How to Use OpenClaw Talk Mode

OpenClaw Talk mode turns the assistant into a continuous voice loop: listen, transcribe, send to the main session, wait for the reply, and speak the answer through the active Talk provider. On macOS the docs describe an always-on overlay with Listening, Thinking, and Speaking phases. Replies are also written to WebChat, so voice conversations remain visible in the same gateway-backed session history instead of disappearing into audio-only state.

Enable the right capture flow

Talk mode is different from a one-off voice note. A short silence window sends the current transcript automatically. The documented default pause window is platform-specific when silenceTimeoutMs is unset: 700 ms on macOS and Android, 900 ms on iOS. Android exposes Talk in the Voice tab and keeps it running until toggled off or the node disconnects. Manual Mic and Talk are mutually exclusive capture modes, so choose the mode that matches the interaction you want.

Configure provider and voice behavior

The main config lives under talk in ~/.openclaw/openclaw.json. The docs show provider, provider-specific blocks, speechLocale, silenceTimeoutMs, and interruptOnSpeech. ElevenLabs can use voiceId, modelId, outputFormat, and an API key, falling back to environment variables where documented. MLX can use a local model id. System playback is available as a local provider path. Keep provider changes small and verify one voice path before layering fallbacks.

Use voice directives sparingly

The assistant can prefix a reply with a single JSON line to change voice settings for playback. The first non-empty line can include keys such as voice, model, speed, stability, similarity, lang, output_format, and once. Unknown keys are ignored, and once: true applies only to the current reply. That is useful for demos or role shifts, but do not let every response mutate voice defaults unless that is intentional.

Test interruption and permissions

Talk needs microphone and speech permissions. Test the full loop before trusting it in an always-on workspace: speak, pause, confirm the transcript appears, wait for the answer, then interrupt while it is speaking. On macOS, clicking the cloud stops speaking and clicking X exits Talk mode. The default interrupt behavior is one of Talk's best features because it keeps a spoken assistant from feeling like a voicemail you must wait through.

Make it operational

For production-like use, document the chosen provider, voice id, locale, silence timeout, and failure fallback. If Talk feels too eager, adjust silence. If it talks over people, verify interruption. If replies are not visible, check WebChat/session history. The OpenClaw Playbook helps turn Talk from a novelty into a usable operator interface: permissions known, provider known, transcript visible, and one recovery step written down.

Make voice usable in real rooms

The difference between a demo and a usable Talk setup is environmental testing. Try it in the actual room, with the actual microphone, at the volume people will use. Check whether the silence window cuts people off, whether interruption triggers on background noise, and whether the chosen voice feels too slow for operational replies. If you use a paid TTS provider, also write down the fallback if quota or auth fails. Voice interfaces fail socially before they fail technically: if the assistant talks too long, ignores interruptions, or responds from the wrong session, people stop trusting it. Tune for short, recoverable turns first.

Final verification

Before calling How to Use OpenClaw Talk Mode finished, perform one direct test, one failure test, and one rollback check. The direct test proves the happy path works. The failure test proves the documented guardrail is real, not just assumed. The rollback check tells the next operator how to undo the change without improvising. Save those notes beside the channel, node, or gateway config you changed. OpenClaw gets powerful when agents can act, but it stays trustworthy when every new surface has a small, repeatable verification habit attached to it.
