1. A method of determining an utterance score for identifying a speaker from a group of speakers based on a first set of feature vectors of an utterance from the speaker, comprising:

  • transforming the first set of feature vectors into a second set of feature vectors using transformations specific to a segmentation unit;

    computing likelihood scores of the second set of feature vectors using speaker models trained by a mixture discriminate analysis using a collection of first sets of feature vectors from all the speakers in the group; and

    combining the likelihood scores to determine an utterance score.
