Joint Optimization of Speaker and Spoof Detectors for Spoofing-Robust Automatic Speaker Verification

Oğuzhan 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…

Optimizing a-DCF for Spoofing-Robust Speaker Verification

Oğuzhan 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…
