Speech sounds are produced when the organs of articulation perform a complex set of movements. We correctly pronounce the different sounds as separately so in the speech flow due to the strength, good mobility and differentiated work of the organs of articulation. Thus, pronunciation of the sounds of speech is a complex motor skill.
Already in infancy a baby performs lots of different articulation and mimic movements with the tongue, lips, jaw, accompanying these movements with diffuse sounds (babbling). Such movements are the first stage in the child’s speech development; they exercise the speech organs in natural living conditions. Accuracy, power, and differentiation of these movements are developing gradually in the child.
