Live captions in Teams show real-time text for what is said during a meeting. When they fail to start, you see no captions area or a blank captions panel. This usually happens because the language is not supported, a policy blocks captions, or the Teams app has a corrupted cached state. This article explains the root causes and gives step-by-step fixes for Windows 11.
You will also learn how to check your Teams policy settings and how to reset the app cache. The fixes work for both the classic Teams and the new Teams app. Follow the steps in order until captions start working.
Key Takeaways: Fix Teams Live Captions Not Starting
- Teams admin center > Meetings > Meeting policies > Live captions: Enables or disables the live captions feature for all users.
- Teams > Settings > Captions and transcription: Turns on live captions for your own meetings and sets the spoken language.
- Ctrl+Shift+C: Toggles live captions on and off during a meeting without using the menu.
- Windows 11 > Settings > Time & Language > Language & region: Adds the English (United States) language pack, which is required for captions to work.
- Teams cache folder (%appdata%\Microsoft\Teams): Clearing this folder fixes corrupted state that can stop captions from starting.
Why Teams Live Captions Do Not Start on Windows 11
Live captions rely on cloud-based speech recognition. The Teams app sends audio to Microsoft servers, which convert the speech to text and send it back. If your Teams admin has disabled the live captions policy, the captions button appears grayed out or missing. If the language spoken in the meeting is not in the supported list, captions will not start at all.
On Windows 11, another common cause is a missing language pack. Teams uses the Windows language settings to determine the default caption language. If the meeting language does not match any installed language, the captions service cannot process the audio. Finally, a corrupted Teams cache can prevent the captions feature from loading properly.
How the Live Captions Feature Works
Live captions appear at the bottom of the meeting window. They are available only for meetings where the organizer or the tenant allows them. The captions are generated in real time and are not saved unless you also enable transcription. The feature supports several languages, including English, Spanish, French, German, and Chinese.
Prerequisites for Live Captions
Before you try any fix, confirm these requirements:
- You are using the Teams desktop app on Windows 11.
- Your Teams version is up to date.
- Your admin has enabled live captions in the meeting policy.
- You are not using a guest account in the meeting.
- The meeting audio is clear and not muted by the speaker.
Steps to Fix Live Captions Not Starting in Teams
Follow these steps in order. After each step, test whether captions start in a test meeting.
- Check if your admin has enabled live captions
Open the Teams admin center at admin.teams.microsoft.com. Go to Meetings > Meeting policies. Select your policy and look for the Live captions toggle. If it is off, turn it on and save the policy. Wait 10 minutes for the policy to sync, then restart Teams. - Turn on captions in your Teams settings
In Teams, select your profile picture at the top right. Choose Settings > Captions and transcription. Turn on the toggle for Live captions. Confirm that the spoken language matches the meeting language. If not, change it to the correct language. - Install the English (United States) language pack on Windows 11
Open Windows 11 Settings > Time & Language > Language & region. Under Preferred languages, select Add a language. Choose English (United States) and install it. After installation, set it as the display language if possible. Restart your computer. - Update Teams to the latest version
In Teams, select your profile picture > Check for updates. Teams will download and install any pending update. Restart Teams when the update finishes. - Clear the Teams cache
Close Teams completely. Press Ctrl+Shift+Esc to open Task Manager. End all processes that show Microsoft Teams. Open File Explorer and type %appdata%\Microsoft\Teams in the address bar. Delete all files and folders in that directory. Do not delete the Teams folder itself. Restart Teams and sign in again. - Test captions in a meeting
Start a new meeting with yourself and use the Ctrl+Shift+C shortcut to turn on captions. If captions still do not appear, try the web version of Teams at teams.microsoft.com to see if the issue is app-specific.
If Teams Still Has Issues After the Main Fix
Captions Button Is Grayed Out
A grayed-out captions button means your admin has disabled the feature in the meeting policy. You cannot override this setting yourself. Contact your IT administrator and ask them to enable Live captions in the applicable meeting policy.
Captions Show the Wrong Language
If captions appear but in the wrong language, the spoken language does not match the caption language. In the meeting, select the ellipsis button (three dots) and choose Turn on live captions. Then select the gear icon next to captions and change the spoken language to match the meeting. Also verify that the Windows display language matches that language.
Captions Start But Stop After a Few Seconds
This often happens when the meeting audio is poor or the speaker is too quiet. Check that the microphone is not muted and that the speaker volume is above 50%. Also close other applications that might use the microphone, such as voice assistants or recording apps.
New Teams vs Classic Teams Behavior
The new Teams app has the same captions feature but some settings are in different places. If you are using the new Teams, go to Settings > Captions and transcription and ensure the toggle is on. If you recently switched from classic to new Teams, clear the cache for the new Teams app as well by deleting the %appdata%\Microsoft\Teams folder after closing the app.
New Teams Desktop vs Teams on the Web: Key Differences
| Item | New Teams Desktop (Windows 11) | Teams on the Web |
|---|---|---|
| Live captions availability | Full support with toggle in settings | Support depends on browser and meeting policy |
| Cache reset | Delete %appdata%\Microsoft\Teams | Clear browser cache and site data |
| Language pack dependency | Uses Windows language settings | Uses browser language settings |
| Keyboard shortcut Ctrl+Shift+C | Works in desktop app | Works only when browser focus is on the meeting |
| Admin policy override | Applies to both, but desktop may sync faster | Applies, but policy changes may take longer to reflect |
After applying the fixes, you should be able to turn on live captions in any meeting. Start with the policy check because that is the most common blocker. Then update your language settings and clear the cache if needed.
For a quick test, join a meeting with yourself and press Ctrl+Shift+C. If captions appear, your setup is correct. If not, revisit the language pack installation because that is the second most common cause.
As an advanced step, you can also set the default caption language in your Teams settings so you do not have to change it for every meeting. This works best when your meetings are always in one language.
