The reveal
Your attempt gets reversed again. If you nailed it, you'll hear the original song.
Tip: short phrases with clear vowels work best. Try "Happy birthday to you" or the chorus of your favourite song.

What does a reversed voice sound like?
Speech played backwards sounds like a strange foreign language. Consonants that normally start with a sharp attack, like "t" or "k", fade in instead, and vowels glide the wrong way. That's why reverse speech is so fun to listen to, and so hard to imitate.
Why is reverse singing so hard?
To sing a song backwards you have to reproduce sounds your mouth never normally makes, in the right order and at the right pitch. The reverse audio challenge became popular on TikTok because even familiar songs come out hilariously wrong on the first try.
