text: I mean don't get me wrong it a good tool it see people emotional . But that why we got eyes for , to look and see things .We dont need computer to see people emotional we can tell by the way a person talk . If that person sound like he or she got a additon (come back) that mean that person is in a bad mood and don't want to talk at that time . A computer wouldn't even know he or she in a good mood or not by the way they talk. Another good reason why it's not valuable.
