How to Tell If Someone Is Happy or Sad on the Phone

How to Tell If Someone Is Happy or Sad on the Phone
Scientists have come up with some researches on what makes different types of people“tick”.
The scientists at the University of Cambridge have developed new mobile phone technology called Emotion Sense that can tell if a caller is happy, angry or sad.
Scientists hope to fit the speech recognition system to standard mobile phones and use it to determine emotions—it will also use a GPS tracking system to log where the call is made.
 And they’ve already made some pretty major breakthroughs into really getting under the skin of us humans.
The results from the pilot scheme make interesting scientific reading. Among the key revelations (﹦facts) are that callers feel happier at home and sadder at work.
To break it down, scientifically, it shows 45 percent of all emotions produced at home are “happy”and 54 percent of emotions at work are “sad”.
Meanwhile, people show more “intense”(﹦nervous) emotions in the evening than they do in the morning.
Of course, this could just be because most people feel too tired in the morning to get overly “intense”. Eating breakfast and getting to work on time is usually enough of an achievement.
Anyway, the Emotion Sense technology has been developed by psychologists(心理学家) and computer scientists who say it uses speech recognition software and phone sensors(传感器) attached to standard smart phones to judge how callers’ emotions are changed by everyday factors.
The sensors analyze voice samples and these are then divided into five categories: happiness, sadness, fearfulness, anger or neutral-—boredom or passivity(消极) would fit into this last category.
