Most Windows 11 Users Don't Know Copilot+ Can Translate Live Audio On-Device
Copilot+ PCs can turn any video, meeting, or podcast into live translated captions — processed entirely on your device, never touching the cloud.
01. What It Is
Windows 11 has a built-in Live Captions feature that automatically generates subtitles for any audio playing on your PC — a YouTube video, a Teams call, a podcast, even a local media file. Basic captioning has been around since Windows 11 version 22H2 and works on ordinary hardware.
The hidden superpower arrives on Copilot+ PCs: those same captions can be translated in real time. Audio spoken in one of 40+ languages appears as English captions on the fly, or as Chinese (Simplified) captions on Snapdragon Copilot+ devices. The catch that makes it remarkable is where the work happens — the translation runs locally on the machine's NPU (neural processing unit), so nothing you watch or hear is uploaded to any server.
Because it's a system-level accessibility feature rather than an app, it works across everything: browsers, media players, video conferencing tools, and streaming services. You don't paste text anywhere or pause to search a translation — the captions simply keep up with whatever is playing.
Why It Matters
Instead of pausing a foreign-language video to copy-paste sentences into a translator, you get continuous translated subtitles in real time. It unlocks meetings with international colleagues, foreign news and lectures, and untranslated media — all privately, since the audio never leaves your device. For anyone who regularly juggles languages, it replaces a clunky manual workflow with a silent, automatic one.
Who Can Benefit
- People who watch foreign-language videos, lectures, or news
- Remote workers in multilingual meetings and calls
- Language learners who want live subtitles while listening
- Privacy-conscious users who don't want audio sent to the cloud
- Deaf and hard-of-hearing users who also need translation
02. Step-by-Step Guide
- 1
Confirm you have a Copilot+ PC
Real-time translation requires a Copilot+ certified PC with an NPU rated at 40 TOPS or higher, running Windows 11 version 24H2 or later. Basic (non-translated) captions work on any Windows 11 22H2+ PC, but translation does not.

Set your device language correctly
Translation only works when your Windows display language is set to English (United States) or Chinese (Simplified). The feature translates INTO one of those languages — it does not translate from English into other languages.

Turn on Live Captions
Use any of these: press Windows + Ctrl + L; or go to Settings > Accessibility > Captions and toggle Live captions ON; or open Quick Settings on the taskbar > Accessibility flyout > Live captions; or Start > All apps > Accessibility > Live captions.

Download the language components
The first time you enable translation, Windows may prompt you to download the on-device speech and translation packs. Let them finish installing — after that, everything runs offline.

Choose the source language and play audio
In the Live Captions bar, open its settings to pick the spoken language you want translated. Then play your video, call, or podcast — translated captions appear in the caption bar automatically.
Pro Tips
- Reposition the caption bar to the top or bottom of the screen, or float it, from the Live Captions settings menu so it doesn't cover what you're watching.
- On AMD and Intel Copilot+ PCs the feature supports 44 languages into English only; Snapdragon Copilot+ devices add 27 languages into Chinese (Simplified).
- Everything is on-device, so it keeps working with no internet connection once the language packs are installed — useful on flights or in low-connectivity settings.
Warnings & Limitations
- Real-time translation requires Copilot+ hardware (NPU ≥40 TOPS) and Windows 11 24H2+ — it is not available on standard PCs, though basic captioning is.
- Switching languages while audio is still playing can crash Live Captions. Stop or pause the audio first, then change the language.
- As of late 2024 the feature was still rolling out via the Dev Channel for AMD/Intel Copilot+ PCs; Snapdragon devices had earlier access. Availability may vary by device and update.
- It translates only INTO English or Chinese (Simplified) — it cannot translate from English into another language.
