Editing Vocal range (section)

== Evolution of sexual dimorphism in human voice pitch ==
The upper pitch range of the human voice is, on average, about half as high in males as in females.<ref>Titze, I. R. (2000) Principles of voice production. Iowa City, IA7 National Center for Voice and Speech</ref> Even after controlling for body height and volume, the male voice remains lower. [[Charles Darwin]] suggested that the human voice evolved through intersexual sexual selection,<ref>Darwin, C. (1871). The descent of man, and selection in relation to sex. London: Murray</ref> via female mate choices. Puts (2005) showed that preference for male voice pitch changed according to the stage of the menstrual cycle<ref>{{cite journal|last1=Puts|first1=D.
