Abstract:

In most audio retrieval methods,retrieval target is usually treated as a whole unit,which results in slowing down the retrieval speed linearly due to target length. A novel audio retrieval algorithm based on segmentation is pre- sented in this paper. The retrieve target is divided into a series of segments,each of which can be searched and re- trieved independently. In the mean while,a retrieval window is used to decide which segments can be searched simul- taneously. This algorithm can achieve a very high retrieval speed that has no relationship with target length and the speed can be controlled by the size of retrieval window. Experimental results show that recall rate and accuracy rate are satisfied.
