Want to know if your partner’s cheating on you? Just listen to their voice

Abstract

First paragraph: Picture Morgan Freeman, Donald Trump or Margaret Thatcher. Most likely you can hear their voices in your mind, and the characteristic inflections that they put on certain words, as well as their tone and pitch. Even without listening to the words, when you hear someone speak you can pick up important information about them from characteristics such as how loud or deep their voice is. At the most basic level, voices convey biological characteristics such as whether someone is male or female, their body size and physical strength, age and sexual maturity. For example, Donald Trump’s voice can signal to you that he is a man, and that he has passed middle age. But did you know that voices can also signal a person’s attractiveness, fertility and even the likelihood of them being unfaithful?
