After making the Live Caption feature available in its Pixel Phones on Android, Google is now bringing it to Chome browser on Windows, Mac, Linux, and Chrome OS platforms. What this means is Chrome will automatically detect speech in media and generate captions for all media playing in the browser if users enable ‘Live caption’ switch in accessibility settings.
Accessibility wise, Google Chrome for screen reader users already allows generating descriptions for the images that don’t have alt text, and the Chrome browser also links to Windows 10 Captions from its Accessibility Settings to allow users to customize the way closed captions appear in the browser.

1. Launch latest Chrome Canary 84.0.4136.2 or later
