Dictionary for automatic captions at the folder (or session) level, made up from session files

We use Panopto for university lectures and educational video, in Spanish. A lot of technical / scientific terms appear in every session recorded. ASR does very poorly when trying to recognize these "uncommon" words, and therefore it becomes useless (although often very funny). Because of inaccuracy in ASR, our instructors / videographers are not using ASR at all. This is a big problem for hearing-impaired students, who need captions. Other caption options are either not available or too cumbersome to use at our scale.

However, I understand that Panopto allows for a site-wide custom dictionary to help in ASR accuracy. In a university, a site-wide dictionary would be too large and cumbersome to maintain; but maybe such a dictionary could be set up at folder level, or even at session level. That dictionary could be built up automatically from the files attached to the session, or from the Powerpoint slides text which is already used for smart chapters. Instructors could upload a text or PDF for each folder or session, and maybe "uncommon" words could be extracted by some AI text tool, to fill the dictionary.

This feature would be a game changer for hearing-impaired student access, but also for other use cases, such as using ASR combined with AI text tools to summarize a class discussion.

    +1 Building a dictionary from slides and pdfs is a great idea! The video channels are already processed by AI to pick out slide/chapter headings, so perhaps this could feed into it as well?
