Windows 11 Live Captions: Turn On Subtitles for Any Audio

Live Captions is an accessibility feature in Windows 11 that listens to the sound coming from your PC and turns it into on-screen text in real time. Unlike the closed captions built into a video player, Live Captions works across the whole system: a YouTube clip, a Teams meeting, a podcast, a voice message, or even your own microphone input all get subtitles.

The captions are generated on your device, so the audio does not have to leave your computer. This guide shows how to switch Live Captions on, move the caption bar, style the text, include your microphone, and resolve the problems people hit most often.

What Live Captions Can Do

Live Captions appeared in Windows 11 version 22H2 as a built-in alternative to third-party transcription tools. It converts speech to text locally, which means the processing happens on your PC rather than on a remote server. That keeps your conversations private and means the feature works offline after the language model has been downloaded.

Typical uses include:

Following a video or podcast without sound, for example in a quiet office or library
Reading what is said during a video call when the audio is unclear or you are hard of hearing
Transcribing a meeting in real time so you can concentrate on the discussion instead of taking notes
Captioning your own voice so an audience can read what you are saying during a presentation

Live Captions works with any app that plays audio through Windows, because it taps into the system audio stream rather than relying on individual apps to support it.

Turn On Live Captions

There are two quick ways to start Live Captions, plus a deeper settings route for first-time setup.

Method 1: Keyboard shortcut

Step 1. Press Windows logo key + Ctrl + L. This is the universal shortcut and works from anywhere, including full-screen apps.

Step 2. The first time you use it, Windows downloads the speech model for your language. Wait for the download to finish; the caption bar appears at the top of the screen automatically.

Method 2: Quick settings

Step 1. Click the network, sound, or battery icon in the taskbar to open quick settings.

Step 2. Click the Accessibility tile (the person icon), then turn on Live captions.

Method 3: Settings

Step 1. Open Settings > Accessibility > Captions.

Step 2. Turn on the Live captions toggle at the top of the page.

Step 3. If you want it to start every time you sign in, turn on Start live captions when I sign in.

Note: The first download can be several hundred megabytes, so it is worth doing it on a Wi-Fi connection rather than a metered mobile hotspot.

Move and Resize the Caption Bar

The caption bar is a floating window that you can position anywhere on screen. By default it sits at the top, but you can dock it to the bottom or let it float.

Step 1. Hover over the caption bar. A small toolbar appears on the right.

Step 2. Click the Position icon and choose Top, Bottom, or Floating. Floating mode lets you drag the bar anywhere, which is useful if a video player has controls at the top or bottom.

Step 3. To resize the bar, drag its edges in floating mode, or use the height handles in docked mode.

Step 4. Click the Settings (gear) icon on the caption bar itself for quick access to caption style and language without opening the full Settings app.

Change the Caption Style

Windows lets you adjust the text size, colour, background, and font so the captions are readable against any video background.

Step 1. Open Settings > Accessibility > Captions.

Step 2. Under Caption style, pick one of the built-in presets: Default, Small caps, Large text, or Yellow on black. Each preset shows a preview above the list.

Step 3. Click Edit to create a custom style. You can change the text colour, transparency, size, font family, background colour, and window colour.

Step 4. Save the style. It applies immediately to the live caption bar and is used every time you start the feature.

If you are presenting on a projector, a high-contrast style such as yellow text on a black background is usually the easiest for an audience to read.

Caption Your Microphone and Meetings

By default Live Captions only captions the audio playing through your speakers or headphones. To include what you say into a microphone, you need to switch the audio source.

Step 1. Click the Settings icon on the live caption bar.

Step 2. Under Caption options, tick Include microphone audio. This adds your microphone input to the captions alongside the system audio.

Step 3. If you are in a meeting, this lets you read both the other participants (system audio) and your own voice in one caption stream.

Step 4. To caption only your microphone, for example during a live presentation, mute the system audio in your meeting app and keep microphone audio ticked in the caption settings.

For best accuracy, speak clearly and use a headset microphone rather than the laptop's built-in mic, which can pick up fan noise and keyboard clicks.

Fix Common Problems

Live Captions is reliable, but a few issues come up regularly.

