A viral video on social networks shows how the Amazon speaker records some voice fragments in which the activation word was not mentioned. Amazon's policy is clear on this: no audio is stored or sent to the cloud unless the device detects the wake word.

A criminologist has not reviewed the more than 500 audio files that Amazon sent her, but in about 50 that she has listened to she found two in which there was no activation word. EL PAÍS has spoken with María Aperador to learn a little more about the recordings.
