Water Resistance Therapy For Voice Training: Research Findings And Practical Demonstrations
Thursday 7th October 2021, 5:00 PM - 7:00 PM (London Time)
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.

Optimising Voice Quality through Nasal Hydration. What are the Implications for the Voice Community?

María Borragán Salcines

Carles Expósito Rovira
The vocal folds need a high degree of humidity to be able to vibrate at their normal high frequency. Hydration makes the tissue more flexible and more turgid. The moisture of the tissue is one of the first factors that is lost when there is a pathology or when an unusual overload is suffered. Voice professionals often deal with stress, anxiety, fatigue, and changes of temperature and environment like the dryness of the performing spaces, due to factors like air conditioning or heating. All these factors affect the voice and can make the performer activity more difficult!
