Siri helped a quick-thinking boy in England save his unconscious mom’s life.

Roman, 4, used his mother’s thumb to unlock her iPhone before asking Apple’s voice assistant for help after she passed out at their home in Croydon, South London, on March 7.

Siri dialed the emergency service number and the child informed a dispatcher what had happened. Heartbreaking audio, above, captures Roman saying his mom is “dead” because “she’s closing her eyes and she’s not breathing.”

Paramedics arrived on the scene 13 minutes later, revived the unidentified woman and took her to the hospital. Authorities have not revealed what caused her to fall unconscious.

“It’s an amazing story,” Chief Superintendent Ade Adelekan, from London’s Metropolitan Police Service, said in a statement.
