As an audiologist, I often see patients who tell me: “Even with my hearing aids, I sometimes miss words during online meetings, lectures, or videos.” That’s where live captioning technology can be a game-changer.
For individuals with hearing loss, captions provide visual reinforcement of speech, reduce listening fatigue, and make digital communication more inclusive. The great news? You don’t have to wait for every website or video platform to provide captions—you can add them yourself with Chrome extensions.
In this article, I’ll walk you through the best Chrome extensions for live captioning that I recommend to my patients and anyone looking to improve their communication access online.
Why Live Captioning Matters
Even with advanced hearing aids or cochlear implants, certain situations remain challenging:
- Fast speakers or accents can distort clarity.
- Background noise often masks important speech sounds.
- Online content without captions leaves gaps in understanding.
Live captioning fills these gaps by turning speech into readable text instantly.

1. Google Chrome’s Built-In Live Caption
Best for: Everyday browsing, YouTube, and podcasts
Google has integrated its own Live Caption feature directly into Chrome. Once enabled in the browser’s settings, captions appear automatically for audio and video content—even if the site doesn’t provide them.
Pros:
- Works offline and online.
- Captions virtually any audio/video.
- Customizable font size and style.
Cons:
- English-only (for now).
- Not always perfect with accents.
How to Enable:
Go to Settings > Accessibility > Live Caption in Chrome and toggle it on.

2. Web Captioner
Best for: Meetings, lectures, and live presentations
Web Captioner is a free, browser-based captioning service that uses Chrome and your device microphone to transcribe speech in real time.
Pros:
- Over 40 languages supported.
- Adjustable caption window for visibility.
- Great for classrooms, churches, and public talks.
Cons:
- Requires internet connection.
- Works best on a computer, not mobile.
Audiologist tip: I often recommend Web Captioner for patients who attend online classes or town hall meetings that lack captions.

3. Otter.ai Chrome Extension
Best for: Business meetings and note-taking
Otter.ai is a leading transcription service with a Chrome extension that captions live conversations in Zoom, Google Meet, and Microsoft Teams.

This is an excellent choice if you want both live captions and meeting notes afterward.

Final Thoughts from an Audiologist
Captions are not just a convenience—they’re a lifeline for communication. Whether you’re watching Netflix, attending a Zoom meeting, or listening to a podcast, Chrome extensions can help ensure you never miss a word.
If you wear hearing aids, combining amplification with visual captions can dramatically reduce fatigue and increase confidence in conversations.
