AI Voice Authentication

Voice authentication systems are increasingly bypassed by AI voice cloning tools that can replicate a target's voice from a few seconds of audio. GeraWitness adds a liveness and anti-spoofing layer to voice-authenticated transactions, escalating any authentication event that shows statistical signs of synthetic voice to a human agent for secondary verification before access is granted. GeraVoice and GeraClone both use GeraWitness as a mandatory anti-spoofing gate.
