clack

Deploy and manage Clack, a voice relay server for OpenClaw. Bridges voice input (WebSocket) through STT → OpenClaw agent → TTS, enabling real-time voice conversations with your agent. Supports ElevenLabs, OpenAI, and Deepgram for STT/TTS. Per-session provider selection — users can independently choose STT and TTS providers (including on-device) from the app settings. Encrypted connections via Domain (SSL) or Tailscale. Supports local speech mode where STT/TTS run on-device and only LLM calls go through the server. Use when a user wants to set up voice chat, voice relay, voice interface, Clack, or talk to their agent by voice.
