Recognize Stress using Smartphone

In this growing technical world everything is on our finger tips. The smartphones especially are making the world to relax and is not letting them work. But simultaneously it is making us advanced in each field.

Smartphones may soon be able to tell you where you come across the most stress with the help of a new software that has been developed to identify stress from the patterns in your voice.

Stress Sense is first trained to recognise a person's unstressed voice.

To do so, the users must relax and read a 3-minute passage from a book into their phones.

The system then compares this recording to its pre-programmed knowledge of the physiological changes that stress induces like speaking at a faster rate and a clipped frequency spectrum.

It then takes note of any instances of stress it detects in the voice.

"Our stress model also adapts to different background noise environments," New Scientist quoted Hong Lu of Intel in Santa Clara, California, who developed the system, as saying.

In tests that included putting volunteers through mock job interviews, the researchers found their prototype's stress-recognition accuracy to be 81 percent indoors and 76 percent outdoors, where sound quality wasn't as good.

The team plans to make the system a plug-in to an Android application called BeWell, which uses a phone's accelerometers and GPS sensors to record users' activity and sleep levels.

Smartphone users will be able to set StressSense to either listen to their voice throughout the day, or only to activate when they are having a phone conversation.

The app will be presented at the Ubicomp conference in Pittsburgh, Pennsylvania, next month.

So guys gear up for your new smartphone app, and make your life easy and advanced.
