I tested one screen reader (JAWS) combined with Internet Explorer.
The document is read interactively. There's a key to read the next or
previous paragraph, keys to jump to a section defined by a header
level.
There's a heading navigation dialog box to see the structure of the
document and jump to a specific place.

This wouldn't be equivalent to a screen reader such as JAWS.
However, it may be possible to extract the data of a HTML document,
deleting navigation bars and decorative things. I don't have a
specific algorithm to recognize these things.
Moreover tables and divisions will be difficult to interpret.
