Tips for natural-sounding speech
- Use full sentences and punctuation — commas and full stops become pauses.
- Blank lines between paragraphs give a longer breath.
- Write numbers the way they should be read (“twenty twenty-six” vs “2026”) if a voice gets them wrong.
- For narration try Heart or Emma; for a calm male voice try Michael or George.
