The present study focuses on differences in vibrato acoustics and in singer’s formant as analyzed by a novel software tool, named BioVoice, based on robust high-resolution and adaptive techniques that have proven its validity on synthetic voice signals. A specific sustained note was extracted for detailed vibrato analysis. Beside rate (s_1) and extent (cents), duration (seconds) and regularity were computed. Two new concepts are introduced: vibrato jitter and vibrato shimmer, by analogy with the traditional jitter and shimmer of voice signals. For the singer’s formant, on the same sustained tone, the ratio of the acoustic energy in formants 1–2 to the energy in formants 3, 4, and 5 was automatically computed, providing a quality ratio (QR). Some vibrato characteristics (extent, regularity, and duration) very clearly differentiate the Western operatic singing style from the jazz singing style. The singer’s formant is typical of male operatic singers. The new software tool is well suited to provide useful feedback in a pedagogical context

Abstract

The present study focuses on differences in vibrato acoustics and in singer’s formant as analyzed by a novel software tool, named BioVoice, based on robust high-resolution and adaptive techniques that have proven its validity on synthetic voice signals. A specific sustained note was extracted for detailed vibrato analysis. Beside rate (s_1) and extent (cents), duration (seconds) and regularity were computed. Two new concepts are introduced: vibrato jitter and vibrato shimmer, by analogy with the traditional jitter and shimmer of voice signals. For the singer’s formant, on the same sustained tone, the ratio of the acoustic energy in formants 1–2 to the energy in formants 3, 4, and 5 was automatically computed, providing a quality ratio (QR). Some vibrato characteristics (extent, regularity, and duration) very clearly differentiate the Western operatic singing style from the jazz singing style. The singer’s formant is typical of male operatic singers. The new software tool is well suited to provide useful feedback in a pedagogical context
