The effects of vocal variation on listener recall.
The effects of variations in speaker rate and pitch on listener recall were studied. One hundred and twenty participants listened to an audiotape of one of two individuals speaking in one of four different styles--low variation in both rate and pitch, variation in rate but not in pitch, variation in pitch but not in rate, and variation in both rate and pitch. After hearing the audiotape, listeners were tested on the information in the presentation; they also completed questionnaires rating the speaker's benevolence and competence. Results indicated that the combined effect of pitch and rate variety significantly increased listener recall over no variety or pitch variety increased attributions of speaker competence over no variety or rate variety or rate variety alone. Additionally, pitch variety and combined pitch and rate variety significantly increased attributions of speaker competence over no variety or rate variety alone, but significantly decreased attributions of speaker benevolence.
