Inaudible sounds can activate AI assistants


In May 2018, researchers in the US and China demonstrated that they could send commands that activate Apple's Siri, Amazon's Alexa, and Google Assistant but that are inaudible to the human ear. The researchers were able to make smartphones and smart speakers dial phone numbers and open websites; the potential is there to make them operate Internet of Things devices, wire money, or execute retail transactions by hiding commands in music or other audio.
