Background Specificity in Forensic Voice Comparison and Its Relation to the Bayesian Prior Probability

Wagner, Michael; Kinoshita, Yuko

Description

This study investigates the effect of background data specifici-ty on likelihood ratio and prior odds, and consequently on the posterior odds outcome. It is motivated by discussions on the correct choice of speaker recognition background, particularly in forensic voice comparison. We performed strictly controlled experiments with the ANDOSL database where background specificity is the sole independent variable. Results show that target and non-target scores are better separated with less...[Show more]
