The phonetic system of language is a set of phonetic units arranged in an orderly way to replace each other in a given framework. Phonetics is divided into two major components (or systems): segmental phonetics, which is concerned with individual sounds (i.e. "segments" of speech) and suprasegmental phonetics dealing with the larger units of connected speech: syllables, words, phrases and texts.
1. Segmental units are sounds of speech (vowels and consonants) which form the vocalic and consonantal systems;
2. Suprasegmental, or prosodic, units are syllables, accentual (rhythmic) units, intonation groups, utterances, which form the subsystem of pitch, stress, rhythm, tempo, pauses.
Now we may define phonetics as a branch of linguistics that studies speech sounds in the broad sense, comprising segmental sounds, suprasegmental units and prosodic phenomena (pith, stress, tempo, rhythm, pauses).
Let us consider the four components of the phonetic system of language.
The first and the basic component of the phonetic structure of language is the system of its segmental phonemes existing in the material form of their allophones. The phonemic component has 3 aspects, or manifestations:
1. the system of its phonemes as discrete isolated units;
2. the distribution of the allophones of the phonemes;
3. the methods of joining speech sounds together in words and at their junction, or the methods of effecting VC, CV, CC, and VV transitions.
The second component is the syllabic structure of words. The syllabic structure has two aspects, which are inseparable from each other: syllable formation and syllable division.
The third component is the accentual structure of words as items of vocabulary (i.e. as pronounced in isolation). The accentual structure of words has three aspects: the physical (acoustic) nature of word accent; the position of the accent in disyllabic and polysyllabic words; the degrees of word accent.
The fourth component of the phonetic system is the intonational structure of utterances. The four components of the phonetic system of language (phonemic, syllabic, accentual and intonational) all constitute its pronunciation (in the broad sense of the term). Another subdivision of phonetics:
