How to Turn On Live Caption on a Chromebook

What Live Caption does on ChromeOS

Live Caption is a built-in ChromeOS accessibility tool that listens to audio playing on your Chromebook and converts speech into on-screen text in real time. It works across a wide range of content: streaming video, webinars, podcasts, voice messages, and even your own microphone audio when you are in a call. The captions appear in a floating window at the bottom of the display, so you can follow along without turning up the volume.

The feature is especially useful in loud environments where you cannot hear clearly, in quiet spaces where you want to keep the volume low, or when the person speaking has a heavy accent or speaks softly. It also helps if you have any degree of hearing loss and want to supplement what you hear with a text version.

Because Live Caption runs directly on the Chromebook, it works even when you are using apps or websites that do not provide their own captions. You do not need an internet connection for the base feature, which makes it a reliable companion during offline viewing as well. For international meetings, ChromeOS also supports AI-translated captions on meeting platforms and live streams, which can bridge language gaps in real time.

Live Caption is part of the broader accessibility toolkit in ChromeOS. If you rely on other assistive features, you can manage them all from the same area in Settings, such as high contrast mode and screen magnification.

How to turn on Live Caption

Turning on Live Caption takes only a few taps. The exact labels have stayed consistent across recent ChromeOS versions, so the steps below should match what you see on most Chromebooks in 2026.

Begin by making sure your Chromebook is updated. Live Caption relies on the latest speech recognition models, and Google pushes improvements through routine ChromeOS updates. Your Chromebook checks for updates automatically when it connects to the internet, and you can manually check by going to Settings, then About ChromeOS, and selecting Check for updates. See our guide to checking and installing updates for more.

Once your system is current, follow these steps:

• Click the time in the bottom-right corner to open Quick Settings.
• Select the gear icon to open Settings.
• In the left sidebar, choose Accessibility. If you do not see it, scroll down or search for "Accessibility" in the Settings search bar.
• Under the Audio and captions section, select Captions.
• Toggle Live Caption to the on position. You should see a small caption window appear at the bottom of your screen as soon as the feature is active.
• When you play any media with speech, captions will show up automatically. For calls, Live Caption also captions the other person's speech when your microphone is in use.

Adjusting caption size and style

The default caption style is a small white text on a black background, which works well for most situations. But if you have low vision, watch from across the room, or simply prefer a different look, you can customize the appearance from the same Captions menu in Settings. For more on display adjustments, see our display guide.

In the Captions settings, you will find options for text size, font family, text color, text opacity, background color, background opacity, and window color. A preview box at the top of the menu shows how your changes will look before you apply them.

If you need larger text, slide the text size scale upward. For higher contrast, choose a strong text color like white or yellow on a black background. If you find the box distracting, you can make the background transparent so only the text appears. These settings apply immediately, so you can play a short video and tweak until it feels right.

Using Live Caption for calls and meetings

Live Caption is not limited to video playback. It also captions speech from your microphone during calls and meetings, which means you can read what the other person is saying when you cannot hear them clearly. This is especially helpful in noisy environments or when you are on a hands-free call and the audio is too quiet.

On Chromebook Plus models, the built-in microphones and speakers are tuned for clearer voice pickup and output, and Google's processing adds noise canceling and studio effects to improve call quality. When you combine that hardware with Live Caption, you get a dependable setup for remote meetings, online classes, and video calls with family.

To use Live Caption during calls, simply keep the toggle on. It works with the built-in ChromeOS calling features and with most web-based meeting services that use the browser's audio pipeline. On managed devices, an administrator can disable Live Caption, so if the option is grayed out at work or school, contact your IT admin.

If you need captions in a different language or for a translated conversation, ChromeOS supports AI-translated captions on meeting platforms and live streams. This goes beyond the base Live Caption and is available on devices and accounts that meet the system requirements.

Troubleshooting Live Caption

If Live Caption does not produce captions, check the basics first. Make sure your Chromebook is running a recent version of ChromeOS. Older operating system versions can lack the latest speech models, and in some cases the feature simply is not available on very old platforms. Chromebooks receive updates for 10 years from the platform release date, so a device that is still supported should have access to Live Caption.

If the toggle is on but no captions appear, try restarting your Chromebook. Sometimes the speech recognition service does not initialize properly after a long sleep. Also check that the audio is actually playing through the Chromebook's speakers or a connected headset, because system-wide muting can prevent the caption engine from picking up the speech signal.

For calls specifically, note that Live Caption captions the microphone audio, so if the other person's voice is not being captured clearly, captions will be sparse. Move closer to the microphone or reduce background noise. You can also test the microphone through the Settings > Device > Audio section to confirm it is working.

If captions are still missing, consider whether an admin policy is blocking the feature on a managed device. In that case, contact your administrator. For personal devices, a Powerwash resets all settings, but it also erases local data, so back up your files first.
