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.

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 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.
摘要翻译：目的：提供一种基于多个SVM搜索蜂鸣的组合匹配算法的声源搜索系统和方法，组合使用间距进行DP（动态编程）匹配计算的3种匹配分数，使用前后间距值进行DP匹配， DP使用音调差与第一声音到SVR的匹配，从而提供精确的搜索结果。构成：音频信号匹配搜索器（140）应用校正音频信号的音调值，与校正音频信号相邻的音调值与校正音频信号的音高和第一音高和差值之间的动态匹配算法的差值的排列，以及产生第一，第二和第三输出值。音频信号匹配搜索单元使用第三输出值作为输入，并产生相似度测量值。
