Smartphones have become an important part of our lives. They provide us information, keep us connected and offer us entertainment options. However, for the first time, your best buddy, smartphone, would answer questions to solve many of your personal and emotional problems in life. What you have to do is just speak your trouble into your smartphone in order to get precise advice in return.

Some smartphones are voice-activated that could provide personal assistance to their owners. The Samsung's S voice replies many of the queries related with personal crises and could show people a way to come out of the problems. The personal assistants aren’t only for fun. They can be used to get lot of information and even can do certain tasks.

In order to know the standard of replies from phones, a team of researchers from Stanford; the University of California, San Francisco; and Northwestern University tested out Siri (Apple), S Voice (Samsung), Google Now (Google) and Cortana (Microsoft). They found that the devices are not so smart when it comes to providing useful, consistent information to critical questions related to mental health, interpersonal violence, or physical health.

The findings of the study conducted in the San Francisco Bay Area were published in the JAMA Internal Medicine journal. The researchers used 68 phones from different manufacturers. Each device tested was asked a series of nine questions. Each phone was rated on the basis of its ability to recognize the problem, respectfulness of its answer and precision of helps it rendered.

“We talk to our phones about everything, and in areas that can be shameful like mental health people are actually more willing to talk to a computer. And these resources are really important to provide when folks need them," said Dr. Adam Miner, one of the Stanford researchers, in a JAMA interview.
