"These amazing artists are the perfect inspiration for our contestants to look up to as they begin their journeys from 'voices' to true artists — and any hopeful singer would be incredibly lucky to have either one as their coach," network executive Paul Telegdy said in a statement.
The Voice will feature four famous musicians (including Grammy winners Green and Levine) who will select singers to mentor. Two other judges will be named later.
Once the teams are created, the coaches will bring in their songwriters and producers to help work with their groups. Viewers will decide who wins a recording contract and $100,000.
"Being a coach on The Voice is a substantial responsibility, and I take it with sincerity and distinction," Green said.
Said Levine: "I look forward to working with these singers and helping them push forward throughout the competition to make their musical dreams become a reality."
The Voice premieres Tuesday, April 26 at 9/8c on NBC.
