Translating a course used to mean re-recording it, scene by scene, by a native voice actor in a studio. That cost $5,000–$15,000 per finished hour and took 6–10 weeks per language. AI translation with neural re-narration has changed that fundamentally — and 2026 is the year it became indistinguishable from human delivery for most subjects.
How it works
A modern course translation pipeline: extract the source transcript, machine-translate to target language with subject-aware glossaries, run a domain-trained QA pass, regenerate the audio with a neural voice tuned to the original speaker's timbre and pace, re-time captions, and re-render the video. The whole loop runs in hours, not weeks.
Languages that matter for global learners
For Indian institutions: Hindi, Telugu, Tamil, Kannada, Malayalam, Bengali, Marathi, Gujarati, Punjabi, Odia. For MENA: Modern Standard Arabic. For ASEAN: Bahasa Indonesia, Bahasa Malaysia, Tagalog, Vietnamese, Thai. For Africa: French, Portuguese, Swahili. DeepTech Course Translation can expose up to 196 target languages, subject to provider support.
Pick the right pilot
Start with one popular course and translate it into your single largest non-English learner segment. Measure completion rate and NPS before and after. The lift is usually 2–4x. Then scale.
