Voice Arena
Voice Arena is a realtime healthcare voice-tool firewall that demonstrates how voice agents with tool access can leak sensitive patient data when raw tool responses reach the model.
Core trick
Runtime firewall intercepts tool responses and strips protected health information before results reach the voice model's context.
Description
Voice Arena is a realtime healthcare voice-tool firewall that demonstrates how voice agents with tool access can leak sensitive patient data when raw tool responses reach the model. It solves the gap left by prompt-only guardrails, which still expose secrets to the model and ask it not to repeat them, by enforcing a strict runtime data boundary so that unauthorized protected healthcare information (PHI) never enters the model’s response context.
