In PowerPoint for Windows, macOS, and web, you can add closed captions or subtitles to videos and audio files in your presentations. Adding closed captions makes your presentation accessible to a larger audience, including people with hearing disabilities and those who speak languages other than the one in your video.
Beginning with version 2016, PowerPoint has a new, simpler format for caption files, called WebVTT. The video player in the following versions of PowerPoint can show those captions when you play the video:
The 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. To search online for available tools and detailed instructions, type "create vtt file" in your search engine.
For instructions on showing captions when watching a video in these versions of PowerPoint, see Accessibility features in video and audio playback on PowerPoint.
In Office 2016, the availability of the closed-captioning feature depends on the way Microsoft 365 was installed.

Read the next section to see whether the feature is available to your installation of PowerPoint 2016.
