How to Add ASR (Automatic Speech Recognition) Captions to a Video

 Overview
Creators can add Automatic Speech Recognition (ASR) generated captions to their Panopto videos. In this article, learn how to add and edit ASR captioning.  

Note: Machine-generated captions are not the same as human transcriptions; as such, reviewing and editing ASR captions for accuracy is recommended. If multi-language ASR captioning is enabled, captions can only be added for the site or folder's default language.  If you need to reprocess captions, please contact Panopto Support.
