Emergency detection. You're walking in the alleyway. Unfortunately, there's a gang there. They're coming after you. You know that if you call 911, they'll definitely kill you. Luckily, you don't have to. Siri was kind enough to talk to a police dispatcher for you. You wake up in the middle of the night because the smoke alarm is going off. You can confirm there's a fire! Oh, no! Luckily for your sleeping neighbors, Siri knows there's a fire and is talking to a fire dispatcher right now. She will even tell the dispatcher if there is any animal, human or dog, that could be trapped! You're having another heart attack? No problem, Siri heard your complaints and could verify you're probably having a heart attack, and is talking to an EMS dispatcher. You fell unconscious? No problem, Siri heard you collapse and told the dispatcher accordingly. The alarm went off at your house. Siri's on the job yet again. She will do everything she can to see if the alarm was triggered on accident. If you're not home, that means she will text everyone who has an access code - if nobody says yes in 5 minutes, she'll assume something's up.
