Modification of structure either with or without clinical speech services. During the oral-peripheral examination, the clinician should rate the each part of the mechanism in the following three areas. This assess the anatomy of the oral-peripheral structures at rest and relative to effects on shaping the vocal tract for intelligible speech. This assess the neuromuscular systems ability to generate appropriate muscle tone and contraction to move structures for intelligible speech. These dynamics include, but are not limited to the following.
Some functions overlap, while others are specialized.
Consonants are created by valving the air stream generated in the respiratory system. The degree and location of this valving influences nature and quality of productions. Vowels and semi-vowels are produced by shaping the size and shape of the vocal tract. Intelligible speech requires the interaction of these two process. Parameters of movement that can influence quality and indelibility include the following.
