Lauren Hockenson, writing for GigaOm:
With an update to phones running iOS 6 and iOS 7, Siri now reacts with a strong, two-fold approach when mentions of suicide come up. First, the assistant offers the number of the National Suicide Prevention Lifeline and will even offer to call directly — a new feature that makes seeking help as simple as clicking “yes” on the phone. If for whatever reason the user decides to select “no”, Siri does a search of all local suicide prevention centers, offering a list and directions powered by Yelp.
This is a terrific feature — wish I’d known about it earlier.
