Its not as interesting as it sounds unfortunately, you may have heard recently there have been many concerns raised into the internet-linked smart speakers with built-in microphones or cameras snooping on private conversations or moments.
Well Amazon are doing their best to counter this and on the 29th May 2019 added the skill to Alexa to forget what it has heard. The command “Alexa, delete everything I said today” will mean Alexa does just that.
Alexa is the Artificial Intelligence behind the Amazon systems and now the new feature has been introduced it will go on the Alexa privacy hub, providing controls for information shared with or by Echo devices, which also allow microphones and cameras to be turned off. Microphones and cameras on Echo smart speakers can also be turned off.
