# How to Create Voice Variations with Claude

Claude turns voice variation generation into a collaborative exploration in your terminal. Describe the range of vocal styles you need -- warm, authoritative, energetic, calm -- and Claude generates distinct variations while explaining the acoustic differences between each. Ask follow-up questions to refine specific variations or request additional styles in the same session.

3. Claude generates distinct variations with different vocal characteristics
4. Compare the variations and select your favorites
5. Download the versions you want to use

## Example Prompt
