On the use of straws and tubes in vocal exercising. In vivo measurements of air pressure characteristics of phonation into a straw and a resonance tube in air and in water

Popis výsledku v původním jazyce

Three most widely used methods in voice training and therapy were investigated from the point of view of phonation threshold pressure PTP as well as electroglottographic parameters for the most comfortable phonation at habitual speaking pitch. The methods were: Phonation into a glass resonance tube in the air, the outer end submerged below water surface and phonation into a narrow straw. Compared to vowel phonation /u:/, phonation into resonance tube in air gave the lowest PTP and tube 10 cm under waterthe highest. Oral pressure was lower for tube in air than for vowel /u:/. Oral pressure oscillation was highest for tube 10 cm in water, which may offer massage effect on the vocal tract and vocal folds. Transglottal pressure was larger for all exercises, being largest in those exercises which offer highest supraglottic impedance. In EGG signal the CQ was higher for the tubes compared to vowel phonation. The largest change was observed for tube 10 cm in water.
