I've seen the room but that only works because it completely surrounds and entraps the sound, a microphone only gets hit by some of the vibrations of you talking and the rest is still audible around you, so it wouldn't be able to cancel it out.
Also the walls of the room are like a meter thick so it would be a very big microphone.
Also you could just like, not sing?

you can cancel out sound by sending out opposite sound waves but it won't work because you have to receive the sound before you can send out matching opposite sound waves and then it's too late

This. Sounds cancelling out one another by having so much sound ontop of another to sound like nothing. It's been done before.

The device would copy the sound that went into it and play it back 180° out of phase to silence it.

Doesn't quite work that way though, you're going to have some extra sound from that.
