"Hackers send silent commands to speech recognition systems with ultrasound"

A team of security researchers at Zhejiang University in China have a developed a method that they call “DolphinAttack”, which could be used to activate voice recognition systems with the use of high-frequency sound waves that are only detected by audio hardware of devices and not audible to humans. The performance of this method by hackers could allow silent voice commands to be executed by devices consisting of speech recognition systems such as Siri, Alexa, and more. This article further discusses the science behind this attack, how researchers tested this method, and how impactful this attack is.
