practice of using a limited vocabulary based on a word list or other source.
graded readers are often written using vocabulary control.
vocal cords n
the folds of tough, flexible tissue in the larynx extending from back to front.
The space between the vocal cords is the glottis. When the vocal cords are
pressed together, the air from the lungs is completely sealed off. During speech,
the vocal cords open and close the air passage from the lungs to the mouth.
In the production of vowels and voiced consonants (see voice^2 ) the vocal
cords vibrate.

vocal tract n
(in phonetics) the air passages which are above the vocal cords and which
are involved in the production of speech sounds.
The vocal tract can be divided into the nasal cavity, which is the air passage
within and behind the nose, and the oral cavity, which is the air passage
within the mouth and the throat.
The shape of the vocal tract can be changed, e.g. by changing the position
of the tongue or the lips. Changes in the shape of the vocal tract cause
differences in speech sounds.
