Stop staring at subtitles. Start actually learning.
You open a Udemy course. The instructor explains complex concepts while showing code, diagrams, or spreadsheets on screen. But you can't watch the screen AND read subtitles at the same time. You're forced to choose — miss the visuals or miss the explanation. Either way, you lose.
Video Translator for Udemy — Unlimited AI Voice Dubbing solves this completely. Instead of translating subtitles, it generates actual voice dubbing in your native language. You hear the lecture. You watch the screen. You learn — the way it was meant to be.
⚡ Unlimited dubbing. No minute caps. No monthly subscription. Most dubbing tools give you 15 free minutes, then charge $19–$129 per month with strict hourly limits. Every lecture costs you money. Every course drains your balance.
This extension works differently. Free users get unlimited dubbing with Local TTS — no minute caps, no timers, no monthly reset. PRO users get unlimited real-time dubbing with premium voices for a one-time payment. Learn one course or a hundred — the price stays the same.
🚀 Get started in 60 seconds
That's it. No accounts, no complicated setup. Open a course → pick your language → listen.
What makes this voice translator different
🎙️ Real AI voice dubbing, not just text Other tools give you translated subtitles. This extension acts as a true voice to voice translator — you hear the lecture spoken in your language. The AI dubbing synchronizes with the video, so the pace and timing feel natural.
🔓 Unlimited listening — free and PRO No minute caps. No hourly quotas. No monthly limits that reset. Generate dubbing for any lecture and listen as many times as you want. Your dubbed audio is cached locally — replay instantly without regenerating. Other services charge per minute of dubbing. Here, you pay once (or nothing at all) and listen forever.
🌍 Works as your personal video language translator Whether you need an english to spanish voice translator for a business course, a chinese to english translator voice for a tech tutorial, or want to translate vietnamese to english voice for any lecture — this online video translator handles it. Supports multiple language pairs for real voice to voice translation app experience.
⚡ Two powerful modes
Real-Time Dubbing (PRO): Start listening immediately. The real time translator engine generates audio segments on the fly — first segments are ready in seconds, and the rest generate while you listen. True real time translation with minimal wait. Unlimited — no per-minute charges.
Local TTS (Free & PRO): Generate full dubbing for the entire lecture. Takes a few minutes, but once generated, the dubbed audio is cached locally. Replay any lecture instantly without regenerating. Perfect for courses you revisit. Completely free with no listening limits.
🔒 Your translations stay with you Generated dubbing is saved in your browser. When you rewatch a lecture, the translate video audio loads instantly from cache — no waiting, no re-processing. No cloud servers tracking your minutes.
Why not a subscription dubbing service?
Subscription tools charge $19–$129/month and cap your usage at 7–60 hours. For a 40-hour Udemy course, you'd spend $39–$69 per month for weeks. That's $100+ just to finish one course.
