Abstract
C-BET is the Comprehensive Biometrics Evaluation Toolkit developed by CBSA in order to analyze the suitability of biometric systems for fully-automated border/access control applications. Following the multiorder score analysis and the threshold-validated analysis defined within the C-BET framework, the paper presents the results of the C-BET evaluation of a commercial voice biometric product. In addition to error tradeoff and ranking curves traditionally reported elsewhere, the paper presents the results on the newly introduced performance metrics: threshold-validated recognition ranking and non-confident decisions due to multiple threshold-validated scores. The results are obtained on over a million voice audio clip comparisons. Good biometric evaluation practices offered within C-BET framework are presented.
