Common Sense Speech Recognition

Henry Lieberman, a research scientists at MIT's Media lab investigate improving speech recognition by using a database of common sense facts. The Open Mind Common Sense Project database contains more than 700,000 facts that have been accumulated over the past 4 years or so and is used to help choose among recognition results returned by the speech recognizer with "close" confidence scores. They report a 17% reduction in errors and a 7.5% improvement in dictation time when dictating speech in topical areas for which the database contains facts.
