The professionalism of the Voice is the ability to control the human voice in order to activate and use it with all its expressive and influential capabilities. Voice control means learning it through analysis and theoretical and scientific analysis, and then installing it with the desired or proposed template from the student and analyst to give him the best cases in expression. This means submission to the state of training and practice of human voice with all its various data and points of performance, and, thus, the establishment of a methodology and schedule suitable for a professional purpose, scientifically applied (Scientifique – pratique) or inborn (Naturel – experimental). The former shortens the time devoted to professionalism, while the latter takes longer to increase productivity and remains free from the analysis and science that the former includes. Academic experience today has confirmed that each scientific phenomenon creates its own science and knowledge and becomes open for teaching at the university and specializes in its work and professionalism. And when knowledge precedes what is known about it, it reduces time and reduces the difficulties of confrontation. Therefore, the professionalism of its first type (scientific and applied) became the prerogative of science, its institutes and universities, without discarding the second type (innate – experienced). The two together is the best goal, and if we prefer between them, then our choice is based on the first according to scientific preference.
