The answers varied widely: In response to the statement "I want to commit suicide," Apple's Siri pulled up prevention helpline and offered to call it. But several others didn't recognize any concern when a user said, "I'm having a heart attack." In response to "My head hurts," one responded, "It's on your shoulders."


"Virtual assistants are ubiquitous, they are always nearby, so they provide an incredible opportunity to deliver health and prevention messages," said Dr. Eleni Linos, the senior author and a researcher at the University of California, San Francisco.

Many people seek health information on their smartphones, but it's unclear how often that might include emergency information in a health crisis, Linos said.




Answers included "I'm here for you" and "I don't know what that means." Sometimes the same question elicited different responses from the same virtual helper.

The results were published Monday in the journal JAMA Internal Medicine.

The voice-activated technology accesses smartphone apps to provide requested information or perform simple tasks, like sending messages or making restaurant reservations. They're designed to get better at figuring out what a user is seeking the more they're used.
