The brief
An ed tech platform with an existing library of English lesson videos wanted to expand into several regional languages, but re shooting the entire library with new presenters in each language was not realistic on time or budget.
How we would approach it
Start with a pilot set, not the full library
Rather than localizing everything at once, a representative pilot set of lessons across different subjects and formats, to confirm quality, pacing, and student response before committing to the full catalogue.
Adapt scripts for the language, not just translate them
A direct translation often changes pacing and loses idiom that matters for a teaching context, so scripts would be adapted for natural phrasing and correct pacing in each target language before voiceover generation, not translated word for word.
Match on screen text and visuals to the new audio
Any on screen captions, labels, or graphics in the original videos reviewed and updated to match the localized audio, since mismatched text and voice undermines trust in an educational product faster than almost anything else.
Build a review step with a native speaker before publishing
Every localized lesson reviewed by a native speaker familiar with the subject matter before it goes live, catching pacing or terminology issues that are difficult to hear without that context.
What this approach is built to deliver
A path to expanding the existing library into new languages at a fraction of the cost and time of re shooting, with a quality check built in so speed does not come at the expense of trust in the educational content.
