Audio analysis system and method using audio segment characterisation

摘要

A method of matching an input audio signal to one or more audio segments within a plurality of audio segments, the method comprising: receiving the input audio signal; processing the input audio signal to determine structural parameter feature data related to the received input audio signal; analysing the determined structural parameter feature data to extract semantic feature data; comparing the feature data of the input audio signal to pre-processed feature data relating to the plurality of audio segments in order to match one or more audio segments within a similarity threshold of the input audio signal; outputting a search result on the basis of the matched one or more audio segments wherein semantic feature data is extracted from the structural parameter data using a supervised learning technique.
