Tutorials

Build your first voice agent

From empty project to a browser-ready voice agent in under 30 minutes.

  1. Create an Agent in the ElevenLabs dashboard and pick a voice.
  2. Write a focused system prompt — one job, one persona, one escalation path.
  3. Add 3–5 tools (e.g. lookup order, book meeting, escalate).
  4. Upload your knowledge base and test with the built-in simulator.
  5. Drop the React SDK snippet into your app and ship behind a feature flag.

Put an agent on a phone number

Wire ElevenAgents to Twilio so the same agent handles inbound calls.

  1. Provision a Twilio number and enable Programmable Voice.
  2. Point the webhook at ElevenLabs' Twilio integration URL.
  3. Set a fallback human transfer number in the agent config.
  4. Test with a real call, then enable call recording + transcript export.
  5. Monitor evals for the first 100 calls before removing the safety net.
FAQs
What latency should I expect?+

First audio in ~400–700ms on WebRTC in most regions — competitive with the fastest voice-agent platforms available.

Can agents transfer to a human?+

Yes, via tool calls that trigger a warm handoff over Twilio or your existing telephony.

Is ElevenAgents production-ready?+

For most support, sales-qualification and product use cases — yes. High-stakes regulated flows still deserve a human-in-the-loop.
