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.
