Effects of linguistic contents on perceptual speaker identification:Comparison of familiar and unknown speaker identifications~1

摘要

There are several factors that affect human speaker recognition. In this study, twoexperiments were conducted in order to see the effects that the stimulus contents and the familiarity tothe speakers give to the perception of the speakers. The results showed that: a) stimuli including anasal were effective for accurate speaker identification; b) coronal nasals were more effective than thelabial nasal, and c) the familiarity to the speakers gives a great influence on the performance. Thetendencies a) and b) were observed both in familiar and unknown speaker identifications. The resultsof the acoustical analyses also showed that there were correspondences between the perception of thespeaker identity and the cepstral distances among the speakers. The inter-speaker cepstral distanceswere greater in vowel intervals than in the consonant intervals; especially, notably they were greater innasals than in orals in the consonant intervals
