Audio is a terribly insecure channel to accept commands through. You presume no one else has access to the device because it is physically locked in your house, but sound travels through walls and through speakers. Heck, you can even make a window pane into a speaker with some simple gear.
It's no big deal when the worst case scenario is being served up a search result you don't need or listening to a song you didn't request, but you definitely wouldn't want to link voice recognition tech up to anything non-reversible like a stock trade or the lock on your front door.
- nomel 9y agoIn case anyone missed it, the commands don't have to be audible: From https://arxiv.org/pdf/1708.09537.pdf https://arxiv.org/pdf/1708.09537.pdf > DolphinAttack ... modulates voice commands on ultrasonic carriers ... to achieve inaudibility. By leveraging the nonlinearity of the microphone circuits the modulated ... commands can be successfully demodulated
- Sargos 9y agoYou can already order products on Alexa/Home. Home knows voices of specific users so it can accept or deny commands based on who is saying the words.
- krapp 9y agoYeah, but it's the way it was done in Star Trek, and many of the engineers creating the technological future want that future to behave like Star Trek. Voice command isn't a technically superior user interface, it's just more "futuristic." And <tangential rant> it shouldn't be mandatory. If I want Cortana or Siri or Alexa, let me download and install it. Don't FTLOG integrate it so deeply into an operating system that it's all but impossible to avoid </tangential rant>
