About
Microsoft Live Captions is a built-in Windows 11 accessibility feature that provides real-time on-device transcriptions of any audio playing on or through a PC—including system audio, app output, and microphone input—without sending audio data to Microsoft servers.
What It Does
Live Captions generates a movable, dockable caption bar that works across all apps, from streaming video and online meetings to in-person conversations captured through the microphone. Processing happens entirely on-device using a local AI model, so captions work offline and conversations remain private.
Who It Helps
Microsoft Live Captions is available at no additional cost to Windows 11 users who are deaf or hard of hearing, and is also valuable for people in noisy environments, non-native speakers, and anyone who benefits from reading alongside listening.
