This highlights the pressing need for robust audio deepfake detection (ADD) systems capable of effectively mitigating these threats. For reliable performance, ADD systems must generalize well to emerging and unknown deepfake techniques, remain robust to variations in speech attributes (e.g., speaker identity, channel, codec), and integrate seamlessly with other biometric tools. In this presentation, we introduce SAMO, a novel multicenter one-class learning training strategy tailored for ADD. SAMO addresses the distribution mismatches between training and evaluation data while accounting for speaker diversity. We will also discuss ongoing efforts to extend speech deepfake detection to singing voice deepfakes and further expand from audio-only (uni-modal) to audio-visual (multi-modal) detection to combat video deepfakes. Another initiative explores audio watermarking, a proactive technique that embeds generative algorithm identifiers into audio or the generative model itself, enabling authorized entities to trace the origins of deepfake speech. + - Bio: You (Neil) Zhang is a PhD candidate in the Audio Information Research (AIR) Lab at the University of Rochester, working with Prof. Zhiyao Duan.
