Whether the speech synthesis is dictionary based is not the point. The  
point is, can a screen reader reasonable have *a* dictionary for its  
speech language. In many cases, the platform provides spell checking,  
so a screen reader could test if a string spell checks successfully to  
make a guess if speaking it will be any good.
