Consumers are worried machines by Amazon and Google are eavesdropping on them at home, but that’s not stopping purchases.

Despite increasing concerns about “passive listening” and privacy risks, more people are buying smart speakers like Amazon.com Inc’s Echo and the Google Home, according to a Capgemini Research Institute report released Sept 5. Almost half of the survey’s 12,000 respondents who live in the US, UK, France and Germany have a voice-activated device, up from 25% who reported owning one in November 2017. However, 52% were worried their voice assistants were listening to their private conversations.
