Wondering if you’ve got a cheater on your hands?

Just listen to them speak. According to a new report, you can detect infidelity by a person’s voice.

Researchers from Albright College and Penn State recently conducted an experiment, published in Evolutionary Psychology, to determine the connection between speech and infidelity.

To do so, they examined the recorded voices of 10 men and 10 women counting from one to 10. All voices were from heterosexual, white and unmarried individuals who were committed relationships. 

Researchers even created two versions of the samples -- a high-pitched one and a low-pitched one -- to assess if tone played a role in their analysis. They then scouted participants, who did not know the people from the audio or their backgrounds, to listen to the voices.

They found that listeners “rated the voices of those who had a history of cheating as more likely to cheat,” the study said. 

They were also able to mostly distinguish the cheaters from the noncheaters despite the different pitches.

While the researchers couldn’t pinpoint why the participants were able to detect infidelity, they attributed their finding to factors including clarity of articulation and personality traits.

“For example, masculine males tend to display less clarity in their speech and show phonetic patterns indicative of masculinity, which in turn could be associated with infidelity threat,” the study said. “Extroverts show greater variation in fundamental frequency, greater voice quality, and fewer silent pauses … and high extroversion strongly predicts infidelity.”

Researchers are hoping to conduct more experiments with larger sample sizes for further investigation.
