People judge you by your voice in many ways.
The result: speakers with higher-pitched voices were judged to be less truthful, less emphatic, less potent, and more nervous than speakers with lower-pitched voices. Also, slower-talking speakers were judged to be less truthful, less persuasive, and more passive than people who spoke more quickly. “Fast-talking” may be a cliché description of a sleazy salesman, but chances are, a little speedup will make you sound smarter and more convincing. And if two speakers utter exactly the same words but one speaks a little faster and louder and with fewer pauses and greater variation in volume, that speaker will be judged to be more energetic, knowledgeable, and intelligent. Expressive speech, with modulation in pitch and volume and with a minimum of noticeable pauses, boosts credibility and enhances the impression of intelligence.
When you hear a woman’s voice talking about relationships you trust it more than a man’s voice, even if the content is the same. You like a forceful male voice more than a forceful female voice, again, even when the content is the same.
Those who had female-voiced tutors for the love-and-relationships material rated their teachers as having more sophisticated knowledge of the subject than did those who had male-voiced tutors, even though the two computers had given identical lessons… students who heard a forceful male-voiced computer tutor rated it as being significantly more likable than those who heard a forceful female-voiced tutor, even though, again, both the male and the female voices had uttered the same words.
Women find men with deep voices sexier.
…women miraculously tend to agree: men with deeper voices are rated as more attractive. Asked to guess the physical characteristics of the men whose voices they hear in such experiments, women tend to associate low voices with men who are tall, muscular, and hairy-chested— traits commonly considered sexy.
And men with deeper voices have more kids.
The researchers found that while the pitch of women’s was not a predictor of their reproductive success, men with lower-pitched voices on average fathered more children.
Men subconsciously know the connection between voice and dominance. When they feel powerful in a group they deepen their voice and when they feel weak they raise it, unknowingly.
And the researchers found that when the participants believed they were physically dominant— that is, more powerful and aggressive— they lowered the pitch of their voices, and when they believed they were less dominant, they raised the pitch, all apparently without realizing what they were doing.
