This article is for people who use a screen reader program such as Windows Narrator, JAWS, or NVDA with Microsoft 365 products. This article is part of the Microsoft 365 screen reader support content set where you can find more accessibility information on our apps. For general help, visit Microsoft Support.
Use PowerPoint with your keyboard and a screen reader to add closed captions to videos. We have tested it with Narrator, JAWS, and NVDA, but it might work with other screen readers as long as they follow common accessibility standards and techniques. With closed captions, you can open up your presentation to a larger audience, for example, people with hearing disabilities or those who speak languages other than the one in your video.
The video player in PowerPoint shows the captions when you play the video. For instructions, refer to the section "Turn on closed captions or subtitles by using the keyboard" in Accessibility features in video and audio playback on PowerPoint.
Closed captions are stored in a text-based file with a .vtt filename extension. You can create a closed caption file on your own or use a caption creation tool. For more info, refer to Create closed captions for a video. To search online for available tools and detailed instructions, type "create vtt file" in your search engine.
To learn which caption file types are supported, refer to Closed Caption file types supported by PowerPoint.
Notes:
-
New Microsoft 365 features are released gradually to Microsoft 365 subscribers, so your app might not have these features yet. To learn how you can get new features faster, join the Office Insider program.
