Hello,
After some research I have found that I can use an ActiveX object to
speak text.
It is set up with:
speakIt = CreateStaticObject("Sapi.SPVoice");
and is called with:
speakIt.Speak("text to say");
The difference from the Say() command is that it halts the AFL until
it stops speaking.
This would certainly be useful for things like debugging where you
could make it say a value in a tight loop, and it would slow down the
loop, saying each value. Better have a way to break out of the loop
though if it is a long one.
Using this command would make sure that every spoken output is
completed. However, I still want to just buffer up the messages and
let the chart continue to run full speed.
I have spent quite a while trying to find the object that will tell me
the busy status of the speech engine. Very frustrating search so
far. MS Docs %^$^@%#^#^!
Anyway, I hope this extra bit can be useful to others.
Best regards,
Dennis
