A study of relationship between speaker identification and acoustic features using perceptual similarity of imitated voice

摘要

Physical correlates of perceived personal identity are investigated using imitated 16 utterances spoken by 11 mimicry speakers and 24 test subjects. Our unique strategy to use non-professional impersonators enabled to prepare test utterances with wide range of perceived similarities. Reasonably high correlations (0.46 and 0.44) in multiple regression analysis were attained by grouping subjects into three groups based on cluster analysis of the subjective test results. Without clustering, the correlation was only 0.17. The cluster analysis also revealed differences in their focusing physical correlates between three groups indicating importance of individual differences both in speakers and listeners.
