Researchers have developed a new method to understand how deepfake speech detectors make their decisions. By using Integrated Gradients on self-supervised representations, they can pinpoint specific moments in audio where the detector finds evidence of manipulation. This analysis revealed that different detectors focus on distinct audio artifacts, such as environmental noise, phoneme irregularities, or word boundary inconsistencies, which was then confirmed by causally masking these identified cues.
