[Overton]Articulation: Shaping Our Speech

Because most of us are able to speak so effortlessly, we think that speaking is simple. However, our ability to speak is actually the result of many complex coordinations that take place between several different systems in our bodies.

Speech, like any other sound, requires energy (provided by air from the lungs), sound (produced by vibration of the vocal folds in the larynx) and amplification, or resonation, (accomplished as the sound travels through the chest, mouth and nose). In addition, it has to be shaped, or articulated.

Speech is articulated when the lips, jaw, tongue and soft palate move to shape the sound produced by the vocal folds into individual speech sounds. These structures can shape the sounds by:

Development of the ability to articulate speech begins in infancy and is a gradual process that continues through a child's sixth or seventh year. It requires:

Taking into consideration all that's necessary just to shape the sound produced by the vocal folds, it's not surprising that articulation disorders (the inability to correctly produce speech sounds) are so common. In fact, articulation disorders constitute approximately 32% of all communication disorders.
