How to Manage Live Captions Language Files in Windows 11 Accessibility Settings

Live Captions in Windows 11 uses language-specific speech-recognition files. Here is how to switch, add, troubleshoot, and remove them, and what Microsoft says about on-device processing.
Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Live Captions in Windows 11 does not expose a model manager. Each caption language depends on a speech-recognition language file that Windows downloads to the PC, and you add, switch, or remove those files from the Live Captions window or from Windows language settings. Microsoft documents the current flow for Windows 11 version 22H2 and later, and a separate older route for version 23H2 and earlier. This guide covers both, plus the privacy behavior, translation requirements, and download fixes.

What “language models” means in Live Captions

The “language models” in Live Captions are the language-specific speech-recognition files that turn audio into text on your device. Microsoft’s own controls call them language files or speech recognition for a language, and they are not a general-purpose model you can tune. You cannot choose a model version, adjust recognition parameters, or swap in third-party engines from the Live Captions settings. What you can do is pick which installed language Live Captions uses, download a missing one, and remove one you no longer need.

Turn on Live Captions

Live Captions is a built-in accessibility feature, and Microsoft’s Live Captions help article lists four ways to open it:

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.
  • Windows key + Ctrl + L, the direct shortcut.
  • Quick Settings, then the Accessibility tile.
  • Start > All apps > Accessibility > Live captions.
  • Settings > Accessibility > Captions.

On first launch, Windows asks you to consent to processing voice data on the device and offers to download the language files it needs. If your preferred language is not available, Microsoft says you can use another language during setup and change it later.

Change the caption language on Windows 11 22H2 and later

Use this route when the Live Captions window has a Settings button and a Change language option. Microsoft documents it as the current flow.

  1. Open Live Captions with Windows key + Ctrl + L.
  2. Select the Settings button in the Live Captions window.
  3. Select Change language and choose the language you want.
  4. Select Continue. If the language is not installed, confirm Download.
  5. Wait until Live Captions indicates it is ready in the selected language.

In the language selector, languages that are already installed appear in bold. A language that is not bold needs to be downloaded before it can be used for captions.

Add a caption language on Windows 11 23H2 and earlier

Microsoft’s support article documents a separate path for version 23H2 and earlier. The two routes differ in where they start and in the installation step, so check which one your PC shows before you follow either.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.
Item Current flow (22H2 and later, as documented) Older flow (23H2 and earlier)
Starting point Live Captions window > Settings > Change language Live Captions Settings > Caption language > Add a language
Where the language is installed Downloaded from the Change language prompt Settings > Time & language > Language & region > Preferred languages > Add a language
Speech feature to select Not required as a separate step in the documented flow Install speech recognition for the language, with Enhanced speech recognition selected when that option appears
Result Language becomes active for Live Captions after the download finishes Installed language becomes available in Live Captions

If you are unsure which version you run, press Windows key + R, type winver, and press Enter. If your Live Captions Settings show Caption language rather than Change language, follow the older flow.

  2. Select Caption language, then Add a language.
  3. Open Settings > Time & language > Language & region > Preferred languages > Add a language.
  4. Choose a language that supports speech recognition, then select Enhanced speech recognition when that option appears and install it.
  5. Return to Live Captions and choose the newly installed language.

Microsoft notes that speech features are not offered for every language, so a language missing from the list may simply lack speech support on your PC.

Caption language versus translation

Live Captions transcribes speech in the language you select. Translation is a separate capability. Microsoft says translation is available on Copilot+ PCs running Windows 11 version 24H2 or later, and it translates speech into English (United States) or Simplified Chinese depending on the output language you select. On a PC that does not meet those requirements, selecting a caption language still works, but translated output is not offered.

Microsoft’s current support article states that the feature translates more than 40 languages into English and 27 into Simplified Chinese. The article does not give a publication date for those counts, so treat them as current capability claims rather than dated statistics, and expect them to change with later updates.

Privacy: where processing happens

Microsoft’s Live Captions help article states: “Audio, voice data, and captions never leave your device and are not shared to the cloud or with Microsoft.” The same article says processing and caption generation happen on the device, and that generated captions are not stored on the device or in the cloud. This is Microsoft’s description of the product’s behavior. It is not an independent audit, and it covers Live Captions as documented; other apps that capture the same audio follow their own policies.

Include microphone audio

By default, Live Captions only captions sound playing from the PC. To caption speech picked up by your microphone, open the Live Captions window’s Settings and go to Preferences > Include microphone audio. This option is off by default.

  • Overlap: When device audio and microphone audio overlap, Microsoft says device sound is prioritized. In a meeting, your own speech may not appear while a remote participant is talking.
  • Microphone access: Microphone privacy is controlled under Settings > Privacy & security > Microphone > Let desktop apps access your microphone.
  • Accuracy: Microsoft recommends minimizing background noise and speaking directly into the microphone.

Caption appearance and position

Caption style controls how captions look, not how they are recognized. Go to Settings > Accessibility > Captions to choose a built-in style or select Edit to customize one. To move the caption box, open the Live Captions Settings and choose Position, then select above, below, or floating over the screen.

Fix language download errors

If Windows reports that required language files cannot be downloaded, work through these checks in order:

Free tools Windows power users keep installed

One-click scans. No signup required.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.
  • Connectivity: Confirm the PC is online and can reach the internet.
  • Microsoft Store: Open Microsoft Store and confirm it can download apps. Setup can depend on access to its catalog.
  • Managed PCs: On an enterprise or school device, Store access may be disabled. Ask IT whether the matching speech package can be deployed to the PC.
  • Package match: Microsoft identifies display language and system type as the inputs for choosing the correct package. Follow the installation steps and troubleshooting notes on Microsoft’s live troubleshooting page for Live Captions or voice access setup issues. Do not install language files from unofficial sites.
  • Feedback: If Store downloads work but Live Captions setup still fails, send feedback through Feedback Hub.

Microsoft’s troubleshooting page lists package examples by language and architecture. Those names and availability can change, so use the live page rather than a copied list.

Remove language files to reclaim storage

Language files take up disk space. If you no longer use a caption language, Microsoft says you can remove it:

  1. Open Settings > Apps > Installed apps.
  2. Search for Speech Pack.
  3. Select the More menu (three dots) next to the language package you want to remove, then select Uninstall.

Removing a language file does not change your other Windows language settings. If you later want that language back in Live Captions, download it again from the Change language prompt or the older Add a language route.

Historical language additions

Microsoft’s May 24, 2023 Windows configuration update listed Live Captions language additions for Windows 11 version 22H2, including Chinese (Simplified and Traditional), French (France and Canada), German, Italian, Japanese, Portuguese (Brazil and Portugal), Spanish, Danish, English (Ireland and other dialects), and Korean. That list is a dated historical record, not the current inventory. Check the language selector on your own PC for what it offers now.

A microphone is not required to change caption language, and this guide does not recommend a specific device.
