Voice conversion transforms a live speaker’s voice in real time so that it sounds like a different person, while preserving the speaker’s words and timing. The attacker speaks normally; the system translates the audio output into the target’s voice on the fly.

• A model trained on the target voice converts incoming speech features in real time
• Latency is low enough to support natural conversation over phone or VoIP
• The attacker retains full control over what is said because they’re driving the conversation directly

• Live video calls where the attacker speaks as the executive in real time
• Real-time impersonation against contact center agents during transaction approvals
• Live verification calls where the attacker improvises responses in the target’s voice
• Cross-border fraud where the attacker masks their actual accent
• Fake interviews where the candidate’s voice is converted on the fly
