The Medical News said, McMaster University psychologists in Canada want to understand the relationship between the height of the voice and the level of human loyalty. They believe that research will help scientists better understand the evolution of the voice and the way people choose partners.

The team recorded the voice of a man. They increase and decrease the pitch of the voice with audio editing software to create two new clips already. They then asked the volunteers to listen to two clips and then predict the unfaithful in love from the two voice versions.

The process was repeated a second time, but with a female voice.

The results showed that the men who were predictive of men with male bass had a higher level of infidelity than those who spoke tenor. For two female voices, they said, the female voice of the soprano is more likely to be betrayed than the one with the low female voice.

" We found that instinct told both men and women to judge their partner's risk of betrayal through their voice. We all thought that the more attractive someone's voice was, the more likely it was to betray. the higher the person's love , "said Jillian O'Connor, lead researcher, Evolutionary Psychology.

O'Connor said that betrayal in love not only caused negative emotional impact, but also resulted in financial loss and the risk of family breakdown. Therefore, in the process of evolution, human beings have always avoided romantic relationships with unfaithful people. Instinct teaches people how to identify them by voice. Most women think that men who have a deep voice are more likely to betray love. In contrast, most men rated the risk of unfaithfulness in women with higher voices than those with low voices.

Professor David Feiberg, a member of the research team, explained that the pitch of the voice has a relationship with hormones and the flower version. In men, the higher the level of testosterone (male sex hormone), the lower their voice. In contrast, women with high voices often have large estrogen levels.

" The higher the concentration of testosterone and estrogen in the body, the greater the risk of human adultery. Our findings show that each person, somehow, recognizes this relationship and always remembers it. in the process of finding a partner , "Feiberg said.
