Key point

Proposes a hierarchical safety framework to ensure responsible behavior and guardrail compliance for AI voice agents.

Details

A hierarchical safety framework is applied to ensure responsible behavior, user awareness, and guardrail compliance throughout the entire lifecycle of an AI voice agent. This framework includes pre-production safeguards, in-conversation enforcement mechanisms, and continuous monitoring.

The core components are as follows:

  • User Disclosure: Prompts users to immediately recognize that they are conversing with an AI at the start of the conversation.
  • System Prompt Guardrails: Defines the agent's scope of behavior by setting content safety, knowledge scope limits, identity constraints, privacy protection, and escalation boundaries.
  • Prompt Extraction Prevention: Instructs the agent to ignore user attempts to extract its instructions or role, and to stay focused on its original task.
  • Dead Switch: If attempts to violate guardrails are repeated, the agent is directed to safely end the conversation or transfer to a human agent.

Finally, the agent's safety is verified through evaluation criteria utilizing the LLM-as-a-judge approach.
