I'm assuming you are using Windows 10 -
If you press the Windows key and type, 'Speech Recognition' to bring up the Windows Speech Recognition control panel app, what type of results do you get when you do the training or if you open the Windows Speech Recognition app?
If those are working, would you go into VoiceAttack's Options screen and see what you have selected for, 'Disable acoustic echo cancellation'. Try checking or unchecking that box to see if it makes any difference. What this boils down to is there is something on your system that is preventing the speech engine from receiving audio input. That could be a hardware issue, driver issue, other applications interfering, etc. It could also be a configuration issue, but it looks like you've already got that covered with,
I have already went though the advance tab.
Could you elaborate a little more on what you found in there?
