It might be a good idea to integrate the jspeaker plugin in Chamilo 1.10.
The jspeaker plugin "reads" the given DOM element's content, so it should be possible to have a special right-click event on all Chamilo documents (only when the plugin is enabled, which should also be possible to enable by student through a specific profile field).
This would make it more accessible, but I'm not sure how really useful it would be.
For people using their laptop while cooking (like me), it would be nice to select a large document (or learning path) and say "read it to me", but I don't see clearly how still (I think it should be possible, though).
Setting it for 1.10, but it could really be moved to later if not feasable...
