Write about Phonology and Phonetics


Each and every language had its own unique sound and sound sequences. However, the number of possible sound distinctions which can be made in any language in quite limited. When we listen to any speakers, we can realize that they have a distinct set of sounds and certain ways to put the sounds together. So all languages share at least some sets of sounds.

Phonology is a branch of linguistics which studies the sound systems of a particular language. The word phonology is derived from Greek word “phone” which means sound and logos which means science or knowledge.

It is just one of several aspects of language which is related to other aspects such as phonetics, morphology. It is the study of how sounds are organized and sound in natural languages and description of the systems and patterns of language.

The aim of phonology is to demonstrate the pattern of distinctive sound found in a language and to make general statements as possible about the nature of sound systems in the language of the world. It is concerned with the range and function of sounds in specific languages and with the rules which can be written to show the types of phonetic relationships that relate and contrast words and other linguistic units.

Phonology is the basis for further work in Morphology, syntax, discourse and orthography design. Therefore, it analyzes the sound pattern of a language by determining which phonetic sounds are significant and explaining how these sounds are interpreted by native speakers. It studies the speech sounds only within the limited context or systems of a certain language. It is concerned only with distinctive sounds that can make differences in meaning within a language. Such distinctive sounds which become meaningful units in larger units in a given language are phonemes. It is the smallest distinctive unit in phonology of language systems, another being syntax and yet another semantics which draws upon the finding of phonetics but it doesn’t deal with the phonic medium as such.

Then it seeks to discern the sounds made in all human languages. The identification of universal and non-universal qualities of sounds is a crucial component in phonology as all languages use syllables and forms of vowels and consonants. 
Syllables are involved in the timing space of speaker language since speaking each word takes a position of time. Syllables are units of measurement in language. Vowels allow air to escape from the mouth and nose unblocked while consonants create more covering of the vocal tract by the tongue. The heard friction i.e. a consonant is made from the air that can not escape as the mouth utters the consonant.

Phonemes are units of sound are a language that conveys meaning. For instance, changing a syllable in a word will change its meaning such as changing the “a” in “mad” to an “o” to produce “mod”.

A phone can also achieve no meaning by creating non-existent. Word such as by changing the “m” in “mad” or “mod” to a “j” to produce “sad” or “jod”. Phonemes differ from morphemes and graphemes. A morpheme refers to main grammar units while grapheme is the main unit of written language.

The proper pronunciation used in a language is a practical application of phonology. For example:- Phonology uses symbols to differentiate the sounds of a particular vowel.

Vowels are classified into ‘front’ ‘central’ and ‘back’ depending on the positioning of the jaw and tongue when the vowel sounds are made.
 Phonology also note lip position such as if the lips are spread out or rounded as well as if the vowel sound is long or short. The symbol for the vowel sound in words such as ‘chilly’ or ‘fin’ in phonology is /I/ and refers to a front short vowel spoken with a tongue in high position and spread lips.

Contrasting the symbol for the vowel sound in words such as “moon” or “blue” in phonology is /u/ and refers to a back, long vowel spoken with a tongue in high position still, but with sounded lips.
                                                                Phonetics
Phonetics is derived from Greek word ‘phone’ means “sound, voice”, is the science which studies the characteristics of human sound making especially those sounds used in speech and provides methods for their description, classification and transcription of all speech sounds of human beings. It comprises the study of the sounds of human speech and is concerned with the physical properties of speech sounds (phones), and the processes of their physiology production, auditory reception and neurophysiological perception.

Thus phonetics is the study of the production, perception and transmission of speech sounds of human language in general. Phonetics deals with the ways speech sounds of human languages are produced the physical properties of transmission and the conditions of their perception.

In fact, phonetics is the basis for phonological analysis which analyzes the production of all human speech sounds regardless of language. It is the study of the phonic medium. Phonetics is categorizes into three branches which are given as below:-
1.     Articulator Phonetics: - It is the study of the way speech sounds are made or articulated by the vocal organs. It investigates and classifies speech-sounds in terms of the way they are produced by the speech organs. Thus it is concerned with the articulation of speech. The position, shape, and movement of articulators or speech organs, such as the lips, tongue, and vocal folds.  
2.     Acoustic phonetic: - It studies the physical properties of speech sound as transmitted between mouth and ear. In terms of the physical properties of the sound waves that are created by the activity of the speech organs and travel through the air from speaker to hearer. It is concerned with acoustics of speech: The properties of the sound, waves, such as their frequency and harmonics.
3.     Auditory phonetics: - It studies the perceptual response to speech sounds, as mediated by ear; auditory nerve and brain. In terms of the way the speech sounds are perceived and identified by the listener’s ear and brain. So it is concerned with speech perception. How sound is received by the inner ear and perceived by brain.
 
Phonetics is the criterion with which we operate in the phonological analysis of languages. It is the study of the articulatory and acoustic properties of the sounds of human language. 
In contrast to phonetics, phonology,is the study of language-specific systems and patterns of sound and gesture, relating such concerns with other levels and aspects of language. While phonology is grounded in phonetics, it has emerged as a distinct area of linguistics, dealing with abstract systems of sounds and gestural units (e.g, phoneme, features, mora, etc.) and their variants e.g., allophones, the distinctive properties  which form the basis of meaningful contrast between these units, and their classification into natural classes based on shared behavior and phonological processes. Phonetics tends to deal more with the physical properties of sounds and the physiological aspects of speech production and perception. It deals less with how sounds are patterned to encode meaning in language (though overlap in theorizing, research and clinical applications are possible.
