“…In lie detection, that is, the distinction between truth (accurate) and lies (inaccurate), extensive research has been conducted to find if any vocal characteristics can differentiate truth-tellers from liars. Studies have looked at vocal characteristics such as; talking time (Mehrabian, 1971;Knapp et al, 1974;Todd-Mancillas and Kibler, 1979), speech rate (Anolli and Ciceri, 1997;DePaulo and DePaulo, 1989;Feeley and DeTurck, 1998), vocal immediacy (Kraut and Poe, 1980), vocal uncertainty (Kraut and Poe, 1980;Stiff and Miller, 1986), silent pauses (Anolli and Ciceri, 1997;Stiff and Miller, 1986), vocal pleasantness (Scherer et al, 1985;Zuckerman et al, 1979;Rockwell et al, 1997), vocal stress (O'Hair, Cody, 1987O'Hair et al, 1990) and pitch (Villar et al, 2013;Streeter et al, 1977;Zuckerman et al, 1979;Rockwell et al, 1997). Although these individual studies generally find that the examined vocal characteristic in the respective study does predict accuracy, a meta-analysis of the field has revealed only small effects overall, which is a general issue in lie-detection research (DePaulo et al, 2003; see also Luke, 2019).…”
