Plugin guides
Google Meet configuration
Plugin config defaults, optional overrides, and the ElevenLabs and Twilio config examples. Part of the Google Meet plugin guide.
Config
The common Chrome agent path only needs the plugin enabled, BlackHole, SoX, a realtime provider key, and a configured OpenClaw TTS provider:
{ plugins: { entries: { "google-meet": { enabled: true, config: {}, }, }, },}Defaults
| Key | Default | Notes |
|---|---|---|
defaultTransport |
"chrome" |
|
defaultMode |
"agent" |
"realtime" is accepted as a legacy alias for "agent"; new callers should say "agent" |
chromeNode.node |
unset | Node id/name/IP for chrome-node; required when more than one capable node may be connected |
chrome.launch |
true |
Launch Chrome for the join; set false only when reusing an already-open session |
chrome.audioBackend |
"auto" |
Selects blackhole-2ch on macOS or pipewire-pulse on Linux; set an explicit backend when a paired Chrome node uses a different OS than the Gateway |
chrome.guestName |
"OpenClaw Agent" |
Shown on the signed-out Meet guest screen |
chrome.autoJoin |
true |
Best-effort guest-name fill and Join Now click on chrome-node |
chrome.reuseExistingTab |
true |
Activates an existing Meet tab instead of opening duplicates |
chrome.waitForInCallMs |
20000 |
Wait for the Meet tab to report in-call before the talk-back intro fires |
chrome.audioFormat |
"pcm16-24khz" |
Command-pair audio format; "g711-ulaw-8khz" is only for legacy/custom command pairs that emit telephony audio |
chrome.audioBufferBytes |
4096 |
Processing buffer used to derive generated command latency; values are clamped to a minimum of 17 bytes |
chrome.audioInputCommand |
generated native command | SoX/CoreAudio on macOS; parec from the OpenClaw PipeWire-Pulse source on Linux |
chrome.audioOutputCommand |
generated native command | SoX/CoreAudio on macOS; pacat into the OpenClaw PipeWire-Pulse sink on Linux |
chrome.bargeInInputCommand |
unset | Optional local microphone command writing signed 16-bit little-endian mono PCM for human barge-in detection during assistant playback; applies to the Gateway-hosted command-pair bridge |
chrome.bargeInRmsThreshold |
650 |
RMS level counted as human interruption |
chrome.bargeInPeakThreshold |
2500 |
Peak level counted as human interruption |
chrome.bargeInCooldownMs |
900 |
Minimum delay between repeated interruption clears |
mode (per-request) |
"agent" |
Talk-back mode; see the Agent and bidi modes table |
realtime.provider |
"openai" |
Compatibility fallback used when the scoped fields below are unset |
realtime.transcriptionProvider |
"openai" |
Provider id used by agent mode for realtime transcription |
realtime.voiceProvider |
unset | Provider id used by bidi mode for direct realtime voice; set to "google" for Gemini Live while keeping agent-mode transcription on OpenAI. Pair with realtime.model to pick the specific Gemini Live model. |
realtime.toolPolicy |
"safe-read-only" |
See Agent and bidi modes |
realtime.instructions |
brief spoken-reply instructions | Tells the model to speak briefly and use openclaw_agent_consult for deeper answers |
realtime.introMessage |
"Say exactly: I'm here and listening." |
Spoken once when the realtime bridge connects; set to "" to join silently |
realtime.agentId |
"main" |
OpenClaw agent id used for openclaw_agent_consult |
voiceCall.enabled |
true |
Delegates the Twilio PSTN call, DTMF, and intro greeting to the Voice Call plugin |
voiceCall.dtmfDelayMs |
12000 |
Leading wait before playing a PIN-derived DTMF sequence over Twilio |
voiceCall.postDtmfSpeechDelayMs |
5000 |
Delay before requesting the realtime intro greeting after Voice Call starts the Twilio leg |
chrome.audioBridgeCommand and chrome.audioBridgeHealthCommand let an external bridge own the whole local audio path instead of chrome.audioInputCommand/chrome.audioOutputCommand; see Notes for the constraint on which mode can use them.
An openclaw doctor --fix migration exists for the legacy realtime.provider: "google" shape: it moves that intent to realtime.voiceProvider: "google" plus realtime.transcriptionProvider: "openai" when those fields are not already set.
Optional overrides
{ defaults: { meeting: "https://meet.google.com/abc-defg-hij", }, browser: { defaultProfile: "openclaw", }, chrome: { guestName: "OpenClaw Agent", waitForInCallMs: 30000, bargeInInputCommand: [ "sox", "-q", "-t", "coreaudio", "External Microphone", "-r", "24000", "-c", "1", "-b", "16", "-e", "signed-integer", "-t", "raw", "-", ], }, chromeNode: { node: "parallels-macos", }, defaultMode: "agent", realtime: { provider: "openai", transcriptionProvider: "openai", voiceProvider: "google", model: "gemini-3.1-flash-live-preview", agentId: "jay", toolPolicy: "owner", introMessage: "Say exactly: I'm here.", providers: { google: { speakerVoice: "Kore", }, }, },}ElevenLabs for both agent-mode listening and speaking:
{ tts: { provider: "elevenlabs", providers: { elevenlabs: { modelId: "eleven_v3", speakerVoiceId: "pMsXgVXv3BLzUgSXRplE", }, }, }, plugins: { entries: { "google-meet": { config: { realtime: { transcriptionProvider: "elevenlabs", providers: { elevenlabs: { modelId: "scribe_v2_realtime", audioFormat: "ulaw_8000", sampleRate: 8000, commitStrategy: "vad", }, }, }, }, }, }, },}The persistent Meet voice comes from tts.providers.elevenlabs.speakerVoiceId. Agent replies can also use per-reply [[tts:speakerVoiceId=... model=eleven_v3]] directives when TTS model overrides are enabled, but config is the deterministic default for meetings. On join, logs show transcriptionProvider=elevenlabs, and each spoken reply logs provider=elevenlabs model=eleven_v3 speakerVoiceId=<voiceId>.
Twilio-only config:
{ defaultTransport: "twilio", twilio: { defaultDialInNumber: "+15551234567", defaultPin: "123456", }, voiceCall: { gatewayUrl: "ws://127.0.0.1:18789", },}With voiceCall.enabled: true (the default) and Twilio transport, Voice Call places the DTMF sequence before opening the realtime media stream, then uses the saved intro text as the initial realtime greeting. If voice-call is not enabled, Google Meet can still validate and record the dial plan but cannot place the Twilio call.
Leave voiceCall.gatewayUrl unset to use the local trusted Gateway runtime, which preserves the
invoking agent for the full call. A configured Gateway URL remains an explicit WebSocket target and
cannot authenticate plugin provenance; non-default agent joins fail closed instead of silently
using another agent. Run Google Meet and Voice Call in the same Gateway process when per-agent
routing is required.
