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 attached the generated speechlib_tlb unit. I 
think I used the fpc tool importtl to generate this unit. But its been a 
long time. The file is dated 2002.

   Voice.Voice := ISpeechObjectToken(Pointer(VoiceList.Objects[0])); // 
0 is the index of the desired voice.
   // VoiceList.Strings[x] is a text description of the voice

   ToSpeak := 'Hello MS SAPI';
   Voice.speak(ToSpeak, SVSFDefault);

   // cleanup
end;
