Semioclouded Vocal Tract Exercises cup – Pró-Phono ETVSO
14,90 € (VAT not included)
Bottle for balancing glottal pressures, relaxing the CCVV and improving phonation
The “ETVSO Pro-Phono Bottle: Semi-occluded Vocal Tract Exercises” allows to perform expiratory exercises, with or without phonation.
- The bubbling of the water during phonation with the tube submerged generates retroreflex energy that acts as a massager of the vocal cords.
- From the constriction of the vocal tractand these consequent vibratory sensations, laryngeal and supralaryngeal adjustments and a more balanced vocal emission at the level of pressures are made possible.
- The device consists of: plastic container or bottle graduated in milliliters, a plastic bottle cap with two internal holes (one for the silicone tubing to enter and one for the air to exit),a non-toxic medical gradesilicone tube measuring 35 cm long, 9 mm internal diameter and 13 mm external diameter,six plastic air flow pressure regulators (levels 1 to 6).
- This device is recommended when it is desired to promote adjustments of the glottic and laryngeal muscles; expand the vocal tract; improve voice resonance (increasing the oral component of this resonance), facilitate pneumophonic coordination; etc.
Suggested exercises are available in the Instruction Manual. For more information, please refer to the long product description.

Bottle for semi-occluded vocal tract exercises
The device “Pró-Fono ETVSO Bottle: Semi-occluded vocal tract exercises” is the result of a new collaboration between researchers and the Pró-Fono industry.
It was developed to perform expiratory exercises, with or without phonation, with pressure increase in expiratory airflow. When the exercises are associated with phonation, the infraglottic pressure required for its initiation is reduced (Figure 1).
Figure 1. Supraglottic positive pressure increased with the use of the ETVSO Pro-Fono bottle: semi-occluded vocal tract exercises.

In addition, the bubbling of the water during phonation with the tube submerged generates retroflex energy which acts as a massager of the vocal folds. From the constriction of the vocal tract and these consequent vibratory sensations, laryngeal and supralaryngeal adjustments and a more balanced vocal emission at the level of pressures are made possible.
The device consists of:
- A plastic container or bottle graduated in milliliters to control the amount of water inserted (100 to 400 ml) and in centimeters to control the immersion depth of the tube;
- A plastic bottle cap with two internal holes (one for the silicone tube to enter and one for the air to escape);
- A non-toxic medical grade silicone tube measuring 35 cm long, 9 mm internal diameter and 13 mm external diameter;
- Six plastic air flow pressure regulators (levels 1 to 6), with air flow passage orifices of 4.5 mm, 4 mm, 3.5 mm, 3 mm, 3 mm, 2.5 mm and 2 mm in diameter (levels 1 to 6 respectively) (Figure 2).

How to use
ETVSO Pro-Phono Bottle Differential – control of the muscular effort used in the performance of semi-occluded vocal tract exercises, obtained by different combinations of the amount of water in the Bottle (100 to 400 ml), the selection of the level of the air flow regulator (levels 1 to 6) and definition of the immersion depth of the tube in water (0cm to 10cm).
Suggested exercises are available in the Instruction Manual.
Indications
Phonation exercises with this device are recommended when desired:
- To favor the adjustment of the glottic and laryngeal muscles;
- Promote adequate glottal coaptation;
- Expand the vocal tract;
- Reduce supraglottic involvement in phonation;
- Stimulate the elevation of the soft palate;
- Improve the resonance of the voice (increasing the oral component of this resonance).
- To provide better pneumophonic coordination;
- Improve kinesthetic feedback during phonation;
- Develop the monitoring of vocal emissions.
PróFono instruments by area of work
Within the electrostimulation category, PróFono is the home of the consumables and accessories. The conductive pen extender reaches specific points, the Stim care is the range's portable neuromuscular electrostimulator, and the facial mask with extraoral electrodes lets you treat several muscle groups at once. For resisted exercise, PróFono makes a family of exercisers with different loads: the facial exerciser for the perioral muscles, the tongue exerciser and the lip exerciser. The haltere-style lingual weights let you increase load gradually, which is hard to achieve with isolated oral praxis.Voice and aerodynamics
In voice and aerodynamics, the semi-occluded vocal tract exercise cup (SOVTE) applies the tube-in-water principle with stable depth control, and the Scape-scope makes nasal escape visible in hypernasality, useful when the patient cannot hear their own error.Why buy PróFono at Logopedicum?
