Techniques for a priori decision threshold estimation in speaker verification

A key problem for field applications in speaker verification is the issue of a priori threshold setting. In the context of the CAVE project several methods for estimating speakerindependent and speaker-dependent decision thresholds were compared. Relevant parameters are estimated from development data only, i.e. without resorting to additional client data. The various approaches were tested on the Dutch SESP database.
