The artists get to choose their own songs in this round, although they continue to get help and advice from their respective coaches.
At the conclusion of the performances, coaches would decide which one of each pair gets to advance to the next round.
Based on the original The Voice of Holland, the concept of the series is to find currently unsigned singing talent (solo or duets, professional and amateur) contested by aspiring singers, age 15 or over (reduced to 13 since season 12), drawn from public auditions.
The series employs a panel of four coaches who critique the artists' performances and guide their teams of selected artists through the remainder of the season.
They also compete to ensure that their act wins the competition, thus making them the winning coach.
A new element was added in season three; coaches were given two "steals", allowing each coach to select two individuals who were eliminated during a battle round by another coach.
The Knockout Rounds were also introduced in season three.
The coaches' chairs are faced towards the audience during artists' performances; those interested in an artist press their button, which turns their chair towards the artist and illuminates the bottom of the chair to read "I want you." At the conclusion of the performance, an artist either defaults to the only coach who turned around, or selects his or her coach if more than one coach expresses interest.
In the 14th season, a new twist called "Block" is featured, which allows one coach to block another coach from getting a contestants.

With the exception of Season 7 and several other rare cases, the show has begun with a cold open that ends with someone breaking character and proclaiming "Live from New York, it's Saturday Night!
