AI voice-overs for video ads
Performance advertising is an iteration game: the winning ad is usually the twelfth variant, not the first. But re-recording a voice track for every hook, offer and call-to-action is exactly the friction that keeps teams testing three variants instead of thirty. Generated voice tracks make the variant matrix cheap — change one line, regenerate one paragraph, export a fresh cut in minutes.

129/500Delivery stays constant while the message changes. Every variant renders with the same voice, pacing and loudness, so your split test actually measures the copy — not the difference between two studio sessions. And because unchanged paragraphs replay from cache, iterating on a hook costs only the sentences you touched.
Bulk mode fits ad workflows naturally: a CSV with one row per variant returns a zip of ready-to-edit tracks for your video editor, and a failing row is refunded on its own instead of blocking the batch. Need the same campaign as a Spanish or German ad set? The narrator you already picked speaks those too.
No signup needed — the demo speaks up to 500 characters.
How it works for video ads
- 1
Write the base script once, then duplicate rows in a CSV and vary only the hook, offer or call-to-action per variant.
- 2
Pick one voice for the whole campaign so every A/B cell sounds identical except for the words.
- 3
Generate the batch and pull the zip into your editor — tracks arrive loudness-normalized, ready to sit under the visuals.
- 4
When a variant wins, iterate on it: edit a paragraph and regenerate just that line for the next test round.
Built for video ads
A variant matrix, not a studio calendar
Thirty scripts in a CSV become thirty finished tracks in one batch — no sessions to book, no retakes to schedule, no waiting on talent availability.
Same voice in every cell
Split-test results stay clean when delivery is constant: one voice profile and one loudness target across every export in the campaign.
Pay for the diff
Changed the call-to-action but kept the hook? Cached paragraphs replay free — only the sentences you actually edited are charged.
Localized ad sets
Voice the same campaign for other markets in the languages your audience speaks, keeping the narrator you already chose.

Questions, answered
Can I generate dozens of ad variations at once?
Yes — bulk mode takes a CSV with one row per variant (filename, script, optional voice) and returns a zip of finished tracks. Rows fail and refund individually, so one bad script never blocks the rest of the batch.
Will every variant sound identical apart from the words?
That's the point: the same voice profile, speed setting and loudness normalization apply to every generation, so your split test measures the copy rather than recording-session differences.
What format do the tracks come in for my editor?
MP3 or WAV, loudness-normalized so they sit at consistent levels under your visuals. A timed caption file can be exported alongside each track when a placement needs subtitles.
Do ad platforms allow synthetic voice-overs?
Synthetic narration is broadly used in ads, but policies differ by platform, region and vertical — check the current rules for the specific placement you're buying before launch.
How fast can I turn around a new offer?
Minutes, in practice: paste the updated script, regenerate the paragraphs that changed, and export. Unchanged paragraphs replay from cache, so a price-drop rewrite costs almost nothing.
