Researchers have developed a new framework called Speaker-Disentangled Metric Learning (SDML) to improve the accuracy of deepfake speech source verification. This framework addresses the challenge that current systems often assume source embeddings are independent of speaker traits, an assumption that may not hold true. SDML incorporates novel loss functions utilizing Chebyshev polynomial to stabilize optimization and Riemannian metric distances in hyperbolic space to reduce speaker information and enhance source feature discriminability. Experiments on the MLAAD benchmark demonstrated the framework's effectiveness, particularly under specialized protocols designed for source-speaker disentanglement. AI
IMPACT This research could lead to more robust detection of synthetic speech, improving security and trust in audio communications.
