Abstract:

In this paper, a speech recognition and verification method is presented based on the integration of likelihood and likelihood ratio. Speech recognition and verification is unified in one-phase framework. In the process of decoding, likelihood ratio is combined with likelihood to get the combination score for searching the final results. Experimental results show that the false-alarm rate is significantly reduced, with only a slight loss in the accuracy rate.
