METHOD AND SYSTEM FOR AUDIO MATCHING

摘要

A method for audio matching is disclosed. The method is used for detecting audio sub segments matching with the audio samples in a standard audio database from an audio stream segment to be detected. The method comprises steps: generating energy envelope unit figures respectively for the audio stream segment to be detected and the audio samples in the standard audio database; selecting a candidate matching sub segment in the audio stream segment to be detected, and the candidate matching sub segment having the same length as the audio sample to be compared; comparing the segment points and the probability of the segment points of the energy envelope unit in the candidate matching sub segment with the segment points and the probability of the segment points of the audio sample to be compared and obtaining a matching point and matching probability of the matching point; computing similarity value between the candidate matching sub segment and the audio sample to be compared with comparability measuring function according to the matching probability of the matching point; judging whether the candidate matching sub segment and the audio sample to be compared are matching according to the similarity value.
