New audio watermarking method enhances robustness against reconstruction

Researchers have developed a new method for embedding imperceptible watermarks into audio that are robust against speech reconstruction models. This feature-aligned approach integrates watermarks with the original speech's feature distribution, enabling higher watermark energy for improved robustness without sacrificing perceptual quality. Experiments demonstrate that this technique maintains imperceptibility comparable to existing methods while significantly enhancing robustness against various speech reconstruction models. AI
