This study explored speaker idiosyncrasy by measuring the syllabic intensity variability in the speech signal. Sixteen speakers of the TEVOID corpus, each producing 256 read sentences, were analyzed. Characteristics of intensity variability (average or peak) between syllables were measured either holistically (standard deviation of intensity changes between syllables) or locally (pairwise variability indices of intensity changes between syllables). The results indicated significant effects of the speakers in all the metrics, suggesting a potential application of the methods for speaker recognition, and in particular for forensic speaker comparison.
