Orca puts a menu item in Applications->Other. The entry behaves oddly, it seems to do two things at once, start orca, and present the preferences dialog. Clicking it multiple times does not work as expected, and there is no obvious way to stop orca again.
Furthermore, turning off speech does not seem to turn of speech.
i get this, when i start orca from command line (orca-1.0.0-1.fc6.i386.rpm): Traceback (most recent call last): File "/usr/lib/python2.4/site-packages/orca/speech.py", line 57, in getSpeechServerFactories ['']) File "/usr/lib/python2.4/site-packages/orca/gnomespeechfactory.py", line 50, in ? atspi.ORBit.load_typelib('GNOME_Speech') RuntimeError: could not load typelib Traceback (most recent call last): File "/usr/lib/python2.4/site-packages/orca/speech.py", line 98, in init ['']) File "/usr/lib/python2.4/site-packages/orca/gnomespeechfactory.py", line 50, in ? atspi.ORBit.load_typelib('GNOME_Speech') RuntimeError: could not load typelib Traceback (most recent call last): File "/usr/lib/python2.4/site-packages/orca/orca.py", line 882, in _showPreferencesConsole module.showPreferencesUI() File "/usr/lib/python2.4/site-packages/orca/orca_console_prefs.py", line 296, in showPreferencesUI if not setupSpeech(prefsDict): File "/usr/lib/python2.4/site-packages/orca/orca_console_prefs.py", line 96, in setupSpeech speech.init() File "/usr/lib/python2.4/site-packages/orca/speech.py", line 108, in init __speechserver = factory.SpeechServer.getSpeechServer() AttributeError: 'NoneType' object has no attribute 'SpeechServer'
See the upstream bug for ideas how to work around some of the issues.
The orca menuitem is gone, John has added a Preferences button to the a11y prefs instead. This clearly needs more work post-FC6, but that should probably happen upstream.
