Speech unrecognized

I started to develop my own css from the one in the documentation (CSS 2) 
as suggested.
But when I tried it with the validator I received some error. So I tried 
the original (from the documentation) without modification.
Here is the result. Basically the validator does not recognise the speech 
media and give an error on the @page.

About the example in the doc I would suggest to fix the warnings.
