Vocal Preferences in Humans: A Systematic Review

Abstract

Surprisingly, the study ofhuman voice evolution has long been conducted without any reference to its biological function. Yet, following Darwin’s original concept, John Ohala was the first linguist to assume the functional role of sexual selection to explain vocal dimorphism in humans. Nevertheless, it is only at the very beginning ofthemillennial that the study ofvoice attractiveness developed, revealing that beyond its linguistic role, voice also conveys important psycho-socio-biological information that have a significant effect on the speaker’s mating and reproductive success. In this review article, our aim is to synthesize 20 years of research dedicated to the study of vocal preferences and to present the evolutionary benefits associated with such preferences.
