Who's better at reading lips – humans or AI?

HAL 9000: I know that you and Frank were planning to disconnect me, and I'm afraid that's something I cannot allow to happen. Astronaut Dave Bowman: Where the hell did you get that idea, HAL? HAL 9000: Dave, although you took very thorough precautions in the pod against my hearing you, I could see your lips move. A bit behind schedule – if you don't recognize that movie dialogue, it's from Stanley Kubrick's 2001 – but computers are moving rapidly towards mastering lip-reading. But new research shows they're clearly outperforming humans, and improving fast. So if you've been captured on CCTV, with or without audio, it might soon be practical to decipher whatever you were talking about. Lip-reading has been an active focus of AI research for years.
