Smart speaker recordings reviewed by humans

Amazon, Apple and Google all employ staff who listen to customer voice recordings from their smart speakers and voice assistant apps. News site Bloomberg highlighted the topic after speaking to Amazon staff who "reviewed" Alexa recordings. All three companies say voice recordings are occasionally reviewed to improve speech recognition. But the reaction to the Bloomberg article suggests many customers are unaware that humans may be listening. The news site said it had spoken to seven people who reviewed audio from Amazon Echo smart speakers and the Alexa service.
