# How to Create Character Voices with ChatGPT

ChatGPT makes character voice creation as simple as describing the character you want in plain language. Ask for a "grizzled pirate captain" or a "cheerful robot sidekick" and ChatGPT translates your creative vision into precise voice transformation parameters. It can also generate a full character voice guide with descriptions of each voice for your production team.

## Setup

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

## Steps

1. Configure ToolRouter in ChatGPT
2. Ask: "Transform this voice recording into different characters" and provide the audio
3. ChatGPT creates each character transformation
4. Request: "Make the villain deeper and add more rasp"
5. Download all character voice files

## Example Prompt

```
Transform this dialogue recording into 4 game NPC voices: tavern keeper (gruff), merchant (smooth), guard (commanding), and child (light). Each distinct.
```

## Tips

- ChatGPT can suggest character voice profiles based on your character descriptions
- Ask for subtle differences for characters of similar type -- each guard should sound unique
- Generate a character voice gallery to review before committing to full dialogue processing
