A Bayesian approach to the verification problem applications to speaker verification.

A Bayesian approach to the verification problem applications to speaker verification.

In this paper, we study the general verification problem from a Bayesian viewpoint. In the Bayesian approach, the verification decision is made by evaluating Bayes factors against a critical threshold. The calculation of the Bayes factors in turn requires the computation of several Bayesian predicti...
