This paper reconfirms that talker identity can be transmitted across languages. Talker discrimination was examined in the ABX paradigm, where the stimuli A and B were utterances by different talkers in the same language and the stimulus X was an utterance by either of A or B in the different language. The average hit rate of this discrimination task was as high as 0.89. The mutual distance matrices were generated using the discrimination index, ′ d . By applying the multidimensional scaling, three-dimensional perceptual spaces were estimated. The features related with loudness and spectral centroid had high contribution to the perceptual dimensions. Index Terms: talker discrimination, bilingual corpus, MDS, auditory model
