| 摘 要： | 大多数环境声是不和谐的,比语声和乐声更加不平稳。针对传统时频分析的不足,提出一种基于听觉感知的环境声特征提取方法。针对研究的小样本问题,采用支持向量机(Support Vector Machine,SVM)作为分类算法,对环境声进行分类。仿真结果表明所用特征及方法是有效的。

| Abstract: | Most of environmental sounds are not harmonious. Compared with speech and music sounds, environmental sounds are less stable. For the deficiencies of traditional time-frequency analysis, a method is proposed to extract environmental sound features based on auditory perception. In view of the problem of small sample, SVM is used as the classification algorithm to classify the environmental sounds. The simulation results show that the features and the method are effective. |
