I Can See Your Voice Thailand

A guest artist is presented with a group of seven "mystery singers". Some of them are bad singers, and some are good. The artist must attempt to eliminate bad singers from the group by guessing who they are without hearing them sing. They get assistance from clues and "celebrity panelists" over the course of four rounds. The guest artist will eliminate one to two singers at the end of each round and then proceed to perform on the "stage of truth". At the end, the winning mystery singer is revealed as good or bad by means of a duet with one of the guest artists.[1]

The Thai version has two gameplay formats:

• Original format

Under the original format, the guest artist(s) can eliminate one or two mystery singers in each round, and the last mystery singer(s) standing will perform a duet.

• Versus format (seasons 3—4)

Under the versus format (adopted by Giọng ải giọng ai), both guest artists can eliminate one mystery singer each in the first two rounds, and then both can choose one mystery singer each to perform a duet with in the third round.

The winning condition implies to each mystery singer chosen by guest artist that has been performed a duet separately, if:

• One guest artist had chosen a "good singer" and another one had chosen a "bad singer"; or
• Both two guest artists had chosen a "good singer" or a "bad singer".
