Human speakers manipulate voice acoustic parameters to persuade the audience, achieve goals, arouse emotional states, and convey personality traits (Signorello, 2014). Distinct communication contexts (environmental acoustics, listeners’ biological and social traits) in which the vocal communication (or interaction) takes place influence speakers’ ways to manipulate voice. The voice qualities resulting from the manipulation convey specific type and traits of the speakers’ social image : dominance and biological fitness (Ohala, 1984, 1996), size (Pisanski et al., 2014), physical strength (Sell et al., 2010), age and race (Kreiman and Sidtis, 2011), attractiveness (Klofstad et al., 2015 ; Anderson and Klofstad, 2012), personality traits and affective states (Banse and Scherer, 1996 ; Bänziger and Scherer, 2005 ; Grandjean et al., 2006), and leadership and charisma status (Klofstad et al., 2015 ; Anderson and Klofstad, 2012 ; Signorello, 2014).
This talk will feature several studies that I conducted to investigate voice quality and how it conveys speakers’ social image. The matter was studied comparing distinct genders, languages, and communication contexts. The broad intent of this research was twofold : (a) to discern voice acoustics parameters related to speakers’ evolved vocal behavioral abilities from the ones resulting from linguistically-filtered strategies (used to adapting one’s voice quality to cultural-related expectations) ; (b) to investigate the perceptual salience of voice quality acoustic patterns in triggering specific social behaviors in listeners.
