How to Change Subtitle Settings in Windows 10
Windows 11 just got cooler! The latest version, 22h2, now includes a feature called Live Captions, which can display real-time subtitles for audio and video files. Not only can this help people with hearing loss, but it can also help non-native speakers or people trying to learn a new language. The best part? You can customize the subtitles to your liking and have them appear on any part of the screen. Plus, you don’t need an internet connection to turn Live Captions on or off.
You can use the Live Captions feature to convert audio to text while watching your favorite shows and movies, or while listening to audiobooks or podcasts. This feature isn’t available on older versions of Windows, but don’t worry. Windows 10’s accessibility features include the option to play closed captions at the bottom of the video you’re watching, if the file is available.
There are two ways to enable Live Captions on your Windows 11 device. Whichever way you choose, the end result is the same: Windows will display an automatic transcript for the video or audio you're currently playing.
