[orca-list] Orca on my OLPC

[pascal diogoantunes org]

Hi, I have on OLPC with Orca installed.
But when i run Orca on Gnome, it runs very well (no error messages),  
but i hear nothing.
I'm sure the sound works (videos and music prove me).
I don't if it's the system of voice, but orca writes me that I have  
the gnome service voice and the festival gnome speech driver installed.
I'm on fedora 11.

Thanks in Advance.
