How to use an AI voice for narration.
5 min read · Updated October 30, 2026
A good AI voice turns a script into narration in minutes. The difference between robotic and natural comes mostly from how you write for it, and a few settings.

- Short sentences. If you run out of breath reading it aloud, shorten it.
- Say numbers and names the way you would speak them.
- Use commas and full stops where you want pauses.
- Read your script aloud once before generating.
Choosing a voice
Listen to several on the same paragraph. Warm voices suit explainers, firm voices suit stories with tension, and brighter voices suit upbeat content. Zlayo offers 15+ voices with notes on accent and tone, and speed, volume and pitch controls.
Speed matters
A slightly faster pace, around 1.1 to 1.2 times, often sounds more natural for short videos. Try a few values on a sentence before you generate the whole script.
Disclosure and rights
- Platforms may ask you to label AI-generated or altered audio. Follow the current rules.
- Clone only a voice you have the right to use, and never someone else's without clear permission.
