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.关键词
