R-Norm: Improving Inter-Speaker Variability Modelling at the Score Level via Regression Score Normalisation

Vandyke, David; Wagner, Michael; Goecke, Roland

Description

This paper presents a new method of score post-processing which utilises previously hidden relationships among client models and test probes that are found within the scores produced by an automatic speaker recognition system. We suggest the name r-Norm (for Regression Normalisation) for the method, which can be viewed as both a score normalisation process and as a novel and improved modelling technique of inter-speaker variability. The key component of the method lies in learning a regression...[Show more]
