Voice Production Mechanisms of Vibrato in Noh
نویسندگان
چکیده
Vibrato used in Noh play was investigated using electroglottographic and acoustical analyses. Laryngeal movements were successfully obtained from the EGG signal and its derivative in order to study how the peculiar and expressive voice qualities were produced during vibrato. The slow wide vibrato of Noh was achieved not only by the F0 modulation but also by changing the degree of constriction at the vocal folds and the supraglottal structures. These complicated movements at the end of the resonator seemed to add color and variety to the voice quality, and produce an extremely unique vibrato.

Singing Voice Synthesis: Singer-Dependent Vibrato Modeling and Coherent Processing of Spectral Envelope
Pleasant singing voice is often ornamented by vibrato. This pitch fluctuation acts as a distinctive feature for singing and promotes voice quality. Nevertheless, independent pitch processing in singing voice synthesis does not guarantee the output quality. The spectral envelope actually varies with pitch during human voice production. This paper proposes a modeling technique for singers’ vibrat...

The application of inverse filtering techniques for high-quality singing voice analysis/synthesis is discussed. In the context of source-filter models, inverse filtering provides a noninvasive method to extract the voice source, and thus to study voice quality. Although this approach is widely used in speech synthesis, this is not the case in singing voice. Several studies have proved that inve...

Vibrato is one of the most expressive aesthetic characteristics of singing voice. Indicative of good voice quality is typical of lyrical singing but it is also found in others styles of popular music. Acoustically, vibrato is defined as a long-term periodic modulation of the fundamental frequency. It occurs as a result of the laryngeal muscular system and is comprised of 3 main parameters: rate...
