Course Details

Several types of SOVTE have been used and described in both voice rehabilitation and voice training.

The water resistance therapy (WRT) method (a type of SOVTE) consists of phonating different phonatory tasks into a glass tube, keeping the distal end of the tube submerged in water. Research on WRT has suggested the presence of a massage-like effect on vocal folds and vocal tract tissues, and changes in aerodynamic measures, electroglottographic (EGG) contact quotient (CQ), and vocal tract configuration.

These effects are assumed to contribute to vocal economy. Poral modulation during water bubbling has been established at a frequency of 12-40 Hz. The magnitude of variation of Poral during tube phonation in water has also been examined. Several practical variables affect water bubbling during WRT and they should be controlled when using this exercise for voice training.

The present course was designed to provide information about the variables that need to be controlled during WRT based on research findings. Practical demonstrations on how to properly performs WRT are also considered.
