# Synthetic voice detection

ElevenLabs added synthetic voice detection to ElevenAgents, which picks up traces in a live audio stream and can tell whether a caller is human or AI, so agencies can set queueing, routing and limits on sensitive actions. Governments facing a surge of requests filed by AI agents had previously relied on fees, IP blocks and stricter forms to add friction. On Czech employment and benefits hotlines, agents handle roughly 5,000 calls a day, independently resolve around 85% of calls, and raise answer rates from about 60% to near-universal coverage.
