Compact SSL backbones crucial for audio deepfake detection, study finds

A new study published on arXiv investigates the effectiveness of compact self-supervised learning (SSL) backbones for audio deepfake detection. Researchers introduced RAPTOR, a Representation Aware Pairwise-gated Transformer, to evaluate compact HuBERT and WavLM models across 14 cross-domain benchmarks. The findings suggest that multilingual HuBERT pre-training is crucial for cross-domain robustness, allowing smaller models to perform comparably to larger commercial systems. The study also highlights that the SSL pre-training trajectory, rather than model scale, is the key factor for reliable audio deepfake detection. AI

IMPACT Findings suggest that smaller, well-pre-trained models can achieve high performance in audio deepfake detection, potentially reducing computational costs and increasing accessibility.

    Do Compact SSL Backbones Matter for Audio Deepfake Detection? A Controlled Study with RAPTOR

    arXiv:2603.06164v2 Announce Type: replace-cross Abstract: Self-supervised learning (SSL) underpins modern audio deepfake detection, yet most prior work centers on a single large wav2vec2-XLSR backbone, leaving compact under studied. We present RAPTOR, Representation Aware Pairwis…
