#3This is MUCH bigger deal than most understand. This will cost less than $10 to build and their is no hardware solution on phones or Alexia.
Phreaking is back.

This will be fixed with a simple software update that ignores all sounds at inaudible frequencies.

Except the inaudible sounds are used for marketing purposes. Most companies aren't going to want to just close that door.

#9Even if the commands are not inaudible it's a security issue if the device performs a dangerous action because someone in the neighborhood said something.
The feature is presented as if it only responds to the owner but realistically that distinction doesn't work at all.
If you shout 'hey Siri' into the microphone at a large event, a lot of phones are going to respond.

If you were to read the article you'd see this isn't how it works. They're inducing harmonic signals within the speech passband.
