LambdaMark: Semantic Audio Watermarking for Robustness and Radioactivity

Researchers introduce LambdaMark, a novel audio watermarking technique that embeds multi-bit information into semantic audio representations to prevent unauthorized voice cloning and speaker impersonation. Unlike existing methods that operate on low-level signals, LambdaMark achieves both robustness against distortions and 'radioactivity'—the property of being learned and preserved by downstream finetuned models—making it significantly more resistant to removal attacks.

The Watermark Shortcut: How Provenance Marking Sabotages Audio Deepfake Detection

Researchers discovered that audio deepfake detectors trained on watermarked synthetic speech and unwatermarked real speech exploit watermarks as a spurious shortcut, causing three critical failures: poor generalization, watermarked fakes evading detection, and real watermarked speech being flagged as fake. The vulnerability affects commercial platforms like ElevenLabs and AudioSeal, though retraining detectors with watermarks on both classes resolves the issue.

Feature-Aligned Speech Watermarking for Robustness to Reconstruction Distortions

Researchers propose a feature-aligned speech watermarking method that embeds imperceptible identifiable information into audio while maintaining robustness against speech reconstruction models. By aligning watermarks with original speech feature distributions, the technique overcomes the traditional robustness-fidelity trade-off that has limited previous audio watermarking approaches.
