From MS:
"Of course this would be heard and the actions taken would be visible to the user if they were in front of the PC during the attempted exploitation." Bah. I bet some degree of stealth could be worked into this if someone tried hard enough. The most obvious method won't work: emitting sound outside the range of human hearing. The intersection of the sets of frequencies that a normal microphone will detect, a normal speaker will emit, and human ears won't detect is null. There are other avenues that would have to be explored experimentally. How much can you speed up or slow down the words and the recognition still work? What about overlaying the commands on music? Can we take advantage of psychoacoustics to disguise some of the phonemes, so an unalert user might not notice their presence? I just wouldn't assume this is inherently non-stealthy. - Ken On 2/1/07, Juha-Matti Laurio <juha-matti.laurio () netti fi> wrote:
