Chinese security researchers have discovered a way to send secret, inaudible commands to speech recognition systems such as Siri, Amazon Alexa, and Google Home using ultrasound. A team from China's Zhejiang University devised the technique, which they have dubbed "DolphinAttack". Now, it's important to stress that this is a *potential* problem....
