  • The effects of voice pitch and resonances on assessments of speaker size, masculinity, and attractiveness 
    Pisanski, Katarzyna Alicja; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Dept. of Psychology, 2010Arts and ScienceDepartment of Psychology, 2010)
    The human voice might have been shaped by sexual selection. Hence, voice fundamental (F0, or pitch) and formant frequencies (Fn, or timbre) are proposed to convey fitness cues germane to rivals and potential mates. First, ...
