How to generate a voice over
The script does more work than the settings. These three steps are the loop, and rewriting in the first one fixes more problems than adjusting anything in the third.
- 01
Write for the ear
Short sentences, one idea each, and punctuation where a person would breathe. Text written to be read silently — long clauses, parenthetical asides, dense noun phrases — sounds wrong however good the voice is.
- 02
Choose a voice and keep it
Pick from the voice library, or save one so the same narrator carries a whole series. Switching voices between episodes is more noticeable to an audience than any single delivery flaw.
- 03
Generate, listen, adjust the words
Play it back against the picture. When a line lands badly, changing the sentence usually beats fighting the settings: commas, line breaks, and shorter clauses are the controls that matter most.
What makes generated narration usable
Voices that stay consistent
Save a voice and reuse it across every clip in a series, so a set of videos sounds like one channel rather than a rotating cast.
Delivery you can steer
Pace, emphasis, and pauses respond to how the script is punctuated and broken, which gives you real control over reads without a re-record.
Rewrites cost a minute
The reason to generate narration is not that it is cheaper than a voice actor — it is that changing one line on a Friday afternoon does not need anyone's calendar.
Under your own footage
The video you generated and the narration you generated live in the same library, on the same credits, ready to be cut together.
Several reads to choose from
Generate two or three versions of a line and pick the one that fits the picture, instead of taking the first result because a second costs another session.
Multiple languages
Localise a script by generating the same narration in another language rather than commissioning a separate recording for each market.
What people narrate
Product explainers
A clear read over a screen recording or a generated demo, updated whenever the product changes.
Short-form video
Voice over the hook and the payoff for social video, in the tone the platform's audience expects.
Ads and promos
Several script variants read the same way, so a campaign can test copy without booking a session for each.
Training and internal comms
Narration for material that gets revised often enough that human recording never stays current.
Audio descriptions
Spoken description tracks that make video usable for people who cannot see the screen.
Localisation
The same script in another language, matched to the same edit.
Writing a script that a synthetic voice reads well
The gap between a voice over that sounds generated and one that does not is mostly in the writing. Synthetic voices are excellent at reading a sentence and poor at inferring intent across a paragraph, so anything that requires the reader to hold a long structure in their head — a subordinate clause four commas deep, a sentence whose subject arrives at the end — comes out flat. Breaking the same content into shorter sentences fixes it without changing the meaning.
Punctuation is the closest thing to a direction track. A full stop is a longer beat than a comma; a line break is longer still. If a line is being rushed, the fix is usually to give it its own sentence rather than to reach for a speed control. If two ideas are running together, a full stop separates them more convincingly than any emphasis setting.
Numbers, acronyms, and names deserve a pass of their own. Write them the way they should be said — '2026' as 'twenty twenty-six' if that is the read you want, an acronym spelled with spaces if it should be spoken as letters. This costs a minute and removes the single most common reason a take has to be redone.
Finally, generate against the picture, not in isolation. A read that sounds good on its own is often a beat too slow once it is under a cut, and the only reliable way to know is to lay it in. Because regenerating a line takes seconds, it is practical to write the narration to the edit rather than editing to fit the narration.
AI voice over FAQ
- Is the voice over free?
- Yes, within your free credits. Audio runs are priced from the same balance as image and video generation, and paid plans add more credits and watermark-free exports.
- Can I use my own voice?
- You can save and reuse voices in the studio. Cloning anyone's voice requires their agreement — using a real person's voice without it is against the terms of service.
- What languages are supported?
- The voice library covers the major languages the product ships in, and the available set is shown when you pick a voice. Script and voice should be in the same language for a natural read.
- How long can a script be?
- Long scripts are best generated in sections — a paragraph or a scene at a time. It gives you finer control over pacing and means a single bad line does not cost a full regeneration.
- Can I use it commercially?
- Yes, under the terms of service, on a paid plan — the same terms as generated video and images.
