Machine learning could be the answer to helping millions of hearing-impaired people read what's being said in the world around them. Researchers at Oxford University and Google DeepMind have developed an artificial intelligence system trained on thousands of hours of BBC video broadcasts that far outperforms a professional lip-reader. The human lip-reader, who's provided lip-reading services for use in court, was shown a random sample of 200 videos from the BBC test set and correctly deciphered less than a quarter of the spoken words. The AI system was able to decipher half of the words from the same set, the researchers say in a new paper. New Scientist also reports the professional was only
