# How to Replace Product Demo Voiceover with OpenClaw

OpenClaw automates voiceover replacement across your entire demo library in batch. Provide updated scripts and target languages, and it processes every video systematically, producing organized output with consistent voice quality across all demos. Structured logs track which demos have been updated and which still need new scripts.

## Setup

openclaw mcp add toolrouter -- npx -y toolrouter-mcp

## Steps

1. Connect ToolRouter: openclaw mcp add toolrouter -- npx -y toolrouter-mcp
2. Ask OpenClaw: "Replace the voiceover on this product demo"
3. OpenClaw generates the replacement narration using dub_audio
4. Review the output and request voice or pacing adjustments
5. Create multilingual versions for your global demo library

## Example Prompt

```
Replace the outdated voiceover on our product demo with this new script. Make it sound natural and professional.
```

## Tips

- Keep your original video files so you can re-dub whenever the product changes
- Ask for feedback on whether the pacing matches the screen transitions
- Generate multiple voice options to find the best fit for your brand
