Read Any Windows Audio as Captions
Windows 11 Live Captions turns spoken audio from videos, meetings, and nearby conversations into on-screen text: free forever with no card on Windows 11 version 22H2 or later, but Microsoft publishes no usage quota or reset schedule.
This is not a claim that Live Captions replaces a $139 subscription. It is included at no extra charge when you already have a compatible Windows 11 PC. A new Windows 11 Home license is listed by Microsoft at $139.
Will you hit a free limit?
Microsoft does not publish a numeric usage allowance, a daily or monthly cap, or a reset cadence for Windows 11 Live Captions. Because the feature processes captions on-device, this guide cannot honestly calculate a usage limit.

Set it up before you need it
Start Live Captions
Press Windows + Ctrl + L. The first run may ask you to consent to on-device voice processing and download speech-recognition language files. Finish that setup before depending on it for a meeting, class, or appointment.
If the shortcut does nothing, go to Start → All apps → Accessibility → Live captions, or open Settings → Accessibility → Captions.
Choose the right audio source
For a meeting, video, podcast, or browser tab, leave microphone audio off. Live Captions reads audio passing through the PC.
For an in-person conversation, open the caption window’s Settings menu, choose Preferences, then enable Include microphone audio. System audio has priority if both are active, so it may not transcribe both sides of an overlapping call cleanly.
Put the text where it helps
Use the caption window’s Settings → Position menu. Pick Above screen for meetings or shared screens, Below screen for many videos, or Floating on screen when you need to move it around content.
Use Preferences → Caption style to choose a style that is easier to read. Make the window taller if you need more visible lines.
Save a repeatable setup note
Copy this into Notes, OneNote, or a calendar reminder before an important conversation.
Live Captions setup: 1. Press Windows + Ctrl + L. 2. Confirm captions appear before the speaker begins. 3. Use system audio for calls and videos. 4. Turn on microphone audio only for in-person speech. 5. Put captions above screen if they cover shared content. 6. If captions lag, close unused apps and remove video background effects.
Run a low-stakes test
Play 30 seconds of spoken video, press Windows + Ctrl + L, and move the window. If captions lag or drop, close unused programs and reduce video effects. This test catches setup problems before a conversation where you need the text.
Captioning is support, not a record
Live Captions recognizes speech, not every sound. Music, applause, and other audible events are not captioned; sung lyrics are not reliably captioned. Fast speech, technical terms, background noise, and speakers talking over each other can produce mistakes.
Resource-intensive apps can cause delayed or dropped captions. For high-risk or emergency information, confirm important details with the speaker or another trusted source. The tier-specific limit is hardware and software: you need Windows 11 version 22H2 or later; translation has separate Copilot+ PC requirements.
Small choices that make it useful
Caption 30 seconds of spoken audio
Play a short video with speech, press Windows + Ctrl + L, and move the captions box to the top of your screen. If it works, keep the setup note ready for the next call, appointment, or training video.
