One of the interesting themes that came up during consultations was the issue of privacy – who has access and what does an Amazon Echo or Google Home data stores / collect?
Behind all this lies the more serious question of privacy: what happens to the data collected by voice-activated devices such as Amazon Echo and Google Home, and who is able to access it? Most recently, US police investigating the case of an Arkansas man, James Bates, charged with murder, obtained a warrant to receive data from his Amazon Echo. Although Amazon refused to share information sent by the Echo to its servers, the police said a detective was able to extract data from the device itself.
The case not only puts Alexa in the futuristic position of being a potential key witness to a murder, it also raises concerns about the impact of letting a sophisticated virtual assistant – a market estimated to be worth $3.6bn by 2020 – into our homes. As Megan Neitzel, the mother of the girl who wished for a doll’s house, put it: “I feel like whispering in the kitchen … I [now] tell my kids Alexa is a very good listener.”
