Multilingual Course Voiceover: One Script, Three Markets

The most expensive step in taking a course abroad is not translation, it is voiceover: a native instructor recording twenty lessons costs thousands. AI voiceover turns that into three generations of one script, and when a slide changes you regenerate only that lesson.

Instructor voices: one course, two teachers

A course voice should sound like a teacher: clear, steady, never theatrical. The confident male tech voice and the composed female voice both work; pick one lead per course and keep it.

The same passage in Chinese

The proof that export works is the side-by-side: one passage, two languages, the same instructor temperament.

Lock the terminology

Terms and acronyms that recur through a course are mispronounced everywhere if they are mispronounced once. Define them in the pronunciation dictionary before batch generation; typical failures are in fixing TTS mispronunciation.

Sync slides and subtitles

Generation returns word-level timestamps, so slide transitions can be aligned to sentences and the SRT drops straight onto the video. See the subtitle generator.

Cost

A 30-minute lesson is about 24,000 characters, roughly 1,700 credits on the standard model; twenty lessons in three languages is about 100,000 credits, well inside a Creator month. The full conversion is in how much AI voiceover costs per minute.
