A team of researchers from Germany's Darmstadt University, France's University of Paris Saclay, and North Carolina State University has developed a Raspberry Pi-based device that eventually may be able to warn users when Amazon's Alexa and other voice assistants are snooping on people.
The researchers said the $40-prototype LeakyPick tool detects the presence of devices that stream nearby audio to the Internet with 94% accuracy.
LeakyPick periodically emits sounds and monitors subsequent network traffic to identify audio transmissions, triggering an alert whenever the identified devices are confirmed as streaming ambient sounds.
LeakyPick also tests devices for words that incorrectly trigger the assistants, having to date found 89 words that prompt Alexa to send audio to Amazon.
