Husky tones are the most alluring and the key to successful seduction, scientists have found. Both men and women subconsciously lower the pitch of their voice when they want to signal that they are attracted to another person, a study has shown, reports express.co.uk. Researchers from Albright college in Pennsylvannia tested 48 male and female students, asking them to look at a picture and then leave a voicemail message for that person.

The more attractive the person in the photo, the lower was the tone of voice used in the answerphone message by both men and women.

"When a woman 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," a researcher Susan Hughes was quoted as saying.
