Natural voices generated from text, lips synced to what is actually said, and one-click dubbing of the same video into more than 100 languages.
In short: the voice decides whether an AI avatar video gets watched to the end. The text of each scene becomes a natural voice, with a tone, pace and accent you choose, and the avatar’s lip movement is synced to what is actually spoken. More than 100 languages are available, so the same script can be delivered in Romanian, English, German or Spanish without rebuilding the video. Dubbing closes the loop: it translates the script, generates the voice in the new language and re-syncs the lips, keeping the same scenes and the same edit.
Every scene carries its own text, which is turned into audio using the voice chosen in the video settings: tone, gender, speaking pace, language and accent. The voice does not read mechanically — it respects punctuation, pauses at the end of a sentence and emphasizes whatever you marked as important. You can listen to the result on a single scene and adjust the pace or the pauses before the full render.
Once the voice is generated, the platform matches the avatar’s lip movement to the sounds actually spoken, not to the raw text. That is why the sync stays correct when the same script is delivered in another language, with a different syllable structure. The result is a presenter that appears to be speaking, not an image with an audio file pasted over it.
An existing video can be dubbed into another language without rebuilding it: the platform translates the script, generates the voice in the new language, re-syncs the lips and rewrites the subtitles. The scenes, the edit and the brand elements stay identical, so you get the same information for another market in minutes rather than days. The translation stays editable — you can correct it against your internal terminology before rendering.
Brand names, abbreviations and technical terms are where generated voices most often get it wrong. That is what the account-level pronunciation dictionary is for: you write how a term should be read, and every future video says it correctly. You can also add targeted pauses or emphasis directly in the scene text.
More than 100, with several voices and accents available for the most used among them.
The platform translates the script of an existing video, generates the voice in the new language, re-syncs the lips and rewrites the subtitles, keeping the same scenes.
Yes. The translated script stays editable before rendering, which matters for internal terminology and product names.
Yes, because it is calculated on the sounds actually spoken in the new language, not on the original text.
Yes, through an account-level pronunciation dictionary: you write how the term should be read and every future video says it that way.
Yes. The audio preview runs on a single scene, so you can compare two voices or two paces without spending render time.
Generate the voice from text, check the lip sync on one scene, and dub the same video into another language in one click.
The voice is generated from the scene text, the avatar’s lips sync to what is actually said, and dubbing translates the same video into another language in one click.
Being straight with you — here is where 4avatars is not yet the best choice:
A fit when the same material has to ship in several languages without rebuilding the video for each market. Not a fit if you need an actor’s performance rather than clear, consistent delivery.
