Abstract To solve the problems of short data and noisy recordings in pathological voice signals, this paper extracted some entropy feature parameters of pathological voice proposed in recent years, including sample entropy, multiscale entropy, fuzzy entropy and hierarchical entropy. Based on hierarchical decomposition method, we developed hierarchical multiscale entropy and hierarchical fuzzy entropy. Support vector machine (SVM) was used to distinguish the test set including 39 cases of normal and 36 cases of pathological voices. Results showed that three level hierarchical entropy，hierarchical multiscale entropy and hierarchical fuzzy entropy all achieved higher recognition rates and better stabilities using the proposed method. Pathological voice’s three level hierarchical fuzzy entropy feature got a better and more stable SVM recognition rate of 97.33% by extracting 2000 points. Compared with fuzzy entropy, the recognition rate was increased about 4.00%. The entropy method provide valuable preference for clinical analysis of short pathological voice time series contaminated by noise, which is benefit for clinical application of pathological voice analysis.

Key words： pathological voice fuzzy entropy hierarchical entropy support vector machine (SVM)
