摘要
本文提出了一种采用音频流序列进行比对的技术,同时对运用该技术的音频切换器原理及比对方法进行了探讨,该方法从广播音频信号中提取有效的特征参数形成音频流序列,利用模式识别方式分析统计信号源之间的相似度,用来对多路广播音频信号的内容进行比对,以此判断音频信号源内容的准确性.
Abstract
In this paper,a technology of comparing audio stream sequences is proposed,and the principle and comparison method of audio switcher using this technology are discussed,which extracts effective feature parameters from broadcast audio signals to form audio stream sequences,and analyzes the similarity between statistical signal sources by using pattern recognition to compare the content of multi-channel broadcast audio signals,so as to judge the accuracy of audio signal source content.
