Just in case you would like to test this: there are two free options 
on Windows:

* NVDA: an open-source screen reader: <http://www.nvda-project.org/>. 
(The portable version can be run from a USB key if you don't want to 
install it.) When testing with a screen reader, you first need to 
installe the Java Access Bridge: 
<http://www.oracle.com/technetwork/java/javase/tech/index-jsp-136191.html>.

* The Java Accessibility Utilities, which you can (still) find at 
<<http://java.sun.com/javase/technologies/accessibility/downloads.jsp>http://java.sun.com/javase/technologies/accessibility/downloads.jsp>. 
Because LibreOffice on Windows uses the Java Accessibility API, you 
can these inspection tools.
The Java Accessibility Utilities include Java Monitor, Ferret, Monkey 
and AccessibilityMonitor. To use, for example, Java Monitor, one 
should go through the following steps:
1. Add the jar files jaccess.jar and jaccess-examples.jar in the CLASSPATH.
2. Modify the file lib/accessibility.properties in the JDKHOME 
directory to include the following line:
assistive_technologies=JavaMonitor
Note that the README.txt claims that this line should be 
"AWT.assistive_technologies=JavaMonitor", but this is not correct.
3. When you start LibreOffice (or a pure Java application), Java 
Monitor will start automatically.
For checking accessible name, description, role, value and state(s) 
in menus, Ferret is the appropriate tool.
(Oh, and alway close LibreOffice if you want to close the 
accessibility utility; if you try to close the accessibility utility 
first, it will also close LibreOffice.)

OK. And thanks for asking questions about accessibility :-)

Best regards,
