The role of the formant intensity in the analysis of emotionally sung vowels

Abstract

The formant intensity could reflect the emotional energy involved in singing. A spectrographic analysis of emotionally sung vowels [a] and [i] is used to investigate this hypothesis. The emotional effects on the formant intensity of the vowel [a] of a tenor, [i] of a bass and alto, and [i] of male and female singers are presented. The results show the emotional difference among individual singers as well as between groups of singers. The emotivity, defined as the ratio of the emotional and neutral formant intensities, of a bass is compared to that of an alto
