First Claim
Patent Images
1. A method for blind change detection of audio segments comprising:
- providing an input audio stream to be segmented;
applying at least two change detection audio segmentation processes to said input audio stream and obtaining candidate change points from each;
combining said candidate change points of each said applied processes for audio segmentation change detection; and
, removing invalid candidate change points to thereby optimize audio segmentation change points of the audio stream.

Abstract
A system, method and computer program product for performing blind change detection audio segmentation that combines hypothesized boundaries from several segmentation algorithms to achieve the final segmentation of the audio stream. Automatic segmentation of the audio streams according to the system and method of the invention may be used for many applications like speech recognition, speaker recognition, audio data mining, online audio indexing, and information retrieval systems, where the actual boundaries of the audio segments are required.
