Joint Optimization of Speaker and Spoof Detectors for Spoofing-Robust Automatic Speaker Verification
OÄuzhan Kurnaz, Jagabandhu Mishra, Tomi H. Kinnunen +1
Spoofing-robust speaker verification (SASV) combines the tasks of speaker and spoof detection to authenticate speakers under adversarial settings. Many SASV systems rely on fusion…
Joint Optimization of ASV and CM tasks: BTUEF Team's Submission for WildSpoof Challenge
Oguzhan Kurnaz, Jagabandhu Mishra, Tomi Kinnunen +1
Spoofing-aware speaker verification (SASV) jointly addresses automatic speaker verification and spoofing countermeasures to improve robustness against adversarial attacks. In this…
Investigating the Potential of Multi-Stage Score Fusion in Spoofing-Aware Speaker Verification
Oguzhan Kurnaz, Tomi Kinnunen, Cemal Hanilci
Despite improvements in automatic speaker verification (ASV), vulnerability against spoofing attacks remains a major concern. In this study, we investigate the integration of ASV a…
Optimizing a-DCF for Spoofing-Robust Speaker Verification
OÄuzhan Kurnaz, Jagabandhu Mishra, Tomi H. Kinnunen +1
Automatic speaker verification (ASV) systems are vulnerable to spoofing attacks. We propose a spoofing-robust ASV system optimized directly for the recently introduced architecture…
Spoofing-Robust Speaker Verification Using Parallel Embedding Fusion: BTU Speech Group's Approach for ASVspoof5 Challenge
OÄuzhan Kurnaz, Selim Can DemirtaÅ, Aykut Büker +2
This paper introduces the parallel network-based spoofing-aware speaker verification (SASV) system developed by BTU Speech Group for the ASVspoof5 Challenge. The SASV system integr…
