The fifth season of the Thai television mystery music game show I Can See Your Voice Thailand premiered on Workpoint TV on 13 October 2021. In celebration of the show's fifth anniversary, it is subtitled as I Can See Your Voice Festival because of the monicker that applies on a random-specific theme, affecting their lineup of mystery singers.
Gameplay
Format
According to original South Korean rules, the guest artist(s) eliminate mystery singers at the end of each round, with the last remaining mystery singer ended up in a duet performance by one of the guest artists.
Rounds
Visual round
The host is given three "keywords" depending on the mystery singer's identity. Afterward, five different voice snippets from the muted video are being played.
Introduction round
Each mystery singer self-introduces to guest artist and panelists. Good singers are telling the truth, while bad singers are allowed to lie.
Lip sync round
All of mystery singers perform their lip sync on separate phases, with the good singers' recordings first, and then the bad singers last.
1. Talent round (episodes 1—8)
The guest artist must describe one of the mystery singer's other talents, except "singing" itself. This may not be related to the "stage of truth", but depends on their identity.
2. Evidence round (episodes 9—18)
The guest artist must assign three "mystery songs" to one of the mystery singers of their chosen. Afterward, they must react toward that song.
