From online course platforms to universities and corporate academies – anyone offering digital education today is thinking globally. The demand for professional, high-quality video courses is growing fast. But when it comes to multilingual delivery, many providers hit a wall.
Traditional localization – using studios, voice actors, editors, and sound engineers – is expensive, time-consuming, and operationally complex. And subtitles alone often don’t cut it when you want learners to truly connect with and absorb content.
The solution?
AI dubbing with Dubly – built to localize educational video content at scale, with professional quality and full control.
Learning is based on language – and spoken language adds tone, clarity, and emotional connection. In many types of educational content, subtitles are not enough. Especially when the speaker is central to the message, like in:
Soft skills training
Coaching or leadership modules
Customer service education
Health & wellness topics
Motivational or behavioral learning
A course titled “Customer-Centric Sales Strategy” is originally recorded in German. It features:
On-camera trainers
Real-life examples and customer stories
Interactive scenarios
Subtitles can’t carry the trainer’s tone, pace, or nuance. Learners miss out.
→ A natural-sounding localized voice, ideally in sync with the speaker, makes all the difference.
With Dubly, entire courses and learning libraries can be translated and voiced over in 30+ languages – in just hours, not weeks. And if needed, with lip sync for maximum authenticity.
Video-based online courses
Screencasts and tutorials
Webinar recordings
Training content for internal academies
Explainer videos and animations
Certification-ready learning modules

Instead of producing courses from scratch for 15 markets, use your existing videos and simply localize them using Dubly.
→ New revenue streams, faster rollout, no studio dependency.
Students retain information more effectively when lessons are delivered in their native language and by voice, not just with subtitles. Especially for auditory learners.
Traditional dubbing can cost €50–100 per minute. With Dubly, AI dubbing starts at just €2–4 per minute.
→ Scalable even for smaller institutions and niche courses.
All translations can be manually reviewed and edited
Custom glossaries ensure accurate brand and domain-specific vocabulary
Add custom prompts to shape tone and delivery
Optional Native Speaker Control for sensitive or certified content
All data processed and stored on EU servers
US subprocessors only used under Standard Contractual Clauses (SCCs)
No training of general AI models on your content
Optional NDAs, TOMs, and DPA support available
Fully GDPR-compliant, ideal for education sector requirements
Results in just a few minutes
No credit card required
Best translation quality worldwide

Whether you're a university, an edtech startup, or an enterprise L&D team – scaling your learning content shouldn’t require a second production budget.
Dubly makes international delivery of educational video easy, fast, and effective.
