Languages and voices

How a video speaks several languages and stays one video.

Master and translations

Every video has a master version in the UI language of your app. Translations are generated from the master script; the timing is recalculated per language while the picture stays identical.

Languages

At launch: English (US and AU), Spanish (Spain and Latin America), German and French. Chapters and captions come along in every version; there are no subtitle-only languages.

Voices

Three to four curated voices per language, at least one male and one female. A brand voice per language applies to your organization and can be overridden per video. No voice cloning, no background music.

Edits

When a sentence changes, only the affected passage is re-voiced; the rest of the track stays untouched. Audio regenerates when you ask for it, never on every keystroke.

In the player

Viewers switch language inside the embed player; chapters and captions follow.
