Can a windows service speak via the text-to-speech API?

Question

I have a project that would like to speak (text to speech, TTS) from inside a Windows service. I understand that no GUI is available inside a Windows service. Will the speech API work inside a service?

Answer 1

GUI is avaivable inside a Windows service. See SERVICE_INTERACTIVE_PROCESS in WinNT.h and this link. And yes, SAPI will work inside a service in the same way as it does in desktop apps.
