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.
