ElevenLabs

OpenClaw uses ElevenLabs for text-to-speech, batch speech-to-text with Scribe v2, and streaming STT with Scribe v2 Realtime.

Authentication

Set ELEVENLABS_API_KEY in the environment. XI_API_KEY is also accepted for compatibility with existing ElevenLabs tooling.

export ELEVENLABS_API_KEY="..."

Text-to-speech

{  messages: {    tts: {      providers: {        elevenlabs: {          apiKey: "${ELEVENLABS_API_KEY}",          speakerVoiceId: "pMsXgVXv3BLzUgSXRplE",          modelId: "eleven_multilingual_v2",        },      },    },  },}

Set modelId to eleven_v3 to use ElevenLabs v3 TTS. OpenClaw keeps eleven_multilingual_v2 as the default for existing installs.

Discord voice channels use ElevenLabs' streaming TTS endpoint when ElevenLabs is the selected voice.tts/messages.tts provider. Playback starts from the returned audio stream instead of waiting for OpenClaw to download and write the whole audio file first. latencyTier maps to ElevenLabs' optimize_streaming_latency query parameter for models that accept it; OpenClaw omits that parameter for eleven_v3, which rejects it.

Speech-to-text

Use Scribe v2 for inbound audio attachments and short recorded voice segments:

{  tools: {    media: {      audio: {        enabled: true,        models: [{ provider: "elevenlabs", model: "scribe_v2" }],      },    },  },}

OpenClaw sends multipart audio to ElevenLabs /v1/speech-to-text with model_id: "scribe_v2". Language hints map to language_code when present.

Streaming STT

The bundled elevenlabs plugin registers Scribe v2 Realtime for Voice Call and Google Meet agent-mode streaming transcription.

{  plugins: {    entries: {      "voice-call": {        config: {          streaming: {            enabled: true,            provider: "elevenlabs",            providers: {              elevenlabs: {                apiKey: "${ELEVENLABS_API_KEY}",                audioFormat: "ulaw_8000",                commitStrategy: "vad",                languageCode: "en",              },            },          },        },      },    },  },}

For Google Meet agent mode, set plugins.entries.google-meet.config.realtime.transcriptionProvider to "elevenlabs" and configure the same provider block under plugins.entries.google-meet.config.realtime.providers.elevenlabs.
