articulatory system การใช้

There are two main types of sound sources in the articulatory system : periodic ( or more precisely semi-periodic ) and aperiodic.
The three pistons present in the articulatory system are the larynx, the tongue body, and the physiological structures used to manipulate lung volume ( in particular, the floor and the walls of the chest ).
Some linguists ( such as Roman Jakobson and Morris Halle ) proposed that phonemes may be further decomposable into Ladefoged's system is a purely articulatory system apart from the use of the acoustic term'sibilant '.
