Microsoft Edge can soon translate and dub videos in real time

Watching foreign-language videos usually means struggling with inaccurate auto-captions or waiting days for someone to upload subtitles.

At this year’s Build conference, Microsoft announced that Edge is getting built-in AI video translation. It will translate spoken audio on the fly, offering both live subtitles and full AI dubbing as the video plays.

Real-time dubbing right in the browser

The feature is set to roll out across popular platforms including YouTube, LinkedIn, Coursera, and major news outlets like Reuters, CNBC, and Bloomberg.

At launch, language support covers Spanish translated into English, plus English translated into German, Hindi, Italian, Russian, and Spanish. Microsoft says more languages and websites are in the pipeline.

Edge already uses Copilot to summarize YouTube videos, but that trick relied strictly on existing video transcripts. By processing the audio stream directly, this update handles raw speech on the fly and provides a helpful accessibility boost for deaf or hard-of-hearing viewers.

Why it matters

For anyone relying on Coursera for technical training or tracking international news streams, live translation eliminates the language barrier without requiring clumsy third-party extensions.

We think baking live dubbing directly into the browser is a brilliant move. Instead of waiting for creators to upload multi-language tracks, the client side does all the heavy lifting. The catch will be audio latency and natural cadence—if the AI voice sounds robotic or constantly trips over fast speech, users will likely switch back to plain text subtitles.
