I just tried that. When setting an "Alt Text" in Word, that is shown as 
"Description" in the "Properties" -> "Options" for the image after 
opening the document in Writer, and (as can be seen in Accerciser) it's 
used as the accessible description, too. There's also a "Text 
Alternative" that can be set in Writer, which is used as the accessible 
name, if set. (Word doesn't seem to distinguish between the two at all.)

So the import from OOXML seems to work fine.

I can reproduce that Orca doesn't announce an image when announcing a 
line containing an image anchored as character, even if both of the 
above attributes are set.

There is this existing bug report which sounds like it describes the 
same issue:
https://bugs.documentfoundation.org/show_bug.cgi?id=77679
("[ACCESSIBILITY] Accessibility support for replaced objects is incomplete")

Orca does however announce the accessible *name* (not the description by 
default, at least in my setup) when using the "To Next Frame" shortcut 
Shift+F4 to select the image.
