Write for the ear
Long, formal sentences can make synthetic narration sound mechanical. Read the script aloud and rewrite passages that do not sound natural when spoken.
Create room to breathe
Punctuation and short breaks help signal where a narrator should pause. Listen for uninterrupted runs of speech and give important phrases enough space.
Test delivery in context
Pitch variation, emphasis and model settings affect how a voice feels. Compare a short passage using different delivery choices before producing the full narration. Keep a consistent voice across uploads, while adjusting delivery to the subject.
