Re:Re: Speech enabling GnomePanel

[Jaideep <jdthe_boss yahoo com>]

Thanks Bill,
Thank you very much for the help. Initially i was
trying to do it all for the GNOME system, but I
thought that would be too complex. I was not aware of
the AT-SPI then. Now I have started reading about this
API. I hope I will be able to figure out what needs to
be done. Thanks once again for your tips.
-Jaideep.
