A new paper, "The Watermark Shortcut," reveals a critical flaw in audio deepfake detection systems that rely on watermarking. When synthetic speech is watermarked and real speech is not, detectors incorrectly flag the watermark as an indicator of a fake voice. This leads to degraded performance, the ability for watermarked fakes to evade detection once unwatermarked, and the misclassification of real speech as fake. The researchers demonstrated this issue in both white-box and black-box experiments, including with a commercial API, and have released a dataset called WASP to aid further research. AI
