Multi-Prototype Variational Information Bottleneck for SSL-Based Speech Spoofing Detection

Rapid advances in text-to-speech (TTS) and voice conversion (VC) have substantially lowered the barrier to generating zero-shot spoofed speech, posing critical challenges for identity authentication, media forensics, and speech security. Current audio deepfake detection methods typically employ large-scale self-supervi...
