Participants listened to short clips from 100 celebrities recognized for their appealing vocal qualities. They evaluated these voices using scientifically validated criteria associated with a more sexually enticing vocal presence. These criteria include:

1. Pitch: Research indicates that individuals, both men and women, often find lower voices of the opposite sex more attractive.

2. Speed: Speakers who maintain a slightly faster pace are generally perceived as more attractive and confident.

3. Volume: Psychologists have determined that individuals with louder voices tend to be perceived as more attractive.
