You’ve invested time and expertise into creating a solid online course.
The content is strong. The structure works.
But what about all the learners who would benefit from your material – if only they could understand it?
Translating your video-based courses is the smartest way to:
Reach new international audiences
Empower global employees
Increase course completion rates
Make knowledge truly accessible
And here’s the good news: You no longer need studios, voice actors, or weeks of editing to do it.
Dubly allows you to translate your e-learning content into 30+ languages – fast, reliably, and in high quality.
Online learning is growing – globally.
Whether you're a business training your team, a platform provider, or a solo creator, multilingual video content brings powerful benefits:
Grow into new markets
Improve accessibility for your current users
Train international teams with unified content
Increase understanding and engagement
Boost your professional image with polished, localized materials
Studies show: People learn better in their native language – especially when dealing with complex or technical content.
Translating e-learning videos used to be a major production task:
Extract the script
Translate it
Book voice talent
Record in a studio
Re-edit the video
Sync everything manually
And repeat… for every video, and every language.
It’s expensive, time-consuming, and rigid – especially if your content changes frequently or you manage a large library.
Dubly simplifies the process – without compromising on quality.
You upload your video, select a language, define a few settings… and Dubly does the rest:
Upload your video
Select your target language and choose your settings (e.g. number of speakers, glossary use)
Dubly generates the translated voiceover with natural-sounding AI voices
Automatic lip sync is applied – for a truly polished result
Download your video – or edit the translation as needed
You stay in full control. Edit translations, apply terminology preferences, even submit videos for native speaker review if required.
Choosing the right languages is key. Ask yourself:
Where is your target audience located?
Which new markets are you planning to enter?
**Do you already have international teams or users you want to support?
**
Common e-learning languages include:
English
Spanish
German
French
Portuguese
Polish
Arabic
Turkish
Dubly currently supports 30+ languages, with more being added regularly.
To get the best results, we recommend:
✅ Clear audio and speaker separation
✅ Define your key terminology – use a glossary
✅ Indicate if multiple speakers are involved
✅ Avoid overlapping voices or heavy background music
✅ Use Native Speaker Review for high-stakes or regulated content
The good news: With Dubly, you can edit translations directly – so nothing is ever “locked in.”

Absolutely – and here’s why:
Dubly is purpose-built for professional video translation. Unlike general AI platforms, we focus specifically on voice quality, timing accuracy, and realistic delivery.
You get:
🎙 Natural, expressive voices – not robotic text-to-speech
🧠 Custom glossaries to ensure accurate and brand-consistent translations
👄 Automatic Lip Sync – so the video looks right, not just sounds right
