How to Create Character Voices with ChatGPT
Character voice creation with ChatGPT and ToolRouter. Multiple voices from one recording.
Tool
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.

Example Prompt
Try this with ChatGPT using the Voice Transformer tool
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
