This device is easy to carry and is safe to be used anywhere. It is intended to assist voice therapy and to serve as a supporting device for professional voice users. pocketVOX is designed to help to motor learning and cognitive processes involved in voice therapy and vocal training. pocketVOX provides instant humidification of the vocal folds. Additionally, herbal and medical products can also be used for inhalation. pocketVOX uses the mechanisms of LaxVox 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. The artificial elongation is provided by a built-in tube which is designed nearly the same length with the human vocal tract. It is designed for rehabilitation of dysphonic patients and habilitation of the professional voice users. There are two tube openings on the top. One of the tube is for the breathing outlet from any plastic water bottle. The other one which the user can (phonate) blow voice into water. The active length of the inner tube is about the same length with the human vocal tract so that standing waves form in a natural way. Maximum water height is designed to be below phonation threshold pressure. There are signs on the phonation tube of pocketVOX (this is advised by Finnish Therapist Sovijarvi and it is not scientifically proven) which are for basses and alto sopranos (indicated by: al-ba), the length of the phonation tube is 28 cm (no cuts). For baritones and mezzosopranos (indicated by: me-ba) the user can cut the tube by scissors and adjust the length for himself/herself. For sopranos and tenors (indicated by so-te) it is 26 cm; for children (indicated by ch) it is 24cm.
