Replicate mismatch between test/background and development databases: The impact on the performance of likelihood ratio-based forensic voice comparison
In this paper, we report on a study which demonstrates that the mismatch in within-speaker replicate numbers (the number of tokens used to model each sample) between test/background and development databases has a large impact on the performance of a forensic voice comparison (FVC) system. We describe how and to what extent the different degrees of the mismatch influence the performance of the FVC system. The performance of an FVC system based on temporal MFCC features and the Multivariate...[Show more]
