Abstract

The paper describes the fusion of heterogeneous speaker recognition systems in the STBU submission for the NIST speaker recognition evaluation 2006.

Annotation

This paper describes and discusses the `STBU' speaker recognition system, which performed well in the NIST Speaker Recognition Evaluation 2006 (SRE). STBU is a consortium of 4 partners: Spescom DataVoice (South Africa), TNO (The Netherlands), BUT (Czech Republic) and University of Stellenbosch (South Africa). The STBU system was a combination of three main kinds of sub-systems: (1) GMM, with shorttime MFCC or PLP features, (2) GMM-SVM, using GMM mean supervectors as input to an SVM, and (3) MLLR-SVM, using MLLR speaker adaptation coefficients derived from an English LVCSR system. All sub-systems made use of supervector subspace channel compensation methodsóeither eigenchannel adaptation or nuisance attribute projection. We document the design and performance of all sub-systems, as well as their fusion and calibration via logistic regression. Finally, we also present a cross-site fusion that was done with several additional systems from other NIST SRE-2006 participants.
