>>> Smartphones help to avoid stress

Intel (USA) has developed a StressSense system that allows one to identify a person's normal voice. To do this, the user has to relax and read a snippet of the book that lasts 3 minutes for the phone to record.

StressSense will tell whether the user is stressed or not.

StressSense will then compare this record to a database of stress-related physiological changes, such as faster read speeds, shorter frequency ranges, and then record any stressful performance. detection system.

"Our stress model also adapts to different background noise environments ," said Hong Lu of Intel, StressSense's developer.

Voluntary trials showed that StressSense's accuracy in detecting stress was 81% (indoor) and 76% (outdoor, where sound quality was lower).

The StressSense development team will put the system into an Android-based application for smartphones.
