Tips for better results
The model reads exactly what you write, so small changes to the script make a big difference.
- 1Use punctuation for pacing: commas for short pauses, periods for full stops, an ellipsis for a beat.
- 2Write numbers, dates and abbreviations the way they should be spoken, for example “twenty twenty-six”.
- 3Draft on Turbo, then render the final take on the standard model.
- 4Lower expressiveness for calm narration; keep it high for ads and dialogue.
- 5For cloning, upload 30 seconds to 3 minutes of one speaker with no music or background noise.
