Smart speakers might be able to do more than mere voice-based home control-- ABC News reports an alleged assault could have turned ugly if a smart home device did not inadvertently call the police.
The incident happened in a town outside of Albuquerque, New Mexico, where one Eduardo Barros was house-sitting a home with his girlfriend and daughter. According to the police, the couple got into an argument that got physical. At one point, Barros threatened to kill his girlfriend with a firearm, asking her "did you call the sheriffs?" An unspecified smart speaker connected to the house surround system picked up the message, recognised it as "call the sheriffs," and proceeded to do exactly that.
Thus, following the spot of Minority Report-style crime prevention, the police arrived at the scene. The girlfriend and daughter were saved, and crisis negotiation and SWAT teams managed to take Barros into custody after an "hours-long stand-off."
