Smart office secrets: Alexa, Siri, and Google Assistant could hear commands the human ear can't

Researchers at several universities in the United States and China have developed a method of manipulating white noise to trick digital assistants into executing commands.

Called "adversarial audio," the trick involves creating "a special 'loss function' based on CTC [connectionist temporal classification] Loss that takes a desired transcription and an audio file as input, and returns a real number as output," said U.C. Berkeley PhD candidate Nicholas Carlini.

The manipulating recording is run through a process called gradient descent until the distortion is minimized but still effective at triggering a response from digital assistants like Siri, Alexa, and Google Assistant.
