The effect of correlation on strength of evidence estimates in Forensic Voice Comparison: Uni-and multivariate Likelihood Ratio-based discrimination with Australian English vowel acoustics

Rose, Philip

Description

The consequences of ignoring correlations between features in traditional forensic speaker recognition are investigated. Two likelihood ratio-based discrimination experiments on the same multivariate formant data are described, one taking correlation into account and the other not doing so. The discrimination is performed using Naïve Bayes univariate, and multivariate generative Likelihood Ratios (LRs) as discriminant functions, exemplified with Tippett plots and evaluated with the Cllr cost...[Show more]
