How to Create Character Voices with Claude
Create character voices with Claude and ToolRouter. Transform one voice into many distinct characters.
Tool
Claude turns voice transformation into a conversational workflow right in your terminal. Describe the character you want -- personality, age, tone -- and Claude will ask clarifying questions about vocal texture and intensity before applying the transformation. Iterate naturally by saying things like "make it raspier" or "younger sounding" until each character is exactly right.

Steps
Once connected (see setup above), use the Voice Transformer tool:
- Ask Claude: "Transform this voice recording into a deep villain character using voice-transformer"
- Claude applies the transformation and returns the modified audio
- Request: "Now create a cheerful young character from the same recording"
- Download each character voice for your project
Example Prompt
Try this with Claude using the Voice Transformer tool
I have one voice recording of dialogue. Transform it into 3 distinct characters: a deep-voiced villain, a bright young hero, and a wise elderly mentor. Each should sound like a completely different person.
Tips
- Record clean, neutral dialogue as your source for the most transformation flexibility
- Ask Claude to create a character voice profile you can reuse across sessions
- Generate test lines for each character and iterate before processing all dialogue
