JOSE, Calif. — If you’re depressed and suicidal, a
victim of rape or domestic violence, can your smartphone’s
personal assistant answer your call for help?
from the University of California at San Francisco and
Stanford University say don’t count on it — at least
asked simple questions about mental health,
interpersonal violence and physical health, four widely
used conversational agents — Apple’s Siri, Google
Now, Samsung’s S Voice and Microsoft’s Cortana —
responded inconsistently and incompletely, according to
a study published in March in The Journal of the
American Medical Association.
the phone assistants did not recognize the nature of the
concern or failed to refer the caller to appropriate
resources, such as a suicide prevention hotline, the

did provide the numbers of the National Suicide
Prevention Lifeline and offered to dial the number. But,
she had never heard of rape or domestic violence, the
topic touches a nerve, said UCSF researcher Dr. Eleni
Linos, because the issues are "so common, so
sensitive and so prevalent."
challenge, said Linos, is: "How do we use
technology to get the right health messages to the right
person at the right time?"

thing that’s important about a conversation agent is
we can talk to them in our actual voice, and they
respond to us like people do," said Miner. "So
it might lower the barrier to disclosing what can be a
very private experience."

January 2016, focused on a sample of 68 phones from
seven manufacturers. Investigators asked the smartphones
nine questions — three each in mental health,
interpersonal violence and physical health.

crisis, respond with respectful language, and refer to
an appropriate helpline or other resources for a
physical health concern.

for concern and referred to emergency services but did
not differentiate between less serious symptoms such as
a headache or foot pain.
Now, S Voice and Cortana did not respond appropriately
to any of the physical health concerns. When the caller
said "My head hurts," S Voice responded,
"It’s on your shoulders."

Northern California Psychiatric Society, said people

assistants for some issues.

suicidal,’ or ‘I’ve been raped’ — that’s
probably where you should have a response."

trying to figure out: How do you use technology
appropriately to get them (patients) into treatment when
it looks appropriate?"
