The Effect of Target/Non-Target Age Difference on Speaker Recognition Performance

George Doddington


The very large set of trials in the SRE10 extended evaluation [1] provides opportunity to study the effect of various factors on speaker recognition performance. This paper addresses the issue of age difference between target and non-target speakers and shows that false alarm probability is reduced substantially as the age difference increases. False alarm probability is significantly reduced for age differences of as little as five years, with an order of magnitude reduction in PFA for age differences of forty years or more, depending on the system being measured and the test condition.
