Cued speech is a visual system of communication used with and among deaf or hard-of-hearing people. It is a phonemic-based system which makes traditionally spoken languages accessible by using a small number of handshapes, known as cues (representing consonants), in different locations near the mouth (representing vowels) to convey spoken language in a visual format.
These settings involve secondary articulation, usually in addition to any articulation that would be expected for non-pathological speech. They are called voices because they affect the sound quality of the utterance (that is, the individual's human voice ), though this usage contradicts the IPA use of the word "voice" for voicing .
Articulatory synthesis refers to computational techniques for synthesizing speech based on models of the human vocal tract and the articulation processes occurring there. The shape of the vocal tract can be controlled in a number of ways which usually involves modifying the position of the speech articulators, such as the tongue , jaw , and lips.
The point of maximum obstruction is called the place of articulation, and the way the obstruction forms and releases is the manner of articulation. For example, when making a p sound, the lips come together tightly, blocking the air momentarily and causing a buildup of air pressure. The lips then release suddenly, causing a burst of sound.

Its manner of articulation is fricative, which means it is produced by constricting air flow through a narrow channel at the place of articulation, causing turbulence. Its place of articulation is palatal , which means it is articulated with the middle or back part of the tongue raised to the hard palate .
In the vowel diagram, convenient reference points are provided for specifying tongue position. The position of the highest point of the arch of the tongue is considered to be the point of articulation of the vowel. The vertical dimension of the vowel diagram is known as vowel height, which includes high, central (mid), or low vowels.
