1. A speaker segmentation method for associating an at least one segment of speech for each of at least two sides of a summed audio interaction, with one of the at least two sides of the interaction, using additional information, the method comprising:

  • a receiving step for receiving the summed audio interaction from a capturing and logging unit;

    a segmentation step for associating the at least one segment with one side of the summed audio interaction, the segmentation step comprisinga parameterization step for transforming a speech signal into a set of feature vectors and dividing the set into non-overlapping segments;

    an anchoring step for locating an anchor segment for each of the at least two sides of the summed audio interaction, the anchoring step comprising;

    selecting a homogenous segment as a first anchor segment;

    constructing a first model of the homogenous segment; and

    selecting a second anchor segment such that its model is different from the first model; and

    a modeling and classification step for associating at least one second segment with each side of the summed audio interaction; and

    a scoring step for assigning a score to said segmentation.
