Dual-Branch Gated Fusion for Open-Set Audio Deepfake Source Tracing
Researchers have developed a new dual-branch gated fusion framework to improve the tracing of audio deepfake sources. This system combines XLSR-53 with a novel 66-dimensional descriptor called CORES, which captures a wider range of synthesis artifacts than previous methods. An input-conditioned gate adaptively weights these two branches to overcome representational imbalance and enhance performance on out-of-domain datasets. AI
IMPACT This research could lead to more robust detection of audio deepfakes, enhancing security and trust in digital communications.
