Abstract

Low fluctuating asymmetry (FA, a measure of deviation from bilateral symmetry) appears to be a phenotypic marker of reproductive viability and health. In the present study, we investigated whether ratings of voice attractiveness were correlated with variations in FA. Several bilateral traits were measured to calculate a FA index and independent raters who did not know and never saw the subjects assessed the attractiveness of recordings of each subject's voice. Voices of subjects with greater bilateral symmetry were rated as more attractive by members of both sexes than those with asymmetrical traits.
