# How to Create Voice Variations with OpenClaw

OpenClaw automates voice variation generation as a structured batch operation, producing dozens of distinct vocal styles from a single source recording in one run. Each variation comes with labeled metadata -- vocal characteristics, pitch range, energy level -- ready for direct import into A/B testing frameworks or content management systems.

## Setup

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

## Steps

1. Connect ToolRouter: openclaw mcp add toolrouter -- npx -y toolrouter-mcp
2. Ask OpenClaw: "Create voice variations of this recording"
3. OpenClaw generates several distinct versions
4. Compare and select the best variations
5. Download for your project or testing

## Example Prompt

```
Generate 4 voice variations of this announcement. I need different styles to test with our audience.
```

## Tips

- Ask for variations that differ meaningfully, not just subtly
- Use variations for audience testing before committing to a voice for a campaign
- Generate variations early in the production process to inform creative direction
