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.

  • You can't upload a caption file if you have selected to autogenerate captions.

  • You can't autogenerate captions if you have already uploaded a caption file.

If you need to make changes to the autogenerated transcript / caption, you can download the caption file and edit it in a text editor of choice before uploading it back to Stream, or you can edit the transcript directly in Microsoft Stream in the transcript window.

Get just the text from a transcript At times, you may want to get a copy of a video's transcript without any time codes, metadata, and extra lines.

Microsoft Stream doesn't have a built-in way to do this, but you can download the transcript (as listed above) and use a simple web utility to extract the transcript text from your downloaded VTT file. This web utility allows you to pick VTT files from your computer and get a copy of the text portion of the VTT file containing just the transcript.
