A long time ago I played with MS sapi. I will try to put the relevant 
code here for you. My goal was to put the output speech into memory to 
be processed further.  I think I used the fpc tool importtl to generate 
the  Speechlib_tlb unit. But its been a long time now. I can email you 
directly the file if you want.
