A self-sustained vocal-ventricular phonation mode: acoustical, aerodynamic and glottographic evidences

Leonardo Fuks, Britta Hammarberg, Johan Sundberg
Publication date
This investigation describes various characteristics of a particular phonation mode, vocal-ventricular mode (VVM), as produced by a healthy, musically-trained subject. This phonation mode was judged as perceptually identical to that used in the Tibetan chant tradition. VVM covered a range close to an octave, starting at about 50 Hz. High-speed glottography revealed that the ventricular folds oscillated at half the frequency of the vocal folds thus yielding a frequency of f/2. Phonation at f/3 was also possible. Presumably, aerodynamic forces produced by the glottal flow pulses sustained the vibrations of the ventricular folds. Complementary aspects of this type of phonation were compared to phonation in modal and pulse registers by acoustical analysis of the audio signal, by inverse filtering of the flow signal and by electroglottography (EGG). In addition, oesophageal pressures were measured. These analyses …

Dans cet atelier (en anglais), Johan Sundberg présente une revue de ses recherches menées sur la technique vocale des chanteurs. The talk presents examples of investigations which have aimed at understanding the vocal technique of singers. The relevance of voice research to vocal pedagogy is discussed in the light of examples of alternative facts that are still surviving among some teachers of singing. A variety of studies of the singing voice are reviewed and the advantage of analysing singers’ as opposed to untrained voices’ vocal characteristics will be discussed. Also some studies of aesthetical and expressive aspects of singing are discussed.

Perceptual aspects of singing*



The relations between acoustic and perceived characteristics ofvowel sounds are demonstrated with respect to timbre, loudness, pitch, and expressive time patterns. The conditions for perceiving an ensemble of sine tones as one tone or several tones are reviewed. There are two aspects of timbre of voice sounds: vowel quality and voice quality. Although vowel quality depends mainly on the frequencies of the lowest two formants, voice quality depends mainly on the frequencies of the higher formants. In particular, the center frequency of the so-called singer’s formant seems perceptually relevant. Vocal loudness, generally assumed to correspond closely to the sound pressure level, depends rather on the amplitude balance between the lower and the higher spectrum partials. The perceived pitch corresponds to the fundamental frequency, or for vibrato tones, the mean of this frequency. In rapid passages, such as coloratura singing, special patterns are used. Pitch and duration differences are categorically perceived in music. This means that small variations in tuning or duration do not affect the musical interval and the note value perceived. Categorical perception is used extensively in music performance for the purpose of musical expression because without violating the score, the singer may sharpen or flatten and lengthen or shorten the tones, thereby creating musical expression.
