session = AgentSession(
    tts="elevenlabs/eleven_turbo_v2_5:alice",
    # ... llm, stt, vad, turn_detection, etc.
)

import { AgentSession } from '@livekit/agents';

session = new AgentSession({
    tts: "elevenlabs/eleven_turbo_v2_5:alice",
    // ... tts, stt, vad, turn_detection, etc.
});

Parameters

To customize additional parameters, use the TTS class from the inference module:

from livekit.agents import AgentSession, inference

session = AgentSession(
    tts=inference.TTS(
        model="elevenlabs/eleven_turbo_v2_5", 
        voice="alice", 
        language="en"
    ),
    # ... tts, stt, vad, turn_detection, etc.

Custom & community voices unavailable

Custom and community ElevenLabs voices, including voice cloning, are not yet supported in LiveKit Inference. To use these voices, create your own ElevenLabs account and use the ElevenLabs plugin for LiveKit Agents instead.
