Voice Kazoo


Kazoo is an exercise of a series of SOVT exercises, namely Semi-Occluded Vocal Tract. These exercises maximize the interaction between the sound source (vocal fold vibration) and the attachment (speech tract), resulting in more efficient and less taxing phonation.

Because the outflow of air/sound is impeded (by constriction/stretching or extra vibration), a backward pressure is created, making the vocal folds close more easily and with less muscle tension. The posterior pressure reduces the subglottic pressure needed to achieve vocal fold vibration, resulting in a less powerful adduction.
