Abstract: 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.

Abstract: PURPOSE: A sound source search system and a method combining matching algorithms based on a plurality of SVM searching humming are provided to combine 3 kinds matching scores calculated from DP(Dynamic Programming) matching using pitch, DP matching using pitch value between front and rear and DP matching using pitch difference with first sound to SVR thereby providing exact search result. CONSTITUTION: An audio signal matching searcher(140) applies pitch values of corrected audio signal, arrangement of difference value between pitch value adjacent to the corrected audio signal and pitches of the corrected audio signal and dynamic matching algorithm in the first pitch and difference values and produces the first, the second and the third output values. The audio signal matching search unit uses the fist-third output value as input and produces similarity measured value.
