The Voice of Bulgaria

The series consists of three phases: a blind audition, a battle phase, and live performance shows. Starting season 4, Knockout round is implemented for the total of four phases. Four judges/coaches, all noteworthy recording artists, choose teams of contestants through a blind audition process. Each judge has the length of the auditioner's performance (about one minute) to decide if he or she wants that singer on his or her team; if two or more judges want the same singer (as happens frequently), the singer has the final choice of coach.

Twists in blind auditions was then added. Starting season 4, when the contestant doesn't manage to turn around any coach of their chairs, the contestants will automatically leave the stage and the coaches' chair will remain unturned and they can't meet the contestant. In season 6 onwards, new twist is added to give coaches new power, the "Block" button. A new powerful button with the name of other coaches which coaches can hit any of those three new buttons to prevent another coach nabbing the contestant on its team. Coaches is entitled only one "Block" for the entire blind auditions (raised to two in season 8) In season 7, when the blocked coach tries to turn around for the contestant, the chair of the blocked coach won't turn around. However, the blocking coach will lose the opportunity to block again if the blocked coach does not pressed his main red button or turned around.[1]

From season 8 onwards, coaches has the freedom to select unlimited number of contestants for their respective teams. However, the number of contestants on the team will be finalized by cutting them down to 14 contestants per team by selecting randomly by their coach to proceed into battle rounds.

Each team of singers is mentored and developed by its respective coach. In the second stage, called the battle phase, coaches group its team to two or three ( which happened on season 7 ) 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 four individual "battles" into the next round, the Knockout rounds. However, starting season 3, new power is added to the coach during the phase, the "Steal". Each coach is given two (one in season 6 and season 8) steals to save the artist from another team who lose their respective battle.

Knockout round is implemented starting season 4. The participants who remained after the vocal battles are grouped by the mentor into trios. Each artist had to sing in order to convince their respective coach to pick them for the Live shows. Each artist will decide on what song they will sing. After the performance, the coach would decide who to advance to the Live shows. In season six, rules for the Knockout changed. Three chairs is placed on the stage to be seated by contestant. After the artist performing the song of its choice, the coach will decide if the artist will going forward to the next round by giving a chair or the artist will go home by not giving chair. At the end of this round, three artists per team will moved to the Live shows.[2]

Within that first live round, the surviving four acts from each team again compete head-to-head, with public votes determining one of two 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 (Final 24) compete against each other in live broadcasts. The television audience and the coaches have equal say 50/50 in deciding who moves on to the final 4 phase. With one team member remaining for each coach, the (final 4) contestants compete against each other in the finale with the outcome decided solely by public vote.
