摘要
随着多媒体和Internet技术的广泛应用和深入普及,多媒体数据的数量正在飞速增长,音频数据作为多媒体数据的重要组成部分,其信息量也在不断膨胀。如何有效的对音频信息进行检索成为现代信息检索的一个重要的研究领域。然而,音频数据同传统的文本数据不同,文本检索中的相关技术不能简单地应用到音频信息检索中,因为后者往往是基于语义的,所以不可避免地要用到音频数据的特征提取和模式匹配等技术。本文将对音频数据检索相关技术和系统做一综述性的介绍。
With the rapid development and widely deployment of multimedia and Internet Technology, there has been a tremendous increase in the amount of multimedia data. This has caused the information contained in audio, which is an important part of multimedia data, to greatly expand. Audio information retrieval hence becomes a significant research field of modern information retrieval. Unlike text retrieval, however, audio information retrieval is usually semantic oriented and such technologies as feature extraction and pattern matching will be necessarily used. This article presents an overview on these technologies as well as some audio retrieval systems.
