role="doc-cover"

[RajeshVimal]

If we use role="doc-cover" in the tag, JAWS ignores the alt description provided for the image, but NVDA reads.

@RajeshVimal may I ask in which tag? Image HTML tag img?

[RajeshVimal]

Yes.
<img role="doc-cover" src="cover.jpg" alt="cover image"/>

I am surprised that JAWS would ignore the alt text just because there was role="doc-cover" since doc-cover is a child of superclass img which JAWS should be handling normally for all images I would imagine.

Did you try removing just the role and see if JAWS then reads it? Sounds like a JAWS bug to me if that is the case.

BTW alt="cover image" isn't considered good alt text but I am sure you just put that in for explanation.

Here is exactly what comes from the ARIA module.

EXAMPLE 13
<img role="doc-cover" src="coverimage.jpg" alt="A Room of One's Own by Virginia Woolf"/>

It could be an issue with the reading system perhaps? May want to try just looking at the xhtml of the coverage in a browser and see how JAWS handles that page.

I just removed and verified in JAWS. It reads alt description. For confidentiality reason, i used the placeholder text in alt.

I used the below combination to test the epub file.

Vital source bookshelf (desktop version) + JAWS + Windows 10 platform

@RajeshVimal Understood about the title text ;)
I would be curious to hear the results of that cover.xhtml page read with jaws in Edge to see if you get the same results.
Sounds like a bug needs to be filed against JAWS.

It seems to be problem with ereader application, i just read the cover page alone in Chrome through JAWS, it reads the images description. In Edge, it not reads the cover image neither with role attribute nor without role attribute.

This issue has been inactive for a while and doesn't look like an issue with EPUBCheck itself. Closing.
