Permanent panelists Cheryl Hines and Adrienne Bailon-Houghton and a rotating panel of guest celebrity detectives must help one contestant tell the difference between good and bad singers, without ever hearing them sing a note. With $100,000 on the line, each contestant will attempt to weed out the bad "Secret Voices" from the good, based on a series of clues, interrogation, and lip synch challenges. In the end, the singer whom the contestant picks will reveal if they are good or bad in a duet performance with musical superstar Michelle Williams, resulting in an amazing musical collaboration - or a totally hilarious train wreck.
