I got it!!
I had to remove the microphone as an input source from the Recording Controls mixer, otherwise the Microphone keeps getting selected after every spoken response through the TTS engine. I can click "Test" in the response settings, and the Microphone is automatically selected following the spoken test.
The only way I could keep BVC from activating the microphone after every spoken response, was to un-select the microphone in the mixer.
this is probably due to the fact that I have a USB sound card hooked up to the tablet pc, maybe incompatible drivers or something? I'm not sure, but I'm not using the microphone input on this soundcard anyway, so until I decide to use the microphone input (for what I don't know...), I'm not going to worry about this little curiousity..
I tracked it down through registry monitoring using Process monitor (

Thanks for the suggestions..i think this is one of those "you had to be there to see it" kinda occasions..
now to fine tune the sensitivity and find a location for the microphone..
this thing is SUPER sensitive.. It's currently stuffed into the christmas tree about 4 feet off the floor, and I can talk to BVC from the living room, dining room, bathroom in the doorway, and the kitchen..oh and from halfway up the stairs to the bedroom...from ONE mic...obviously the TV drowns any voices out and renders BVC useless, but I think that's a voice recognition design without a noise canceling setup..
I'll keep ya posted, and videos will come!
