Presented with a group of "mystery singers"[a] identified only by their occupation, a guest artist must attempt to eliminate bad singers from the group without ever hearing them sing, assisted by clues and a celebrity panel over the course of three rounds. At the end of the game, the last remaining mystery singer is revealed as either good or bad by means of a duet between them and one of the guest artists.
Rounds
Each episode presents the guest artist with a group of people whose identities and singing voices are kept concealed until they are eliminated to perform on the "stage of truth" or remain in the end to perform the final duet.
Visual round
The guest artist is given some time to observe and examine each mystery singer based on their appearance. Afterward, a muted video of each mystery singer that reveals only 0.3 seconds of their singing voice is played as an additional hint.
Lip sync round
Each mystery singer performs a lip sync to a song; good singers mime to a recording of their own, while bad singers mime to a recording by someone else.
Evidence round
A proof of each mystery singer's singing ability (i.e. photo, video, certificates, etc.) is shown on the screen. Good singers have own evidences, while bad singers had their evidences fabricated.
Note
^For the show's gameplay changes, based on playing time of an episode:[2]
The number of mystery singers are set to six (eps. 7 and 9) or seven (for the rest of episodes).
Background
In a joint agreement with CJ ENM, Jiangsu Broadcasting Corporation formally acquired the rights to produce the first locally-licensed adaptation of I Can See Your Voice in June 2015,[3] including with production duties assigned by Eslite Media, Hua Chuan Culture, and Inly Media Company.[4][5]
Two months after the formal announcement, CJ ENM accused two (locally unlicensed) programmes, God of Songs by SZTV and X-Singer by Beijing TV,[6] of plagiarism. They have also implement on modified game mechanics, strikingly similar to the original format of I Can See Your Voice without having permission from the said company.[7]
