pocketVOX Voice Therapy and Vocal Training Tool is made of high-quality silicone and by its ergonomic design, it can fit easily most of 50 cl. pet water bottles and the specially designed cello bottle for pocketVOX.
pocketVOX Voice Therapy and Vocal Training Tool uses the mechanisms of DoctorVox Voice Therapy Technique for voice therapy and professional voice development. The main mechanism involves artificial elongation of the vocal tract and a secondary vibrating resistance (i.e. water bubbles) for vocal tract inertance. It is designed for practical daily use for rehabilitation of dysphonic patients and habilitation of professional voice users.
There are two tube openings on the top. One of the tubes is for the breathing outlet from humidification. The other one which the user can (phonate) blow voice into water.
In order to control the active backpressure, the user can adjust T-Valve on pocketVOX.
