If you are watching a video tutorial recorded in a busy environment, or listening to a podcast where the host is mumbling, it can be incredibly difficult to understand the audio. While major platforms like YouTube have built-in closed captioning, millions of independent blogs, smaller video players, and audio-only websites do not.
To solve this, Google integrated a powerful accessibility feature called “Live Caption” directly into the Chrome browser. When enabled, Chrome uses on-device machine learning to actively listen to any audio playing through the browser and instantly generates real-time, highly accurate subtitles in a floating box at the bottom of your screen.
How to Enable Live Caption in Chrome
Because Live Caption relies on local speech recognition files, the browser will need to briefly download a small language pack the very first time you turn it on.
- Open Google Chrome on your desktop or laptop.
- Click the three-dot menu icon in the extreme top-right corner of the window.
- Select Settings from the drop-down menu.
- In the left-hand navigation pane, click on Accessibility.
- Locate the toggle switch labeled Live Caption (the subtext explains it automatically creates captions for English media).
- Toggle the switch to the On position.
You will briefly see a “Downloading speech recognition files” progress bar beneath the toggle. Once it finishes, the feature is ready to use.
How to Use the Caption Box
You do not need to manually trigger the captions for every video.
Simply navigate to a webpage containing audio (such as an embedded Twitter video, a Spotify web player track, or a random news clip) and press play. Within two seconds, a sleek, translucent black box will appear at the bottom-center of your Chrome window, displaying the generated text exactly in sync with the spoken words.
- Moving the Box: If the caption box is blocking an important part of the video, you can click and drag it anywhere else on your screen.
- Expanding the Box: By default, it shows two lines of text. Click the small arrow icon at the bottom of the box to expand it into a much larger square that displays several sentences of history.
- Closing the Box: If you no longer need subtitles for a specific video, simply click the X in the top-right corner of the caption box. The box will vanish and will not reappear until you navigate to a completely different webpage or manually restart your browser.
