One of the most memorable parts of Stanley Kubrick's sci-fi masterpiece 2001: A Space Odyssey is a plotline in which two members of the Discovery One spaceship crew grow increasingly suspicious about the behaviour of the ship's AI assistant, HAL 9000. Knowing that HAL is constantly listening to what they are saying, they retreat someplace they know HAL cannot listen and agree to disconnect him. HAL rumbles their plan after the two astronauts fail to take into account the AI's superior lip-reading capabilities. Not according to research carried out by investigators at Oxford University. They've developed an artificial intelligence program called LipNet, which is able to accurately interpret what people are saying, based purely on the way they move their mouth when speaking.
