Lightweight Model Attribution and Detection of Synthetic Speech via Audio Residual Fingerprints

arXiv — cs.LGFriday, December 12, 2025 at 5:00:00 AM
  • A new lightweight, training-free method has been developed for detecting synthetic speech and attributing it to its source model, addressing the growing concerns of impersonation and misinformation as speech generation technologies advance. The approach involves computing standardized average residuals to extract model-agnostic fingerprints that capture synthesis artifacts, achieving AUROC scores above 99% across various synthesis systems and languages.
  • This development is significant as it enhances digital forensics and security applications by providing a reliable means to differentiate between real and synthetic speech, thereby mitigating risks associated with the misuse of advanced speech generation technologies. The method's robustness against audio distortions further underscores its practical utility in real-world scenarios.
  • The emergence of this detection technique aligns with ongoing efforts in the field of artificial intelligence to address challenges posed by deepfakes and synthetic media, highlighting a broader trend towards developing frameworks that ensure the integrity of audio and visual content. As various models for speech and audio generation continue to evolve, the need for effective detection mechanisms becomes increasingly critical in maintaining trust and security in digital communications.
