Live Caption, Google’s automatic captioning system first introduced at its I/O developer conference this May, is now officially available, alongside the launch of the new Pixel 4. But unlike some of the other technologies highlighted at the company’s Pixel hardware event yesterday, Live Caption won’t be limited to Google’s new smartphone alone. After the initial debut on Pixel 4, the automatic captioning technology will roll out to Pixel 3, Pixel 3 XL, Pixel 3a and Pixel 3a XL before the year-end, says Google, and will become more broadly available in 2020.

The company has already offered automatic captions on YouTube for a decade, but that same sort of experience isn’t available across the wider web and mobile devices. For example, Google explains, you can’t read captions for things like the audio messages sent by your friends, on trending videos published elsewhere on social media, and on the content you record yourself.
