# How to Create Voice Variations with ChatGPT

ChatGPT creates voice variations with detailed strategic context, suggesting which vocal styles tend to perform best for your specific content type and audience. It generates a variation catalog with descriptions of each voice personality, making it easy for marketing teams to select the right option for A/B testing or audience segmentation.

## Setup

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

## Steps

1. Configure ToolRouter in ChatGPT
2. Ask: "Generate multiple voice variations of this recording"
3. ChatGPT creates several distinct versions
4. Request: "Label each variation with its vocal characteristics"
5. Download the variations for testing or deployment

## Example Prompt

```
Create 5 voice variations of this product demo narration. I want to A/B test which voice style gets the best engagement.
```

## Tips

- ChatGPT can suggest which vocal styles tend to perform best for your content type
- Ask for distinct enough variations that A/B test results will be statistically meaningful
- Label variations clearly for tracking performance across tests
