What are Windows 11 Live Captions?
Windows 11 includes a powerful accessibility feature called Live Captions. Unlike the closed captions built into YouTube or Netflix, this tool operates at the operating system level. It intercepts any audio playing through your PC—whether it is a Zoom meeting, a poorly mixed podcast, a video file playing in VLC, or even a live stream on Twitch—and generates real-time, highly accurate text captions on your screen.
Because the transcription model is downloaded locally to your hard drive, Live Captions works completely offline and does not send your audio data to the cloud, ensuring total privacy.
How to Enable Live Captions
The fastest way to toggle the feature is using a global keyboard shortcut.
- Press Windows Key + Ctrl + L.
- The first time you use the feature, a prompt will appear asking you to download the speech recognition language files. Click Download.
- Once the download (usually around 100MB) completes, a dark caption bar will appear on your screen, and it will immediately begin transcribing any spoken audio.
Alternatively, you can enable it through the Settings menu by navigating to Settings > Accessibility > Captions and toggling the Live captions switch to ON.
How to Customize the Caption Window
By default, the caption box anchors itself to the very top edge of your monitor. Depending on your workflow, this might block browser tabs or application menus. You can easily adjust its position.
Click the Settings gear icon located in the top-right corner of the Live Captions window, then hover over Position. You have three choices:
- Top: Docks the bar permanently to the top of the screen, pushing all maximized windows down so they are not obscured.
- Bottom: Docks the bar permanently above your Windows Taskbar.
- Floating on screen: Turns the caption bar into a standard, draggable window. You can resize it, make it transparent, and place it anywhere on your desktop—ideal for placing it directly below a video call.
How to Include Microphone Audio
By default, Live Captions only transcribes system audio (what you hear through your speakers). However, if you are participating in an online meeting or recording a tutorial, you may want it to transcribe your own voice as well.
- Click the Settings gear icon on the caption bar.
- Hover over Preferences.
- Check the box next to Include microphone audio.
Now, the tool will simultaneously transcribe both the remote participants and your local microphone input, providing a complete transcript of the conversation on screen.
How to Change the Appearance of the Text
If the default white text on a black background is difficult to read, you can customize the styling to meet your visual needs.
- Click the Settings gear icon on the caption bar.
- Hover over Preferences and click Caption style.
- This will open the Windows Settings app. Here, you can choose from preset themes (like Yellow on Blue or Large Text), or click Edit to manually change the font family, text size, text color, and background opacity.
Whether you are hard of hearing, working in a noisy environment without headphones, or trying to understand a speaker with a heavy accent, Windows 11 Live Captions is an indispensable built-in utility.
