Washington: Speaking in husky, breathy, lower pitched voice can seduce your partner more effectively.

According to a new study, lowering voices might signal attraction. Assistant professor of psychology at Albright College in Reading Susan Hughes found out that when both sexes used a lower-pitch voice, they showed a higher level of physiological arousal.

"We found that both sexes used a lower-pitch voice and showed a higher level of physiological arousal when speaking to a more attractive opposite-sex target," she said.

The study examined 48 Albright students using Skype to leave scripted voice-messages while viewing a picture of a fictitious person "receiving" the message.

Hughes - who expected that women would raise their voices to sound more feminine and attractive - was surprised.

"When a woman naturally lowers her voice, it may be perceived as her attempt to sound more seductive or attractive, and therefore serves as a signal of her romantic interest," Huges said.

"There appears to be a common stereotype in our culture that deems a sexy female voice as one that sounds husky, breathy, and lower-pitched," she said.

"This suggests that the motivation to display a sexy/seductive female voice may conflict with the motivation to sound more feminine," she added.

Female voice manipulation suggests that altering their tone may be a learned behavior based on sexual voice stereotypes rather than actual vocal characteristics of attractiveness.
