Presumably a non-visual UA could use the irrelevant attribute to distinguish
content that was not relevant at the current time from content that was merely
being hidden from graphical UAs. I seem to remember (but I am far from being an
expert) that currently aural browsers ignore display:none content and so
best-practice for adding additional text for aural UAs is to use CSS positioning
to move it out of the viewport. @irrelevant seems to provide a way to move away
from this kind of crazy hack.
