Effects of stimulus contents and speaker familiarity on perceptual speaker identification

Abstract

In this study, we conducted a perceptual speaker identification experiment in order to examine the effects of speaker-listener familiarity and of the stimulus content. We used the same materials as those used in our previous study [6], where familiar listeners identified the speakers. The results showed that familiar listeners performed significantly better than naive listeners; however, the overall effects of the stimulus content were similar between familiar and naive listeners. The nasals /na/ and /nja/ were particularly effective for speaker identification, and the identification score differences among the coronal nasals and the labial nasal was again observed in this study. © 2007 The Acoustical Society of Japan.
