Writing Scripts for AI Presenters That Sound Natural

Most robotic-sounding avatar videos are script problems, not technology problems. Writing for the ear instead of the eye fixes much of it.

Write to be spoken

Use short sentences, contractions and everyday words. Read each line aloud; if you stumble, the avatar's voice will too.

Avoid long lists in a single breath. Break them into separate lines or show them on screen.

Pacing and structure

Lead with the point.
One idea per scene.
Add pauses where a human would breathe.
Pair narration with visuals so the presenter is not the only thing on screen.

Most tools let you adjust pauses and emphasis; experiment in each platform.

Test before you finalize

Generate a short sample, watch it without the script in front of you, and mark anything that sounds off. Spell out acronyms or unusual names phonetically if the tool mispronounces them.

Key takeaways

Write for the ear.
One idea per scene.
Test a sample first.
