Electroglottographic Study of Seven Semi-Occluded Exercises: LaxVox, Straw, Lip-Trill, Tongue-Trill, Humming, Hand-Over-Mouth, and Tongue-Trill Combined With Hand-Over-Mouth
Original language description
Introduction. Semi-occluded vocal tract exercises (SOVTE) are often used in voice clinics. SOVTE change the acoustic vocal tract impedance in relation to the glottis impedance, improving voice quality. However, differences among SOVTE, such as the numberof vibration sources into the vocal tract, are often disregarded by clinicians. Some SOVTE present single, whereas others double source. This study aims at investigating changes in voice production pattern for a series of SOVTE. A combined exercise (tongue-trill coupled with hand-over-mouth) was implemented to illustrate the effect of a secondary source of vibration in the vocal tract. Method. Twenty-three healthy volunteers performed a series of SOVTE: LaxVox, straw, lip-trill, tongue-trill, hand-over-mouth, humming, and tongue-trill combined with hand-over-mouth. Comfortable phonation served as control exercise. The dependent variables were electroglottography contact quotient (CQ), contact quotient range (CQr), fundamental frequency
