Being in a position of power can change the sound of your voice, and listeners often pick up on that to figure out who is really in charge, new research finds.

We tend to focus on our words when we want to come across as powerful, but the findings suggest acoustic cues are also important. Markers of more powerful position, for example, may include a higher and louder voice.

“Whether it's parents attempting to assert authority over unruly children, haggling between a car salesman and customer, or negotiations between heads of states, the sound of the voices involved may profoundly determine the outcome of those interactions,” said lead researcher Sei Jin Ko of San Diego State University in California.

It was former U.K. prime minister Margaret Thatcher who inspired the research. “It was quite well known that Thatcher had gone through extensive voice coaching to exude a more authoritative, powerful persona,” explained Ko. “We wanted to explore how something so fundamental as power might elicit changes in the way a voice sounds, and how these situational vocal changes impact the way listeners perceive and behave toward the speakers.”

Ko, along with Melody Sadler of San Diego State and Adam Galinsky of Columbia Business School, designed two studies to find out. The findings were published Nov. 20 online in the journal Psychological Science.

In a first experiment, the investigators recorded 161 college students reading a passage aloud; this first recording captured their voice before any particular high-or-low power status was evident. The participants were then randomly assigned a high- or low-status role in a negotiation game.

Students assigned to a “high” rank were told to go into the negotiation imagining that they either had a strong alternative offer, valuable inside information, or high status in the workplace, or they were asked to recall an experience in which they had power before the negotiation started. Low-rank students, on the other hand, were told to imagine they had either a weak offer, no inside information, or low workplace status, or they were asked to recall an experience in which they lacked power.

The students then read a second passage aloud, as if they were leading off negotiations with their imaginary adversary, and their voices were recorded. Everyone read the same opening, allowing the researchers to examine acoustics while holding the speech content the same.

The researchers found that the voices of students assigned to high-power roles tended to go up in pitch, become less variable in pitch, and become more variable in loudness than the others' voices.

“Amazingly, power affected our participants' voices in almost the exact same way that Thatcher's voice changed after her vocal training,” said Galinsky.

And the students' vocal cues didn't go unnoticed. A second experiment with a separate group of college students revealed that listeners, who had no knowledge of the first experiment, were able to pick up on these power-related vocal cues to determine who did and did not have power: Listeners ranked speakers who had been assigned to the high-rank group as more likely to engage in high-power behaviors, and they were able to categorize whether a speaker had high or low rank with con siderable accuracy.

In line with the vocal changes observed in the first experiments, listeners tended to associate higher pitch and voices that varied in loudness with high-power behaviors. They also associated louder voices with higher power.

“These findings suggest that listeners are quite perceptive to these subtle variations in vocal cues and they use these cues to decide who is in charge,” said Galinsky.
