Abstract
This paper argues that the results presented by Mayew and Venkatachalam in “The Power of Voice: Managerial Affective States and Future Firm Performance” (Mayew & Venkatachalam, 2011) are void because the authors used an irrelevant technology (LVA technology, Nemesysco) that cannot measure emotions conveyed by voice and therefore does not produce valid results. The paper explains why LVA technology cannot work for this problem and suggests that subscribing to this methodology damages the reputation of finance and banking research. The authors are encouraged to reanalyze their speech materials using appropriate scientific methods to measure meaningful acoustic correlates of emotions conveyed by speakers’ voices.
