Women in the Netherlands consistently talk in deeper voices than women in Japan, for instance, and this seems to be linked to the prevailing gender stereotypes – independence versus powerlessness, for instance – in the different cultures (an inequality that is also reflected in a much larger gender pay gap in Japan).Īnd Cheng points out that these changing vocal dynamics may not always be an advantage for women, even in the countries where a deeper speaking voice is now more common. Interestingly, the influence of perceived dominance on vocal pitch can also be heard when you compare voices between countries. Whether consciously or unconsciously, women appear to be adapting their vocal profile to suit the opportunities that are available to them today.

“It signals to others that their intention is to be ready to fight and protect their resources – to assert their status.” And the same connotations were apparent for the humans who had lowered their voices too. And while most of us may not go to such great lengths, recent research shows that we all spontaneously adapt the pitch of our voices to signal our perceived social rank.Īs Cheng points out, it’s a common tactic in nature, with many other primates – from rhesus macaques to our closest relatives, chimpanzees – lowering their vocal pitch during altercations.
WHY IS MY VOICE CRACKING SO MUCH GIRL PROFESSIONAL
Instead, the researchers speculated that the transformation reflects the rise of women to more prominent roles in society, leading them to adopt a deeper tone to project authority and dominance in the workplace.įormer UK prime minister Margaret Thatcher employed a professional speech coach to help her to sound more authoritative, deliberately dropping the pitch of her voice by a massive 60 Hz. Yet the drop in pitch remained even when the team excluded those women from their sample. The team also considered the fact that members of the more recent group from the 1990s were using the contraceptive pill, which could have led to hormonal changes that could have altered the vocal chords. The researchers had carefully selected their samples to control for any potential demographic factors: the women were all university students and none of them smoked. That’s a significant, audible difference. The team found that the “fundamental frequency” had dropped by 23 Hz over five decades – from an average of 229 Hz (roughly an A# below middle C) to 206 Hz (roughly a G#). The researchers compared archival recordings of women talking in 1945 with more recent recordings taken in the early 1990s. Cecilia Pemberton at the University of South Australia studied the voices of two groups of Australian women aged 18–25 years.
