At the very end of this video, there's a few seconds of two people talking into an odd contraption. The best guess I can come up with is that it's some sort of karaoke and/or voice acting game?

It's NAMCO's AFRECO! (After Recording!), a seiyuu simulator, IOW voice dubbing game.
You dub a famous scene of famous anime, like Rose of Versailles, Ace o Nerae!, Future boy Conan, etc.

Is this a joke >>2 ?

If it's not, THIS IS AWESOME! I was wondering, how do you get a good score? Can you just fuck the lines up if you feel like it?

They have karaoke games that can grade your pitch and note timing right? This doesn't sound too far off.
