METHOD FOR IMPROVING PERFORMANCE OF SPEECH RECOGNITION IN TELEMATICS ENVIRONMENT AND DEVICE FOR EXECUTING THE METHOD

摘要

A method for improving speech recognition performance under telematics environments and an apparatus for performing the method are provided to minimize an error that a recognition result is recognized again by removing a recognition result receiving a negative response about system confirmation of user's speech from a re-recognition process. A wide POI(Point Of Interest) is inputted if recognition of an inputted detailed POI fails. A POI network associated with the wide POI is activated. A POI having the highest similarity with the detailed POI which is inputted again is searched from the POI network and a searched result is provided as a recognition result. When the POI network associated with the wide POI is activated, an N-best POI result of the inputted wide POI is generated and a POI network corresponding to the N-best POI result is activated.
