Abstract
An apparatus for selecting a cohort model for use in a speaker verification system includes a model generator ( ) for determining a target speaker model ( ) from a speech sample collected from the target speaker ( ). A cohort selector ( ) determines a similarity value between each of a number of predetermined existing speaker models from a model pool ( ) and the target speaker model ( ) and a dissimilarity value between each of the existing speaker models and any previously selected cohort models ( ). An existing speaker model which is most similar to the target speaker model, but most dissimilar to previously chosen cohort models, is then chosen as another cohort model for the target speaker.
