How to use Audio Generator

A compact decision guide for placing this pipeline in a workflow.

Best for

  • Narration and voiceover in 70+ languages
  • Text-to-speech with natural language style control (e.g. 'speak warmly', 'whisper', 'excited tone')
  • Multi-voice content with dozens of expressive voices
  • Multilingual scripts, the language is auto-detected from the text

Tips

  • Write narration in short, clear sentences for better pacing
  • Use punctuation to control pauses: periods for full stops, commas for brief pauses, ellipsis for long pauses
  • Leave the voice on Auto and the AI picks one that matches the style instructions, or pin a specific voice if you want a recurring character
  • Use natural language style hints: 'speak slowly and dramatically', 'cheerful and upbeat', 'calm and reassuring'
