Bloomberg reported in April 2019 that Amazon employed thousands of workers worldwide who listened to Alexa recordings captured in users' homes. Workers heard 'confidential medical information, drug deals, and recordings of couples having sex.' Apple contractors listened to ~1,000 Siri recordings daily, including unintentional activations. Google Assistant did the same. All three companies initially failed to disclose that humans were reviewing recordings. Apple and Google temporarily suspended the practice; Amazon eventually let users opt out.
