You have to call flush. It's the same as with fwrite/fflush for file I/O.
It makes things easy to use: If you want, you can send single characters.
When you want to make sure the text is spoken, you flush. The synthesizer
may speak earlier when it has a complete sentence, but it is not starting
on half words or half sentences.

I suppose we can get the coniguration variables from KConfig?

The rest of the API sound reasonable for me.
