[orca-list] How to install orca in debian wheezy

[David Effendi <deffendi gmail com>]

Hello,

I tried to install orca in debian wheezy by executing the following:
sudo apt-get install espeak speech-dispatcher at-spi
sudo apt-get install gnome-orca

but it was not successful. When I run orca, the spash screen shows up
but I kept getting dummy speech ( "This is the dummy output module
..." )

does anyone know hat I am missing?
If a plain vanilla debian based distro doesnt have orca pre installed,
what can I do to install it myself?

Many thanks in advance!

David
