I dont see why the speech tools should be handled in any way different
from the other acessibility tools we ship: in that they are part of
the session. While I am no accessibility expert I am kinda sure that
on Fedora all accessibility stuff is run inside the user session and
the gdm pseudo-session so that the fully a11y features are available
both before and after the login.
