How to install Voice Reply

- Search for
voice-replyand click Install. - The skill activates automatically when an incoming message matches its description.
Install from the command line

This pulls voice-reply from ClawHub and installs it into ~/.openclaw/skills/voice-reply/. Restart the OpenClaw gateway afterwards so the new skill is discovered.
How to use Voice Reply
Once installed, Voice Reply activates on its own: when an incoming message on WhatsApp, Telegram, Slack, Discord, Feishu or Line matches the skill's description, your OpenClaw agent loads it and runs the workflow. You can also trigger it explicitly by describing the task in chat. No extra configuration is required after install.
Putting audio in front of an audience
Voice Reply works with audio. Getting from there to something postable is a separate job: ViralMint — an open-source video pipeline — pairs audio with footage or generated visuals, burns synced captions, and exports a finished short.
It runs as an MCP server, so an OpenClaw agent can drive it from the same chat you already use: ask for a short, and the render comes back finished. See how to connect a video pipeline to your agent.
