How to Use Live Caption
Live Caption is installed automatically, but whether or not it’s currently usable depends on whether it’s enabled. Once you’ve turned on Live Caption, there are a few modifications you can make to it depending on your needs.
How to Enable Live Caption
There are two ways to activate Live Caption. You can do this before any audio is playing or you can wait until you need captions to turn it on.
The first and far easier method is to select volume up or down and then tap Live Caption. Depending on how your screen is oriented, it will show up beside (as it does in the screenshot below) or under the volume controls.
If you don’t see Live Caption, the other way to turn it on is through Settings > Accessibility > Live Caption. Tap Use Live Caption (or Live Caption if you see that instead) to turn it on.
The Live Caption screen will show up automatically to display the video captions, podcast captions, etc.
You can quickly disable Live Caption by swiping the caption box off the bottom of the screen. Otherwise, just reverse the steps from above: use the volume menu or toggle it off in settings.
How to Change Live Caption Settings
There are a few settings you can change to control how Live Caption works.
To adjust how much text you can see in the caption area, just double-tap the box. If Live Caption is hiding something on the screen, press-and-hold the box and drag it up or down out of the way.
To hide Live Caption from the volume control menu, or to caption calls, or toggle other settings like profanity visibility and sound labels, go to Settings > Accessibility > Live Caption.
On the Accessibility page is a Caption preferences option where you can change the text size and caption style.
More Information on Live Caption
Live Caption requires extra power to continuously create video captions and transcribe other audio. Having it enabled all the time will drain your phone’s battery faster, so be mindful of how often you use it.
English is currently the only supported language, but Google plans to broaden Live Caption to include other languages in the future.
Live Caption doesn’t support music, so you can’t use it to find song lyrics. There are also some cases where live captions aren’t available because the media provider doesn’t share the audio with Android.
While Live Caption still works even if your phone’s audio is muted, it does require volume from the original audio source. In other words: Live Caption doesn’t read lips!
