It's not a range test demo. It's a real conversation with real people who aren't prone to melodrama. As mentioned in the video by Lex, it's the subtleties that make all the difference. I'm astonished with the accuracy of the blinking, mouth movements, subtle cheek variations, etc. It seems more accurate than the realtime feed from my webcam. The only thing I wouldn't like about it is having to wear a headset in order to experience it.
