AudioGemini 2.5 Flash TTS

Meet Pyra: voiceover

Gemini 2.5 Flash TTS. Pyra's own story, read in a warm storyteller voice: a voiceover you can drop straight into any video.

Reproduce

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'
