ElevenLabs Releases Synthetic Voice Detection in ElevenAgents and Joins Personal Agent Protocol

ElevenLabs has introduced synthetic voice detection within its ElevenAgents platform to address the growing number of calls from personal AI agents. The feature analyzes the caller's speech in the first few seconds to determine if the caller is human or AI-generated, allowing businesses to configure specific routing rules. These rules can prioritize verified human customers, provide bounded interactions for AI agents, or block synthetic voices attempting sensitive actions like password resets. The detection runs on the live audio stream and does not rely solely on watermarks, enabling it to identify synthetic voices from various sources. Additionally, ElevenLabs is joining the Personal Agent Protocol working group, led by Meta and Sierra, as a design partner to help define standards for agent identification and authorization. The feature is currently available to enterprise customers supported by the Forward Deployed Engineering team and will expand to a broader group later this month.
