Google's Live Caption accessibility feature received the ability to transcribe phone calls with the launch of the Google Pixel 4a earlier this month. At the time, the company had revealed that the new functionality would soon make its way to older Pixel devices with Live Caption support, including the Pixel 2, Pixel 3, Pixel 3a, and Pixel 4. Now, the feature has finally started showing up on some of these devices.

Our Editor-in-Chief Mishaal Rahman has received the feature on his Pixel 4 and, as you can see in the attached screenshots, it can be enabled by tapping on the new 'Caption calls' option within the Live Caption settings. Tapping on the option brings up a pop-up menu which lets you define the behavior of the call transcriptions. You can either choose to leave the feature off, have it on for all calls, or have your phone prompt you for each call.

In response to Mishaal's tweet, a few other Pixel users have confirmed that the feature has also made its way to the Pixel 3 XL and the Pixel 3a. In case you're not familiar with the feature, Live Caption essentially captures audio from your device and runs it through three on-device machine learning models to generate captions from any English-language speech. The feature works with a variety of media and phone calls, including ones made over third-party apps like WhatsApp and Telegram, but it currently only supports English-language speech.

Along with the aforementioned devices, Live Caption in phone calls should also make its way to the Pixel 2 series considering that the devices do offer Live Caption support. It's also likely to roll out to other non-Google devices that offer Live Caption support, like the Samsung Galaxy S20 series, OnePlus 7T series, OnePlus 8 series, and the OnePlus Nord in the near future.
