Few more tips.
If
voice out this did not work right away, just change the delay time as shown at the picture above, in most cases this will activate the voice out engine.
All Microsoft packages named as SDK, they include tools for developers.
You do not have to use them, but its good to know that they are there.
In my case, Keysight Handheld Meter Logger, this activated
voice out at highest sound quality with out user interference.
TTSAppVB.exe this is the GUI that you may use to explore all available Voices and or sound quality settings in your PC, and do not worry of changing settings, there is no permanent change by using the
Speak button.
TalkBack.exe this will activate windows speech recognition wizard, I did not follow this route (making any changes), as there is no need to do that.
