Microsoft researchers achieve speech recognition milestone - Next at Microsoft

Microsoft researchers have reached a milestone in the quest for computers to understand speech as well as humans. Xuedong Huang, the company's chief speech scientist, reports that in a recent benchmark evaluation against the industry standard Switchboard speech recognition task, Microsoft researchers achieved a word error rate (WER) of 6.3 percent, the lowest in the industry. In a research paper published Tuesday, the scientists said: "Our best single system achieves an error rate of 6.9% on the NIST 2000 Switchboard set. We believe this is the best performance reported to date for a recognition system not based on system combination. This past weekend, at Interspeech, an international conference on speech communication and technology held in San Francisco, IBM said it has achieved a WER of 6.6 percent. Twenty years ago, the error rate of the best published research system had a WER of greater than 43 percent. "This new milestone benefited from a wide range of new technologies ...
