| 摘 要： | 提出了一种新的语音识别方法,该方法综合了VQ和离散HMM算法,在每个状态通过用矢量量化误差值取代传统的HMM输出概率值来建立VQ-HMM.介绍了VQ-HMM,并通过非特定人汉语数码语音识别实验对其识别性能与传统的HMM作了相应的比较.实验结果表明该方法识别效果优于传统的HMM.，In this paper, a new speech recognition method was proposed, which integrated a VQ-distortion measure and a discrete HMM. The VQ-HMM uses a VQ-distortion measure at each state instead of a discrete output probability used by a discrete HMM. The VQ-HMM is described, and its speech recognition performance is compared with the conventional HMMs through the experiments on speaker-independent Chinese spoken digit recognition. The comparisons confirm that the new method over-performed traditional HMMs.

| Abstract: | In this paper, a new speech recognition method was proposed, which integrated a VQ distortion measure and a discrete HMM. The VQ HMM uses a VQ distortion measure at each state instead of a discrete output probability used by a discrete HMM. The VQ HMM is described, and its speech recognition performance is compared with the conventional HMMs through the experiments on speaker independent Chinese spoken digit recognition. The comparisons confirm that the new method over performed traditional HMMs. |
