WaveScat introduces a new family of feature extractors for speech deepfake detection that merges wavelet scattering transform (WST) with self‑supervised learning. By cascading wavelet convolutions with modulus nonlinearities, WaveScat produces deformation‑stable, multi‑scale features that capture both low‑level spectral details and higher‑level information. Experiments on Deepfake‑Eval‑2024 and cross‑dataset tests (SpoofCeleb, In‑the‑Wild, ASVspoof 5) demonstrate that WaveScat significantly outperforms existing front‑ends, with a small averaging scale and high‑frequency directional resolution proving crucial for detecting subtle artifacts.

The rapid advancement of synthetic speech generation methods has made audio deepfake detection a critical challenge in multimedia forensics. While recent approaches achieve high detection accuracy, they typically rely on black-box architectures that offer limited interpretability and high computational complexity.
The paper introduces WST-Graph, a topology-preserving wavelet scattering front-end designed for speech deepfake detection. It reconstructs wavelet scattering paths into a sparse modulation‑carrier grid that feeds an AASIST graph backend, employing modulation‑level normalization and adaptive local attention pooling to produce fixed relative‑time representations while keeping acoustic axes intact. The resulting waveform‑to‑graph interface uses about 60% fewer trainable parameters than AASIST yet remains competitive, showing clear improvements on selected out‑of‑domain benchmarks.
AudioFuse is a hybrid architecture that jointly learns from spectrograms and raw waveforms to classify phonocardiograms. It combines a wide-and-shallow Vision Transformer for spectral features with a shallow 1D CNN for temporal waveforms, reducing overfitting while capturing complementary information. On the PhysioNet 2016 dataset, AudioFuse achieves a state‑of‑the‑art ROC‑AUC of 0.8608 and shows superior robustness to domain shift on the PASCAL dataset, outperforming both spectrogram‑only and waveform‑only baselines.
