An AI voice-over for your corporate videos
Product demos, onboarding videos, brand films, trade-show loops: these videos get rewritten often and re-recorded rarely. A synthetic voice fixes the problem at the root. Here is how to use one without anyone noticing.
The formats it suits
Product demos first: a precise script, technical terms, an update with every release. Onboarding and internal communications next: content that lives a long time, where a consistent voice reassures. Then explainer videos, and the silent loop on a trade-show stand that needs a short, calm narration that reads through the noise. For short social formats, the AI voice for TikTok and Reels guide takes over; for training content, voice-over for e-learning.
Pick a tone, then keep it
For a demo or a brand film, Paul Confident in English and Marie Neutre in French deliver the quiet assurance you expect from a corporate voice. Marie Enjouée suits welcome videos, less so financial announcements. Listen to the samples on the voices page: they all read the same text, so the comparison is fair. Once chosen, write the tone into your video guidelines. The consistency of a ten-film series hangs on that detail: same voice, same tone, same punctuation rhythm.
One script, an English version and a French version
Teams publishing in two languages gain the most. The English script and its translation go through the voices of each language, with similar durations, without booking two actors or two studios. Numbers, acronyms and product names are checked once per language, then the chosen spelling is frozen for the whole series; the writing rules are in the article writing a script for an AI voice.
Fix one sentence without redoing the film
The price changed, a feature was renamed, legal wants a nuance: you regenerate the sentence in question, in the same voice, and drop it back into the edit. The rest of the film does not move. One generation covers 1,500 characters, about a minute and a half; split your scripts by sequence, one file per shot, and replacements become surgical. The counting rule is simple: every character counts, spaces and punctuation included, and credits are only charged when the audio is produced.
Editing: a dedicated track, music underneath
In Premiere, DaVinci Resolve, CapCut or After Effects, import the MP3 or WAV on a track dedicated to the voice, then cut your shots to the narration rather than the other way round: the voice sets the pace. WAV is better if you apply processing; MP3 is enough for a simple edit. Keep the music bed around −18 dB under the voice so it stays intelligible on a phone, and leave half a second of silence before the first sentence. The YouTube voice-over guide details these settings.
Get sign-off without the wait
Review by management, marketing and legal is the real bottleneck of a corporate video. With a synthetic voice you produce three variants of an opening line in minutes, play them, keep the one that lands. A trial costs its characters, not a studio day. To understand what the engine does well and where it hits its limits, read the AI voice generator page.
Rights and transparency
Commercial use comes with paid credits: your videos can be published, sold or bundled into an offer, as the FAQ on usage rights explains. The European AI Act asks you to inform the public when synthetic content could be mistaken for the real thing: a line in the credits or the description is enough, and every MP3 carries a technical marker in its metadata. The case-by-case detail is in the article AI voices: rights and obligations.
What it costs
A three-minute film is about 3,000 characters, €0.27 with the €9 pack of 100,000 characters, valid for twelve months. A ten-video series comes to €2.70. A team producing continuously, demos, onboarding, internal comms, fits in the Medium subscription at €14.99 a month for 200,000 characters. The plans are on the pricing page.
