The importance of vocal self-regulation

The human voice is extremely flexible and adjustments of quality, frequency, and intensity serve to signal various moods, emotions, and intentions. These modifications occur automatically in daily life, but can also be implemented in a developed, controlled, and consciously applied way, in spoken and sung artistic expression. The vocal output depends on a series of anatomical, physiological, and neurological factors, however, there is a crucial participation of the emotional component that impacts the vocal output.
