UPDATE: I've re-posted a subtitled version.
This is a translation of the judges that was offered in YouTube comments. If anyone can offer corrections, or a better one, please do:
After the performance:
Judge A: You have been deceiving me all along. It's impossible.
Judge B: He's beautiful, isn't he? (Asks the crowd) I was dumbfounded when you started the second verse.
Judge C: Initially, I was certain that you were a transexual, but once you began singing, I was fooled to think that you were female. After you started the male verse, I should have trusted my gut feeling.
All judges gave the thumbs up.
Judge C: Continue the deception.
