How to Understand Dogs?
Humans are good at understanding others' feelings from the sounds they make. A baby's laugh tells us he or she is happy. Similarly, we have no trouble (know) that a dog's energetic bark is a sound of joy.
In fact, the earlier studies have shown we're good at telling the(different) of the dog's barks. Are there similar features that we hear of a baby's laugh, a dog's happy bark or a man's angry cough? A team of researchers designed survey to know about how humans realized the feelings of dogs from their sounds. Thirty-nine people (invite) to take the survey. They listened to sounds any expressions. The volunteers judged each sound through (it) emotional class.
The(researcher) results showed a special relationship between how the listeners learned the feeling of each sound and its sound science. This way, (short) calls were regarded as more positive ones than longer calls. By these same simple rules, they came to a conclusion: It may be possible to (easy) recognize man-made feelings in social robots.
