Live CaptionSome examples of Android camptioning, an automatic captioning system that is fast and small enough to fit on a smartphone. Live Caption is helpful whether you’re on a loud commuter train, trying not to wake a baby, or want to follow along the conversation more closely. 

With the launch of Pixel 4, Live Caption is now officially available to make digital media more accessible. With a single tap, Live Caption automatically captions videos and spoken audio on your device (except phone and video calls). It happens in real time and completely on-device, so it works even if you don’t have cell data or Wi-Fi, and the captions always stay private and never leave your phone. The captions won’t get in the way of whatever you’re looking at because you can position them anywhere on the screen. If you want to see more text, simply double tap to expand the caption box.
