title: Increased pitch increases accuracy of voice identification.
abstract: Previous work suggested that greater accuracy rates in identifying voices that have been increased in frequency over those that have been decreased in frequency may be due to complex vocal characteristics and specific memory for familiar voices. Here we asked 17 men and 21 women between the ages of 18 and 21 to learn a simple vowel exemplar produced by an unfamiliar target speaker and measured the proportion of times the frequency-shifted exemplar was identified as the originally encoded target speaker. Analysis showed that exemplars when increased in frequency were perceived as belonging to the target speaker significantly more often than exemplars which were decreased in frequency. These findings suggest that the greater accuracy in identifying speakers with increased frequency voice samples does not require previous familiarity with the vocalizations of a particular speaker or complex memory schemata for familiar voices.
