| 摘 要： | 本文提出了一种新的语音识别方法,它综合了VQ、HMM和无教师说话人自适应算法的优点,在每个状态通过用矢量量化误差值取代传统HMM的输出概率值来建立FVQ/HMM,同时采用基于模糊矢量量化的无教师自适应算法,来改变FVQ/HMM的各状态的码字,从而实现对未知说话人的码本适应.本文通过非特定人汉语数码(孤立和连续数码)语音识别实验,把该新的组合方法同基于CHMM的自适应和识别方法进行了比较,实验结果表明该方法的自适应和识别效果优于基于CHMM的方法.

| Abstract: | 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. |
