“The Voice” is beefing up its professional talent roster, as Ryan Tedder of OneRepublic joins the NBC series as its first-ever in-house producer and songwriter.

Tedder, who served as an adviser this season on “The Voice,” co-founded OneRepublic and supplies the vocals for tracks including “Apologize,” “Stop and Stare” and “Good Life.” As “The Voice’s” in-house producer and songwriter, he will work with the final three artists this season, penning original songs stylized for each contestant.

The finalists will perform the original songs at the conclusion of the season on Dec. 17. (Like all performances on “The Voice,” the tracks will then be available for download immediately following the episode broadcast on iTunes.)

Singing competitions including “American Idol,” “X Factor” and “The Voice” are typically known for having contestants cover songs from major artists, save “Idol’s” coronation songs for finalists, which have, at times, gone on to be chart-topping hits. (Phillip Phillips’ “Home” was on regular rotation during NBC’s telecast of the 2012 Summer Olympics.) The addition of Tedder as an in-house songwriter — should he stick around for “The Voice’s” upcoming seasons — could mean more original material for the show’s contestants, and earlier on in the season.

“Ryan is a brilliant songwriter and on the forefront of today’s music scene. His contributions to ‘The Voice’ will be invaluable in both his work with our artists and in creating a song that will capture the essence of our show,” said Paul Telegdy, head of NBC’s alternative department.

In addition to being the lead vocalist for OneRepublic, Tedder has produced songs for artists including Adele, Beyonce, Leona Lewis, Carrie Underwood and Maroon 5, the band led by “Voice” coach Adam Levine.
