Course Translation Software for Multilingual Online Learning
Reach learners in their native language. DeepTech translates entire courses — video, transcripts, slides, quizzes, certificates — into 60+ languages, in minutes.
Quick answers
- How does AI course translation work?
- DeepTech transcribes the source video, translates the transcript with a domain-tuned model, re-renders the audio in a natural target-language voice that matches the original speaker's pacing, and burns updated subtitles. Slides, quizzes and certificates are translated in parallel so the entire course ships as one localised package.
- How many languages are supported?
- Over 60 languages including English, Spanish, French, German, Portuguese, Arabic, Hindi, Telugu, Tamil, Bengali, Marathi, Mandarin, Japanese, Korean, Indonesian, Vietnamese, Swahili and most major European and Asian languages.
- Is the translated voice the original instructor's voice?
- Optionally yes. Instructors who opt in can record a short voice sample; the system then synthesises target-language audio in a voice that closely matches their own timbre. By default a high-quality neutral voice in the target language is used.
- How accurate is the translation for technical subjects?
- DeepTech uses domain-aware glossaries (engineering, medicine, law, IT) and lets instructors lock specific terms before translation. Output quality on technical content typically reaches 85–95% before human review and is intended to be reviewed by a subject-matter speaker prior to publishing.
- Do translated courses stay in sync when the original is updated?
- Yes. When the source course is edited, DeepTech re-translates only the changed segments and updates the localised versions, preserving versions and timestamps so learners always see the latest content in their language.

Course translation questions
What is course translation software?
Course translation software automatically converts an online course — videos, transcripts, slides, quizzes, certificates, and platform UI — from one language into one or more target languages, preserving timing, layout, and learning objectives.
How accurate is the AI translation?
DeepTech uses a combination of large-language-model translation, domain-specific glossaries (engineering, medicine, law, cybersecurity), and human-in-the-loop review. Out-of-the-box accuracy averages 92–96% for technical content; institutions can edit any translation before publish.
Does it translate the spoken video too?
Yes. The original voiceover is transcribed, translated, and re-narrated with a natural AI voice matching the lesson's pacing. On-screen text and slides are translated in place. Original speaker preservation (voice cloning) is available as an enterprise option.
Which languages are supported?
60+ languages, including all 10+ major Indian languages, Arabic (with RTL), French, Spanish, Portuguese, German, Mandarin, Bahasa Indonesia, Tagalog, Vietnamese, Thai, Swahili, and more. New languages added monthly.
Can learners switch languages mid-course?
Yes. The learner picks their preferred language on first login; they can switch at any time and resume the same lesson in the new language, with progress preserved.
How is it priced?
Included in DeepTech Enterprise and white-label plans. Pay-per-language top-ups on Pro plans. See pricing for details.
