How to add an AI voiceover to a video
4 min read · Updated October 24, 2026
An AI voiceover reads your script in a natural voice, so you can narrate videos without recording yourself. Here's how to get one that doesn't sound robotic, and how to put it on a video.
Make an AI voiceover →Write for the ear
- Short sentences; one idea each.
- Write numbers and abbreviations the way they're said.
- Read it aloud once — anything you stumble on, the voice will too.
Pick and tune the voice
Choose a voice that fits the content — warm for stories, clear and firm for explainers — then tune it. Slightly faster than normal speech suits short-form; lower the pitch a touch for a calmer tone. Listen before you commit.

Listen and use it
Hear it first, download the audio, or drop it straight into a video in Zlayo's editor.
Put it on your video
In Zlayo's editor, put the voiceover under your video, trim the video to match, and add captions written from the voiceover so it reads with the sound off. Or use the Reddit story and fake text makers, which narrate for you.
Questions
No. Voiceovers are on Zlayo's paid plans, from $19 a month, and they don't use your monthly minutes.
Yes, clone it in Voice Studio and pick it like any other voice.
Write short spoken sentences, pick a natural voice, and adjust speed and pitch slightly rather than using the defaults.
