WHAT TO TAKE INTO YOUR PILOT
A specialist course needs consistent terminology and a subject review, alongside faster production.

THE REAL CHALLENGE
A translated lesson still has to teach.
Course localization is a learning-design task as much as a language task. A fluent voice is only useful when the terminology, explanation, and visual demonstration still lead learners to the same understanding.
01 Choose a representative lesson
An introductory welcome video rarely reveals the real review effort. Include specialist vocabulary, a worked example, and the instructor’s normal speaking pace in your pilot.
02 Separate language review from academic review
A native speaker can check naturalness; a subject expert checks whether an explanation is still correct. Assign both responsibilities before translating the wider course.
03 Plan for the next course update
A revised slide or demonstration can affect narration, subtitles, and multiple language versions. Keep the lesson identifier and source version with every exported file.
DECISIONS IN PRACTICE
Perso Dubbing brings the translation workflow into one place. Check the AI-reviewed result, edit any terms or explanations that need adjusting, and apply your changes to regenerate the translation and dub.
WHAT PERSO DUBBING HANDLES
Perso Dubbing handles speech recognition, translation, dubbed voice generation, and subtitles for recorded lessons in one workflow. The AI translation model translates and reviews at near-real-time speed. You check the result and edit any corrections in the script editor. Applying those changes regenerates the translation and dubbed audio with your corrections.
FROM SOURCE TO APPROVED VERSION
From One Lesson to a Reviewed Language Version
01 Select a Pilot Lesson
Choose a lesson with typical terminology and visuals. Set the target language and identify who will review the translation.
Prepare a lesson ID, source file, target language, and a working terminology sheet.
02 Translate and Review
Perso Dubbing handles speech recognition, AI translation and review, dubbed audio, and subtitles in one workflow. Check the result and edit anything that needs correcting in the script editor.
Apply your changes to regenerate the translation and dubbed audio, then check the updated result.
03 Export and Publish
Download the approved video and subtitle files, upload them to your learning platform, and collect learner feedback before expanding.
Record the approved version and test the uploaded lesson in the learning environment.
