# How to Create Voice Variations with Copilot

Copilot generates voice variations from within your IDE, ideal for developers building apps with voice personalization features. Create multiple voice options for your application, and Copilot can help you write the selection interface and audio playback code right alongside the voice generation workflow.

## Setup

{"mcpServers":{"toolrouter":{"command":"npx","args":["-y","toolrouter-mcp"]}}}

## Steps

1. Add ToolRouter to Copilot MCP config
2. In Copilot Chat: "Create 3 voice variations of this recording"
3. Copilot generates distinct variations
4. Ask: "Apply the winning variation to all remaining scripts"
5. Download and integrate into your project

## Example Prompt

```
Generate 3 voice variations of this app tutorial narration. Different styles for user preference testing.
```

## Tips

- Great for offering voice personalization options in apps and services
- Copilot can create the selection UI code alongside the voice variants
- Batch-apply the chosen variation to all content for consistency
