Build a parasite to block your digital assistant

Digital assistants offer convenience, but they also offer continuous surveillance, and it’s not always clear when the tech is listening. Alias by Bjørn Karmann is a device you put on top of the assistant the block any unwanted listening:

Alias acts as a middle-man device that is designed to appropriate any voice activated device. Equipped with speakers and a microphone, Alias is able to communicate and manipulate the home assistant when placed on top of it. The speakers of Alias are used to interrupt the assistance with a constant low noise/sound that feeds directly into the microphone of the assistant. First when Alias recognises the user created wake-word, it stops the noise and quietly activates the assistant with a sound recording of the original wake-word. From here the assistant can be used as normally.
