You’ve put time, effort, and expertise into your webinars. They’re full of insights, delivered by your best minds, and carefully tailored to your audience. But if that audience only speaks one language – you’re limiting your impact.
In a global business environment, webinars shouldn’t be restricted by language.
They’re one of the most powerful formats for building trust, sharing knowledge, and guiding prospects.
With multilingual versions, your webinars become scalable content assets that reach across borders.
Most webinars are already recorded, edited, and structured. That makes them the perfect candidate for localization. Instead of producing ten new versions from scratch, you can reuse your core content – but make it work for every market.
Translated webinars allow you to:
Expand reach without extra production cost
Serve diverse customer groups across regions
Train international teams with unified content
Build a consistent global brand voice
And unlike subtitles, voice-based translation with proper lip sync keeps your content engaging and professional – especially in long-form formats.
There are many reasons to localize your webinar library – whether for marketing, education or internal communications:
Turning live webinars into on-demand content for international leads
Presenting product updates and demos to regional markets
Delivering training or onboarding to global teams
Supporting partners and resellers with clear, native-language content
Communicating leadership updates in a way that builds trust
If your webinar is worth doing once, it’s worth doing in ten languages.
Hiring voice actors, renting studio time, and syncing everything manually is time-consuming, expensive, and rarely scalable.
Subtitles can help – but they often don’t match the pace of speech, and become tiring for longer sessions. Worse, they break immersion and weaken the message.
Many AI tools also struggle with real-world webinars: multiple speakers, spontaneous phrasing, technical vocabulary, pauses, accents.
This is where most systems fail.
Dubly was designed to handle exactly these challenges. Our AI-powered platform can translate spoken content into over 30 languages – with high-quality audio, accurate lip sync, and support for even the most complex input.
Whether your webinar includes one or five speakers, scripted content or free-form discussion – Dubly delivers clean, natural-sounding results.
You can even choose to retain the original speaker’s voice, re-generated in the target language, for a truly seamless experience.

Automatic speaker separation, no need to pre-process
Accurate lip sync, even for long sessions
