Abstract

Utterances of two adults males were analyzed and synthesized by a fast Fourier Transforms method. Each of the two voices was synthesized in each of the twenty‐seven combinations of three levels each of rate, mean , and variance of (a total of fifty‐four “voices” generated from two). The effects of the rate, mean , and variance of manipulations, the interactive effects of rate and variance of , and the effects due to speaker were all statistically significant predictors of personality ratings given the voices. They accounted for 86%, 4%, 3%, 2%, and I% of the variance, respectively, in competence ratings and 48%, 1%, 6%, 1%, and 8% of the variance, respectively, in benevolence ratings. Increased speaking rate was found to decrease the benevolence ratings, and decreased rate was found to decrease competence ratings. Decreased variance of was found to decrease the ratings on both competence and benevolence. Increased mean in these male voices was also found to decrease competence and benevolence ratings.
