Windows 11 features a built-in accessibility tool called Live Captions that performs on-device, real-time speech-to-text transcription for any audio playing across your system. While the default subtitle banner provides functional readability, many users find the standard presentation too small, poorly contrasted, or awkwardly positioned over important software interfaces. Windows 11 includes an extensive styling engine that lets you personalise fonts, text size, transparency, and screen placement.
How Windows 11 Live Captions Operates
Live Captions transcribes incoming microphone speech as well as system media streams (such as video podcasts, YouTube clips, and Teams meetings) entirely on your local machine without sending audio samples to cloud servers. Once activated with Win + Ctrl + L, the caption box floats dynamically on your screen.
Customising the caption box resolves several common issues:
- Visual Accessibility: Users with low vision can scale typography to extra-large formats with high-contrast outlines.
- Multitasking Efficiency: Repositioning the caption banner from the top of the monitor prevents it from obscuring browser tabs and application title bars.
- Colour Calibration: Transparent backgrounds can be adjusted to solid opaque backplates, eliminating background video bleed.
How to Change Live Captions Screen Placement
You can dock or undock the Live Captions banner to prevent it from covering active work:
- Press Win + Ctrl + L to bring up the Live Captions window.
- Click the Settings (Gear) icon located on the right edge of the caption banner.
- Navigate to Position in the flyout menu.
- Choose between three distinct screen arrangements:
- Top: Docks the banner across the entire top edge of your monitor (pushes desktop apps slightly downward).
- Bottom: Docks the banner directly above your Windows taskbar.
- Overlaid on screen: Converts Live Captions into a floating, resizable window that can be dragged to any secondary monitor or corner.
How to Customise Fonts, Colours, and Contrast Styling
Windows 11 allows you to craft bespoke visual themes matching your desktop workflow:
- Open Settings (Win + I) and navigate to Accessibility > Captions.
- Under the Caption style section, you can select from preset themes: White on black, Small caps, Large text, or Yellow on blue.
- To create a custom style, click Edit next to any style profile.
- Configure the Text attributes:
- Font: Choose between clean sans-serif typefaces (e.g., Segoe UI), monospaced fonts, or formal serif lettering.
- Size: Select 100%, 150%, or 200% for enhanced visual comfort.
- Color: Pick bright yellow, white, or cyan for strong visibility against dark media.
- Opacity: Set to 100% for crisp, non-transparent character glyphs.
- Configure the Background attributes:
- Color: Set to jet black (
#000000) for maximum contrast. - Opacity: Adjust the slider to 100% to completely block bright video backgrounds.
- Color: Set to jet black (
