Here you see the videoclips of effects used in songs. The videos are taken using a flexible endoscope inserted via the nose. Stroboscopic light is used so the vibration of the vocal folds can be seen in slow motion. The flashing of the stroboscopic light is triggered using the Laryngograph signal. This is obtained by placing two electrodes placed on the neck over the larynx and the waveform can be seen as a a green moving line at the bottom of the image. When the vocal folds are vibrating and touch each other the green line rises and when they peel apart the line falls creating the change in shape of the waveform.
Again notice the patterns in the visual recognizion of the laryngeal gestures and the EGG waveforms.

This information comes from a study effects with the title ‘Can vocal effects such as distortion, growling, rattle and grunting and be produced without traumatising the vocal folds?’. This study was presented by Julian McGlashan at PEVOC7 conference in Groningen, Netherlands, 2007.
This study with the title ‘Analysis of the mechanism of effects such as Distortion, Growl, Grunt and Rattle used in a healthy way by 18 professional singers’. was presented by Cathrine Sadolin at Pevoc 10 (Pan-European Voice Conference) Prague, Czeck Republic, August, 2013.
