V-STAR & Command Logic

V-STAR is a portion of VMX which we don’t usually really talk about, it does it’s thing in the background and if it does it’s job correctly no-one will ever notice it’s there. V-Star keeps general tabs on VMX’s general operation (V-Star stands for VMX Self Test And Reporting) it makes sure the initialisation sequence has been run, that important paths are set and that the journal is functioning and in the right mode. With VMX 2.2 Dark Edition (and onwards) an addition to V-Star is command logic check. What this does is covers a few of the shorter commands (which may be picked up as false positives by your microphone) and checks to see whether the command in the current chain of events makes sense. So let’s say you’re listening to some mix variants and VoiceAttack incorrectly detects “I’m back”, as in the announcement of being back after initiating “be right back mode”, VMX will know that you couldn’t possibly be announcing that you are back from “be right back” mode because you never declared “be right back mode” in the first place. VMX will know that this is a false positive and will thus block the command from being executed. It does this silently, nothing more than a short amber entry in the VoiceAttack log will be given to the user.

It is, sadly, impossible to cover all commands with this logic as it can only go so far, but in my tests, I would normally receive maybe 1 or 2 false positives per day during long testing sessions (12hours per day), V-Star command logic checks have cut these down to perhaps only 1 false positive execution per week (if that). It has been very effective. Of course it depends on individual’s microphone and detection settings, if you usually found that you experienced false positive command pickups once in a while, you should find V-Star very helpful. However if you experience many false positives i.e every few minutes, this usually indicates either a poor microphone being used and/or a poor listening environment for VoiceAttack. It may also indicate lack of adequate voice training for Windows speech recognition engine, or possibly all the above! In these cases, V-Star may help slightly, but not so drastically.

So that’s V-Star.
