Deepfake voice attacks emerge as a severe threat by artificially impersonating human speech for malicious purposes. Existing defenses often rely on injecting noise to disrupt voice encoders, degrading audio quality and requiring prior knowledge of the voice generation model, which limits transferability. Additionally, traditional methods fail to provide fast protection in real-time applications like online meetings or instant messaging. To overcome the weaknesses, we propose ClearMask, a novel defense method against deepfake voice attacks. We display some speech samples to illustrate the effectiveness of ClearMask.
