Pixel's new Live Caption feature automatically adds captions to video and spoken audio on your device outside of phone or video call apps.
Google has launched an automatic voice captioning technology for its latest Pixel hardware. Available immediately with the launch of Pixel 4 and before the end of 2019 for Pixel, Pixel 3XL, Pixel 3a, and Pixel 3a XL, Live Caption stores all caption data on your device securely and without the need for a Wi-Fi or cell signal to function.
