UNSUPERVISED ADAPTATION OF A LARGE VOCABULARY AUTOMATIC SPEECH RECOGNIZER

A technique for improving the recognition accuracy of a speech recognizer includes deploying the speech recognizer, wherein live input data is received by the recognizer as an input for a given speaker independent adaptation algorithm associated with the speech recognizer. The algorithm enhances the...

Zusammenfassung:	A technique for improving the recognition accuracy of a speech recognizer includes deploying the speech recognizer, wherein live input data is received by the recognizer as an input for a given speaker independent adaptation algorithm associated with the speech recognizer. The algorithm enhances the accuracy of the speech recognizer without human supervision. This technique is particularly suitable for adapting a large vocabulary ASR engine.
