1. A computer-implemented method for blind change detection of audio segments comprising:

  • receiving an input audio stream to be segmented;

    applying two or more change detection audio segmentation processes to said input audio stream and obtaining a set of candidate change points from each;

    combining said sets of candidate change points of each said applied processes for audio segmentation change detection;

    calculating values of measurements of each said two or more change detection audio segmentation processes at every candidate change point of the combined sets; and

    ,removing invalid candidate change points based on said calculated values to thereby optimize valid audio segmentation change points of the audio stream,wherein a programmed processor device performs said applying, combining, calculating and removing.
