Barros pulled a gun and threatened to kill his girlfriend asking "Did you call the sheriffs?".
Google's smart voice assistant product has made headlines in the states, after it called police to a home in New Mexico during a domestic dispute. Police say that Eduardo Barros was house-sitting at the residence with his girlfriend and their daughter.
"This fantastic technology definitely helped save a mother and her child from a very violent situation", said Bernalillo County Sheriff Manuel Gonzales III.
The boyfriend reportedly said to his partner, gun still in hand: "did you call the sheriffs?" when something unbelievable happened. Who knew that smart speakers, capable of searching for information and placing online orders, could also help against crime?
They intervened and took the woman and her daughter away; she was she had been hit and kicked, but did not need to be hospitalized, officials said. Her daughter was unharmed, Romero said.
Barros was taken into custody and apparently remains in jail facing charges of assault and the possession of a firearm by a felon.
His girlfriend was taken to the hospital with injuries sustained during the altercation.
"The unexpected use of this new technology to contact emergency services has possibly helped save a life", Barnalillo County Sheriff Manual Gonzales III said in a statement.
For owners of smart speakers, having the device accidentally initiate a command is mostly quite hilarious, especially when it attempts to call someone or play a song when it detects a specific sentence in a conversation and misinterprets it for an actual command.
It was first reported that the device was a Google Home device, but this was later changed.
It wasn't until April this year that Amazon agreed to hand over the data.
Such instances, however, also remind users that smart speakers are always on, which may cause inconveniences such as wrongly ordered dollhouses and concerns on privacy. Authorities said that the smart speaker might have saved a life by calling 9-1-1 when it did.
