Voice projection

Voice projection is the strength of speaking or singing whereby the voice is used loudly and clearly. It is a technique employed to command respect and attention, as when a teacher talks to a class, or simply to be heard clearly, as used by an actor in a theatre.

Breath technique is essential for proper voice projection. Whereas in normal talking one may use air from the top of the lungs, a properly projected voice uses air properly flowing from the expansion of the diaphragm. In good vocal technique, well-balanced respiration is especially important to maintaining vocal projection. The goal is to isolate and relax the muscles controlling the vocal folds, so that they are unimpaired by tension. The external intercostal muscles are used only to enlarge the chest cavity, whilst the counterplay between the diaphragm and abdominal muscles is trained to control airflow.
