Siri saves teen in US

Siri - Apple's voice-activated assistant - may have saved the life of Tennessee teenager after he was pinned underneath his truck and unable to reach his phone.

Sam Ray was alone when the truck he was fixing fell on him, but he remembered his phone was in his back pocket.

Ray used his bottom to activate Siri, which called emergency services.

The dispatcher thought it was mistaken call at first but soon heard  Ray's cries for help.

"I could feel myself slipping," Ray told his local newspaper the Tennessean on Friday. "I was starting to accept that I wouldn't get out."

The dispatcher was able to locate Ray's home in a suburb of Nashville by triangulating the signal from his mobile phone.

Full recovery

Rescue workers pulled Ray from underneath the truck, and he quickly was airlifted to a nearby hospital.

He was seriously hurt in the July incident, suffering several broken ribs, a bruised kidney, cuts, a concussion and burns to his left arm. He has since recovered.

Ray had been thinking about getting a Samsung Galaxy phone, but the accident has changed things.

"I guess I'm stuck with an iPhone for the rest of my life," Ray said. "I owe them that."
