Seeing and hearing the evidence

Analyses with VoceVista

Analyses of the voce faringea and further register mechanisms using the VoceVista system, with the audio examples belonging to the figures of the dissertation. Spectrogram and electroglottogram make visible what the ear hears — listen and compare for yourself.

For the methodology and full discussion, see the study Investigations of the Voce Faringea Using the VoceVista pro System (PDF).

Further EGG and audio examples

The following examples document the characteristic differences between the countertenor falsetto and the voce faringea — above all the distinctive knee in the EGG curve and the sound-pressure gain in the region of the singer’s formant cluster.

Power spectra with the indicated regions of formants 1 and 2, and EGG signal curves with a pronounced knee shape

Comparison of EGG curve shape and sound pressure level between countertenor falsetto below and voce faringea above on B4
Plate VIIIDevelopment from countertenor falsetto (below) into the voce faringea (above) on B4 — clear differences in the EGG curve shape and in the sound-pressure level within the singer’s formant cluster.
Falsetto → voce faringea · B4
Comparison of EGG curve shape and level of the third harmonic between countertenor falsetto below and voce faringea above on C sharp 5
Plate IXDevelopment from countertenor falsetto (below) into the voce faringea (above) on C♯5 — clear differences in the EGG curve shape and in the level of the third harmonic.

EGG curve of a diminuendo sung in voce faringea on B4, the knee shape persisting into the pianissimo
Plate XDiminuendo in voce faringea on B4 — the knee in the EGG curve persists even in pianissimo; the closed quotient remains constant. Dynamic gradation without loss of the register mechanism.
