I Can See Your Voice: Vietnam (2016)

The guest artist(s) must attempt to guess six contestants who are 'good singers' (skilled vocalists) and who are 'bad singers' (tone-deaf vocalists) without hearing them singing. They also help with a group of panelists under the Tone-deaf Detective Team (also called SING-vestigators). After they eliminate one to two contestants in each round, they reveal their singing ability on the Stage of Truth. For the groups, all members must be able to sing to be considered as 'good singers'. If one member of the group can't sing well, even while the others can sing, they're all considered as 'bad singers'. The last person standing will get to sing alongside the guest artist(s). If the winner is a 'good singer', they will give a chance to release the song alongside the guest artist(s) as a digital single. If the winner is a 'bad singer', they receive nothing. On the 5th season's first episode, the winning skilled vocalist received a pair of specially-made microphones.
