Articulatory Phonetics

The oldest and best established of these is know as articulatory phonetics. It is based on the assumption that the characteristics of talk hold outs are the results of their modes of formation. They may accordingly be described and sensitive by stating the position and action of the various speech organs. This physiological approach has been one of the basic tools of linguistics for many historic period and has proved very productive" (Gleason, 1955, p. 20). Nevertheless, the great variations in pronunciation from dialect to dialect have proved beyond the backdrop of articulatory phonetics by itself. So has the fact that the human weapon can produce an infinity of sounds.

Close attention to twain phonetic quality and distribution generally provides accurate appellation of the vowel phonemes and compound nuclei. Speech production is an incidental action at law of the respiratory system. Most of the time, air passes into and out of the lungs more or less silently; only when there is some obstruction is appreciable sound produced. Speech further requires that there be easy and effective control of these sound-producing obstructions. This limits the mechanisms of interest to linguists largely to movements inwardly the mouth, pharynx, and larynx. Yet, the motive power for sound production arises largely in the activity of the thorax which, therefore, has an important, though rather different, effect on speech production. Traditionally, phonetics classifies speech sounds into 1)the act

The study division in speech sounds is that between vowels and consonants. Phoneticians have put in it difficult to give a precise definition of the articulatory distinction between these two classes of sound. Most authorities would add that a vowel is a sound that is produced without any major(ip) constrictions in the vocal tract, so that there is a relatively free passage for the air. It is also syllabic. This description is unsatisfactory in that no adequate definition of the native syllabic has to date been formulated (The New Encyclop?dia Britannica, 1974).

All speech consists of a sequence of syllables and breath-groups, which are phonetically the basic framework of speech, and the most all the way detectable segmentation.

"Their phonemic status is, however, another matter" (Gleason, 1955, p. 204.

The coarse majority of speech sounds are stops, fricatives, or resonants. Any sound is modified by the shape of the air passages and cavities open to it. Thus, if section is produced by the vocal cords, the sound will be quite different depending on whether the unwritten passage, the nasal passage, or both are open to it as allowed by the shape of the oral passage.

Phonetically, speech is always something more than a linear while of sounds. Since these are mostly produced by air expelled from the lungs, the respiratory machine in the thorax necessarily breaks the sequence into portions. The most demonstrable of these is the breadth-group. This is the chain of sounds produced on one breath. Its maximum duration is controlled by the necessity of periodic inhalation. A breath-group does not, however, necessarily last as long as the air contained in the lungs might allow.
