NOISE ADAPTIVE TYPE VOICE RECOGNITION DEVICE AND RECORDING MEDIUM RECORDING NOISE ADAPTIVE TYPE VOICE RECOGNITION PROGRAM

摘要

PROBLEM TO BE SOLVED: To realize a voice recognition device capable of recognizing voice rapidly in real-time and excellent in a robust property even under a noise. ;SOLUTION: This device is a noise adaptive type voice recognition device provided with an input part 1, an acoustic analytic part 2, a probability noise model storage part 6, a noise adaptive probability acoustic model storage part 7, a noise detection part 62, a probability noise model selection part 4, a model switch part 5 selecting a noise adaptive probability acoustic model from the noise adaptive probability acoustic model storage part 7 and imparting it to a recognition part, and the recognition part 3. At this time, the device is provided with an adaptive model index 8 relating a selected probability noise model with the selected noise adaptive probability acoustic model.;COPYRIGHT: (C)2000,JPO
