Capacity that people develop gradually from the earliest years of life through sounds that can be organized to give meaning to what you want to express and provide a coherent meaning. This involves four processes: conceptualization, formulation, articulation and self-control. The first requires content planning, ie thematic knowledge. The second finds words and phrases to give meanings and preparation before pronunciation. The third is the control of articulatory organs like lips, tongue, teeth, alveolar palate, veil, glottis, buccal cavity and breath and finally self-control is concerned with correcting errors.

It is important to encourage interaction for oral practice in physical and virtual environments that allow the development of this ability for the purpose of integration of precision, complexity and fluency.
