ElevenLabs · MIT
When
Real-time voice on a custom agent runtime via ElevenLabs Speech Engine (WebSocket, WebRTC, conversation tokens). They handle mic/STT/turn-taking/TTS; your server owns agent logic. Needs API key. Not LiveKit Agents OSS. Not the TTS-only skill.
The Catch
Your runtime, their STT/TTS. Cloud + API key, not LiveKit OSS. Free has no commercial license. Distinct from elevenlabs-text-to-speech.
