| Abstract: | This paper describes an implementation of the minimum recognition error training for continuous Gaussian density HMM. We defined the misrecognition measure directly by discriminant function for the minimum recognition error training of CHMM. Also a minimizing method of the discriminant error function for CHMM training was investigated. The experiment on speaker independent continuous speech recognition of Chinese shown that the proposed method is effective. |
