system.speech not recognized in c# expres?
===

I am using c# 2010 express

And i want to do speech from a wav to text 
However when i type on top of my prog.

     Using System.Speech ;  // Then Speech is not recognized
     //



     // the bot runnning the website wants to see some code or else i cant post here
     while(n!=J){
     i=*j[n];
     counsole.out(&j);
     n++;
     }
     

Just to be sure i installed the system speech sdk from MS but no difference.
I am using .net 4.0 client profile.. what should be ok i think.
What should i do to resolve this ? is it a limitation of c# express or ??
