Adversarial Multi-Task Learning for Speaker Normalization in Replay Detection

ICASSP 2020accepted

Spoofing detection algorithms in voice biometrics are adversely affected by differences in the speech characteristics of the various target users. In this paper, we propose a novel speaker normalisation technique that employs adversarial multi-task learning to compensate for this speaker variability…
