Spooftral: Can Voxtral Audio-Language Model Detect Speech Spoofing?
Avishai Weizman, Yehuda Ben-Shimol, Itshak Lapidot
Self-supervised learning (SSL) countermeasures (CMs) have shown strong performance in recent years. However, they often show degraded performance while facing unseen spoofing attac…
Doubly Stochastic Mean-Shift Clustering
Tom Trigano, Yann Sepulcre, Itshak Lapidot
Standard Mean-Shift algorithms are notoriously sensitive to the bandwidth hyperparameter, particularly in data-scarce regimes where fixed-scale density estimation leads to fragment…
ELEAT-SAGA: Early & Late Integration with Evading Alternating Training for Spoof-Robust Speaker Verification
Amro Asali, Yehuda Ben-Shimol, Itshak Lapidot
Spoofing-robust automatic speaker verification (SASV) seeks to build automatic speaker verification systems that are robust against both zero-effort impostor attacks and sophistica…
