Narrated Slide Shows: Possible Destinations?

[iwelch]

I am trying to figure out whether it is possible to create a narrated slide show in pandoc.

I believe most browsers and pdf viewers have by now clamped down on narrations (not allowing autoplay) due to ad abuse, so only Google ("Slides"), Microsoft ("Powerpoint"), and LibreOffice ("Impress") even still have this feature. The old rich media aspects of the web and pdf have become very user-unfriendly, such as requiring clicking on each and every page.

Has anyone tried to create a narrated slideshow in pandoc with appropriate audio file(s)? I would of course have to be able to link different audio files to particular slides. (I am thinking about "reverse-engineering" how Impress stores its audio files and code this as a post-pandoc transformer...)
