Thanks — great question. You're asking if ElevenLabs Agents can integrate with LiveKit; yes — LiveKit supports ElevenLabs for both Text-to-Speech (TTS) and Speech-to-Text (STT), so you can build voice agents that transcribe user audio and synthesize responses. Quick summary of what you can do and how: • TTS: Use ElevenLabs voices (for example: Alice, Chris, Eric, Jessica) and models like

eleven_multilingual_v2

. You can use ElevenLabs through: ◦ LiveKit Inference (LiveKit handles integration/billing), or ◦ The ElevenLabs plugin available for Python and Node.js (

livekit-agents[elevenlabs]

) so you can use your own ElevenLabs API key. • STT: Real-time transcription is supported (e.g.,

scribe_v2_realtime

) with automatic language detection for many languages. This is available via LiveKit Inference or the ElevenLabs STT plugin. • How it fits in an agent: Typical setup uses an

AgentSession

with an STT component (to transcribe user speech) and a TTS component (to generate spoken responses). Example (Python):

session = AgentSession(
    stt=elevenlabs.STT(model="scribe_v2_realtime"),
    tts=elevenlabs.TTS(voice_id="YOUR_VOICE_ID", model="eleven_multilingual_v2")
)

• Authentication: You’ll need an ElevenLabs API key (set as

ELEVEN_API_KEY

when using the plugin). • Deployment / Pricing notes: On LiveKit Cloud, active agent sessions are billed (agent session minutes). LiveKit Cloud also provides observability (session analytics, logs, latency) and supports deployment features like warm agents and graceful draining. If you'd like, I can: • Walk you through a minimal Node or Python example to get an agent running with ElevenLabs TTS/STT. • Help you pick the right ElevenLabs model/voice for your use case. • Explain differences between using LiveKit Inference vs. the plugin (for example, whether you want LiveKit to handle billing/integration or prefer to use your own ElevenLabs account). Which would you like next — a short Node sample, Python sample, or help choosing models/voices?
