Add subtitles or captions to your Microsoft Stream video

You can add subtitles or captions to any Microsoft Stream video during upload or after. You can also choose to configure your video so Stream generates captions automatically using Automatic Speech Recognition technology. For more information, see Autogenerate captions.

Captions are indexed and used by Stream to power deep search, helping viewers watch exactly what they need. For information about how to use deep search, see Search words spoken in a video.
