Characterizing vocal-fold dynamics in singing vocal modes from Complete Vocal Technique using high-speed laryngeal imaging and electroglottographic analysis (original) (raw)

Complete Vocal Technique (CVT) is a method used in voice pedagogy. In CVT, all voiced sounds (with vowels) are divided into four vocal modes – Neutral, Curbing, Overdrive and Edge. The vocal modes are identified and defined according to auditory attributes - metal, density, vowel and loudness – setting practical rules for the use of vocal modes. Recent laryngostroboscopic imaging studies have demonstrated visibly different laryngeal gestures between Curbing, Overdrive and Edge (McGlashan et al., 2016; Thuesen et al., 2017; Aaen et al., 2018). There are no study on vocal-fold dynamics of the vocal modes using high-speed imaging. The aim was to examine vocal-fold dynamics in CVT four vocal modes by means of laryngeal imaging techniques and electroglottography (EGG) analyses. Furthermore, the purpose was to test the feasibility of the selected methods to assess CVT vocal modes. Five non-classical singers (3 F mean age 38 yo; 2 M mean age 41 yo) trained in CVT were imaged with highspeed...
