A QUERY BY HUMMING SYSTEM USING PLURAL MATCHING ALGORITHM BASED ON SVM

摘要

PURPOSE: A sound source search system and a method combining matching algorithms based on a plurality of SVM searching humming are provided to combine DTW(Dynamic Time Warping), EMD(Earth Mover's Distance) and matching score obtained from LS(Linear Scaling) method thereby providing exact sound source search result. CONSTITUTION: An audio signal analyzer(120) analyzes audio signal and extracts feature value of the audio signal. An audio signal matching searcher(140) uses feature value of corrected audio signal and applies the first and the second matching algorithm and produces the first and the second output value. The audio signal matching searcher uses the first and the second output value as an input and produces similarity measured value and searches and extracts sound source having high similarity based on the produced similarity measured value from sound source data base.
