During interpersonal interactions, individual perceptions and judgment are unavoidably influenced by speech cues,such as vocal pitch. This paper experimentally examines the effect of vocal pitch on risk attitudes. In a lottery-choicetask, subjects made a series of binary choices between a 50–50 lottery and a sure outcome option and were asked tolisten to a voice recording verbalizing the payoff information of these options. We manipulated the vocal pitch of thevoice recordings and administered three treatment conditions: control, low-pitch, and high-pitch. We found that ahigher-pitched voice increased risk aversion, while a lower-pitched voice raised risk tolerance. As a relatively smallsample size was employed, the results should be considered preliminary; future replications are indeed necessary toconfirm the robustness and generalizability of the findings.
