Real-Time Audio Deepfake Tech Is Here

Real-time audio deepfakes have become a reality, enabling convincing voice impersonation with zero latency using open-source tools and consumer-grade hardware. NCC Group demonstrated a system that successfully fooled targets in voice phishing attacks by combining AI voice cloning with caller ID spoofing. The technology works on laptops with entry-level GPUs and requires only a button press to activate. While video deepfakes are advancing rapidly through models like Alibaba's WAN 2.2 and Google's Gemini Flash 2.5, they still lack real-time capability and show telltale signs like mismatched emotions. Security experts recommend developing alternative authentication methods beyond voice and video verification.
