Microsoft AI Beats Humans at Speech Recognition

Microsoft's Artificial Intelligence and Research Unit earlier this week reported that its speech recognition technology had surpassed the performance of human transcriptionists. The team last month published a paper describing its system's accuracy, said to be superior to that of IBM's famed Watson artificial intelligence. The error rate for humans on the widely used NIST 2000 test set is 5.9 percent for the Switchboard portion of the data, and 11.3 percent for the CallHome portion, the team said.
