The vowel quadrilateral is a rough sketch of the inside of
the oral cavity. As can be noted, the right axis is at a 90-degree angle,
whereas the left axis is at a much wider angle. Think about this in
relationship to the mouth and tongue. What implications do these differences
have in relationship to vowel production and the movement capabilities of the
front versus the back of the tongue? If you work with a child who has vowel
difficulties, how could you use this information clinically?
