We proposed a new speech recognition method by the integration of the VQ

HMM and an unsupervised speaker adaptation algorithm

it comply a VQ-distortion measure at each state instead of a output probability used by a traditional HMM

and uses an fuzzy adaptive VQ algorithm to alter the codewords for speaker adaptation.In this paper

the new combined method is compared with CHMM by the task of speaker-independent Chinese spoken digit (isolated/connected) recognition

and the results confirmed that the good performance of the new method and superior to traditional CHMM.
