Men with higher testosterone are linked to having much attractive voices. Having more testosterone makes a man's voice deeper, which is deemed more sexy by women. Also, men with deep voices are more probable to having children due to higher testosterone levels.
These type of men often have broader shoulders, and a more symmetrical figure. They also tend to have more sexual partners.
Female voices are found to be more attractive during their ovulation period, when conception is at a higher risk. During menstruation, their voices tend to be less attractive, possibly due to less chances of conception.
People with attractive voices tend to have lost their virginity at a very young age. Also, voices are able to reflect one's state of mentality and emotions.
Actually, I do find certain voices rather appealing, and some as annoying. However, I never thought of such relations to seeming simple concept of voices. Voices aren't just tools in communication, they also tend to reflect one's attractiveness and features, or so researchers say.
