Research questionHow can watermarks in generated speech remain detectable after neural audio transformations?Watermarks embedded in speech can become unreliable after neural codecs, denoising, vocoding, and other processing used in storage or transmission. This undermines efforts to verify audio provenance while preserving an imperceptible listening experience.

Latest papersRecent research connected to this question, newest first.CRAW: Codec Robust Audio WatermarkingThe source concerns post-hoc watermarking of generated speech and reports experiments involving neural codecs, denoisers, and vocoders. It presents evidence about robustness and perceptual quality, but does not establish performance across unspecified processing conditions or deployment environments.research paper · Sep 2, 2026