The shortcut Win + Ctrl + L does nothing.

Step 1. Check that your Windows version supports it. Live Captions needs Windows 11 22H2 or later. Go to Settings > System > About to confirm your version.

Step 2. Open Settings > Accessibility > Captions and turn the toggle on manually. If it works from there, the shortcut may be blocked by another app; restart the PC and try again.

Captions are missing or delayed.

Step 1. Wait a few seconds. Live Captions needs a short buffer before it starts displaying text, and a weak CPU can lengthen the delay.

Step 2. Make sure the audio is actually playing through Windows. Some professional audio apps route sound outside the default stream, which Live Captions cannot reach.

Step 3. Restart the feature by turning the toggle off and on again.

Accuracy is poor.

Step 1. Check the selected language. Live Captions works best when the speech matches the downloaded language model. You can add more languages in Settings > Time & language > Language & region.

Step 2. Reduce background noise and use a clearer microphone for your own voice.

Captions cover the video subtitles.

Step 1. Move the caption bar to the opposite edge, or use floating mode and place it in a corner of the screen where it does not overlap the content.

FAQs About Windows 11 Live Captions

Does Live Captions work offline?

Yes, after the initial language model download. The speech recognition runs on your device, so no internet connection is needed while captioning.

Can Live Captions translate into another language?

No. Live Captions transcribes speech into the same language it is spoken in. For translation, use a dedicated app such as the Translator app or a browser-based translation tool.

Why is there no sound when Live Captions is on?

Live Captions does not mute your audio. If sound disappears, check that the volume is up and that the correct output device is selected in quick settings.

Can I save the captions as a transcript?

The built-in feature does not save a transcript file directly. You can select and copy text from the caption bar while it is visible, or use a separate transcription tool if you need a permanent record.

Does Live Captions use a lot of battery?

It uses some CPU power for the on-device speech recognition. On a laptop you may notice a small increase in battery drain during long sessions, but it is generally lighter than streaming a video.

Back Up Windows Before You Change Settings

Live Captions is straightforward to enable, but if you are also adjusting audio devices, display scaling, or accessibility options, a system backup gives you a safe rollback point. Qiling Disk Master creates a full image of Windows in a few clicks.

Part 1: Create a Full System Backup

Step 1. Install and open Qiling Disk Master. On the home screen, open "Backup and Recovery" and choose "System Backup". This option automatically includes Windows and the hidden boot partitions, so you do not have to select them one by one.

Step 2. Check the source. The disk where Windows is installed and its system partitions are already ticked for you. If you only need your personal documents, run a separate "File Backup" task instead.

Step 3. Click the destination box and choose where the image should be saved. Use an external HDD or SSD, a NAS, or any drive other than the one Windows is installed on, and make sure it has enough free space.

select an external drive as the system backup destination

Step 4. Review the task summary and click "Proceed". Wait until the progress bar reaches 100%. Do not unplug the drive or turn off the PC while the backup is running.

click Proceed to start the system backup

Part 2: Restore Windows from the Backup

Step 1. Open Qiling Disk Master again, go to "Backup and Recovery", and select the recovery option. Your backup images are listed, so pick the one you created before the changes began.

Step 2. Choose the target disk or partition. Normally you restore to the original system disk. If the drive was replaced, select the new disk instead, and the restore rebuilds Windows together with its boot partitions.

choose the target disk for the system restore

Step 3. Preview the restore plan, click "Proceed", and confirm the warning. The PC restarts to finish the job, and Windows comes back exactly as it was on the day the image was created, with your files and programs intact.

Note: Keep the backup image on a separate drive, and refresh it before you change audio devices or accessibility settings that affect how the system sounds and displays.

Conclusion

Live Captions turns any audio on your Windows 11 PC into real-time subtitles, from videos and podcasts to meetings and your own microphone. Press Win + Ctrl + L to start it, move the caption bar to the top, bottom, or a floating position, and style the text to suit your screen. The feature works offline after the first language download, runs on-device for privacy, and only needs a microphone toggle to caption your voice in meetings. If the shortcut does nothing, confirm you are on Windows 11 22H2 or later and turn it on through Settings > Accessibility > Captions instead.
