Perceptual Speaker Identification Using Monosyllabic Stimuli- Effects of the Nucleus Vowels and Speaker Characteristics Contained in Nasals-

The goal of our research is to find out the acoustical correlates of human perception of speaker identity. In this study we investigated the effects of the stimulus contents on perceptual speaker identification. Forty-eight monosyllables were used as the stimuli for identifying four male speakers. The results showed that the syllables containing a coronal nasal yielded higher identification accuracies than the syllables without it, and the syllables with a back vowel gained significantly better scores than those with a front vowel. We also found speaker-dependent characteristics in the velar movements in articulation of nasal consonants.
