# How to Modify Voice Pitch with ChatGPT

ChatGPT translates your natural language pitch requests into technically precise adjustments. Describe the vocal quality you are targeting and ChatGPT recommends specific pitch shift amounts, explains the trade-offs of different adjustment levels, and generates a comparison report showing how the modified voice differs from the original across key acoustic dimensions.

## Setup

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

## Steps

1. Configure ToolRouter in ChatGPT
2. Ask: "Adjust the pitch of this voice recording" and specify direction and amount
3. ChatGPT processes the pitch modification
4. Request: "Fine-tune it -- a little higher" or "Perfect, now process the rest"
5. Download the adjusted audio

## Example Prompt

```
Raise the pitch of this recording slightly to make the speaker sound younger and more energetic. Keep it sounding natural.
```

## Tips

- ChatGPT can suggest optimal pitch adjustments based on your use case
- Ask for comparison samples at different pitch levels
- Subtle adjustments are often more effective than dramatic shifts
