What is Live Caption on Chrome?
Introduction
Live caption is a feature that allows users to watch videos with real-time captions in real-time. It is a powerful tool that can be used to improve accessibility, enhance the viewing experience, and provide valuable information to users with hearing impairments. In this article, we will explore what live caption is on Chrome, its benefits, and how to enable it.
What is Live Caption?
Live caption is a feature that uses the WebRTC (Web Real-Time Communication) protocol to transmit real-time captions to the user’s device. It is a combination of the WebRTC API and the Google Chrome browser’s built-in captioning capabilities. The live caption feature is designed to provide a seamless and accurate captioning experience, allowing users to watch videos with real-time captions.
How Does Live Caption Work?
The live caption feature works by using the WebRTC API to establish a real-time communication channel between the user’s device and the video source. The video source sends the video stream to the user’s device, which then uses the WebRTC API to receive the captioning data. The captioning data is then displayed on the user’s device, allowing them to watch the video with real-time captions.

// Set up the WebRTC API
webRTC.onaddstream = (event) => {
// Add the stream to the captioning data
captioningData.stream = event.stream;
// Set the captioning data
captioningData.sink = event.stream;
// Send the captioning data to the user's device
