When vocalizing into a tube on the PocketVox, no air leak is allowed during vocal exercise. Air leakage is a loss of energy, which, in turn, decreases the effects of the back-pressure. In this sense, lips are tightly pursed around the tube, but this may create hyperfunction in the tongue, jaw, and upper laryngeal muscles.
The mouthpiece has been devised in order to keep the lips relaxed and prevent unnecessary contractions of the tongue, jaw, and larynx. It is compatible with the PocketVOX.
The non-BPA silicone mouthpiece can be placed between the lips or between upper and lower teeth. In this way, the user can slightly touch the device without biting and narrowing the inlet tube to encourage further relaxation of the tongue, jaw, and larynx.
