.Within that first live round, the surviving four acts from each team again compete head-to-head, with public votes determining the best of four acts from each team that will advance to the final eight, while the coach chooses which of the remaining three acts comprises the other performer remaining on the team.In the final phase, the remaining contestants compete against each other in live broadcasts.
