Difference between audiobook, media overlays and tts

I see it was requested in the a11y task force call on 2021-02-11 that I add a note to the optimized publication section explaining the differences between these concepts, but such a discussion doesn't appear germane to the section. Audiobooks aren't in scope of the specification, TTS is not an optimization, and full audio only falls into the category when it's not included with full text, as already explained.

I'd suggest putting a general explanation in the techniques document section on primary access modes instead. I think this discussion is helpful in terms of explaining when a primary mode of auditory should be specified (even if audiobooks don't fit the discussion, they could be mentioned in comparison).

The other options I can think of include:

  • adding a description of the difference between media overlays and a pure audiobook to the media overlays section of the core specification (not sure TTS fits here)
  • writing a separate informative note that explains the differences between the three to avoid shoehorning this into sections where it doesn't fully fit

We might even want to consider a mix of these (e.g. descriptions in the techniques and media overlays).

Thanks @mattgarrish let's discuss about this in this week PCG meeting?

Looks like github has bunged up the transfer of this issue (maybe the rest will show up one day), but where this ended is that it's not a document that would be specific to EPUB so not a fit to publish in the WG.

We're assuming the accessibility task force will produce the document, and we can look at where it might be referenced from EPUB/Audiobooks after. I'll leave it to @avneeshsingh on how best to get to work on this, though.

This issue came from Accessibility task force of EPUB 3 WG, when we were discussing Media Overlays and AccessModeSufficient metadata for different kind of Ebooks. As @mattgarrish mentioned, this is not specific to EPUB format, so we decided that we should not work on this document in EPUB 3 WG, and we should take it forward in a group which is not focused on one specific publishing format, i.e. Publishing CG

@geoffjukes, I will be glad to discuss it further in CG.

For reference, here is the original issue which has reappeared back in the epub-specs repository: https://github.com/w3c/epub-specs/issues/1514
