Summary:
Google Chrome’s Live Caption feature provides automated real-time transcription for multimedia content including videos, podcasts, and video calls, enhancing accessibility for deaf/hard-of-hearing users and non-native speakers. While enabled by default in most installations, manual activation may be required through Chrome’s Accessibility settings across desktop and mobile platforms. Alternative solutions like Windows OS-level captions and third-party extensions like Substital offer fallback options when native implementation fails. This functionality represents a critical advancement in baseline digital accessibility standards for web browsers.
What This Means for You:

- Multilingual Support Strategy: Leverage auto-transcribed captions during international video conferences to improve comprehension accuracy for non-native language speakers
- Content Engagement Boost: Enable captions during mobile video consumption in sound-sensitive environments using Chrome for Android/iOS caption toggle features
- Future-Proofing Advisory: Bookmark Substital extension as contingency for caption generation failures, particularly with DRM-protected streaming content
