The Voice (American season 12)

The twelfth season of the American reality talent show The Voice premiered on February 27, 2017 on NBC. Adam Levine, Alicia Keys and Blake Shelton continued as coaches with Gwen Stefani returning after a two-season absence. Carson Daly continued as the show's host.

This is the first season iTunes bonuses were awarded for duet performances (seen in semifinals and finals), in addition to previous bonuses which were awarded during the live shows (including the finals which was intact since season 10).

Chris Blue was named the winner of the season, marking Alicia Keys' first and only win as a coach and the second female coach to win in the show's history, following Christina Aguilera. With Blue's win being the third African-American male winner. For the first time, the last artist (and also the first artist receiving only one chair turn by default) selected in the Blind Auditions went on to win the entire season.

Coaches and hosts
There was a change in the coaching panel for the twelfth season. Gwen Stefani returned to the panel after a two-season hiatus, replacing Miley Cyrus along with returning coaches Adam Levine, Blake Shelton, and Alicia Keys while Carson Daly returned for his 12th season as host.

This season's Battle advisors were: John Legend for Team Adam; Celine Dion for Team Gwen; DJ Khaled for Team Alicia; Luke Bryan for Team Blake.
