摘要
介绍了基于内容的音频检索系统的基本结构,并在研究国内外相关文献的基础上,分析了音频检索算法的主要特点,划分为以下几种类型:近似字符串匹配算法、基于树结构的音频检索算法、基于动态时间规整的音频检索算法、基于隐马尔克夫模型的音频检索算法以及其它音频检索算法.
The basic structure of Content-based audio retrieval system is introduced, and the audio retrieval algorithms is summarized based on an in-depth analysis of domestic and foreign relevant literature. According to the main features of the algorithms, they are divided into the following several types： approximate string matching algorithm, tree-based algorithm, dynamic time warping algorithm, HMM-based algorithm, and other kind of the audio retrieval algorithms.
