Branches of Phonetics

            We have already learned that the phonetics performs three distinct but inter-dependent tasks, such as production, transmission, phonetics is divided into three branches - articulatory phonetics, acoustic phonetics and auditory phonetics. These three branches cover the study of speech sounds on the basis of concrete and  objective observation as well as scientific analysis. Let us now have more ideas of the functions of these branches.

1. Articulatory Phonetics: Articulatory phonetics deals with the way in which speech sounds are produced. To produce speech sounds, we use different speech organs or articulators - lips, teeth, tongue, soft palate, nasal passage, glottal folds, lungs, etc. Different speech organs behave in different manners to articulate speech sounds. Hence, we can classify speech sounds on the basis of our experience of the speech organs, their inter-relationships and their behaviors. All these functions and factors are dealt with in articulatory phonetics.
That is, articulatory phonetics studies speech organs as well as their movement and contact in the articulation of speech sounds, and provides us with as classification of the sounds used in a particular language and language in general. To brief, this branch of phonetics is concerned with how speech sounds are produced by which articulators.
2. Acoustic Phonetics: Acoustic phonetics deals with the speech sounds that is transmitted through the air from the speaker to the listener. The transmission of speech sounds is constituted of some physical properties, such as frequency, and amplitude resulting in sound waves. These physical properties of speech sounds are analyzed and investigated in acoustic phonetics.
3. Auditory Phonetics: Auditory phonetics deals with how speech sounds are received and perceived by the listener and to listen and realize speech sounds, he/she has to use his/her ears, auditory nerve and brain. Hence, the reception and perception of speech sounds create a complex process. This complex process is explored and analyzed in auditory phonetics.

Difference between Phonetics and Phonology

            Both phonetics and phonology are both concerned with speech sounds although they deal with different aspects of speech sounds in linguistics investigation. We would look at the distinction between phonetics and phonology.








Firstly, phonetics is a science of speech sounds, which studies their production, transmission and reception in an impartial and practical manner, even in laboratory. On the other hand, phonology is the study of the ways in which sounds form system and pattern is called phonology.


Secondly, phonetic is confined to the concrete level of sound descriptions, whereas phonology has its job within the abstract level of sound analysis.


Thirdly, a phonetic study of a language refers to the inventory and description of phonetic segments of the language. On the other hand, a phonological study of a language refers to the  inventory of phonemic segments of the language.

Fourthly, while a phonetic entity or unit is 'phone', a phonological unit is 'phoneme.' 


Fifthly, a phonetic unit is transcribed between square brackets, for example [p] etc. On the other hand, a phonological unit is transcribed between slashes, for example /p/, /t/ etc.


Sixthly, a phonetic unit is incapable of meaning contrast, while a phonological unit is can produce a meaning difference.






In sum, while phonetics is concerned with the physical properties of speech sounds, phonology studies how speech sounds function to produce meaning contrast.

Receive Pronunciation (RP) or BBC Pronunciation

            The accent that we concentrate on and use as our model is the one that is most often recommended for foreign learners studying British English. It is for a long time been identified by the name 'Receive Pronunciation (RP).'




Receive pronunciation (RP), the term suggesting that is result of social judgement rather than of an official decision as to what is correct or wrong. It has become more widely known and accepted through the advant of radio television. The BBC used to recommend this form of pronunciation for its announcers and news readers mainly because it was the type which was most widely understood and which excited least prejudice of a regional kind. Thus, receive pronunciation (RP) often became identified in the public mind with 'BBC English.' This special position occupied by 'Receive Pronunciation (RP)', basically educated southern British English and traditionally taught to foreigners.

Phonetic Transcription

                                                                         

             Phonetic transcription is a system for transcribing sounds that occur in spoken language or signed language. The most widely known system of phonetic transcription, the International Phonetic Alphabet (IPA), uses a one-to-one mapping between phones and written symbols. The standardized nature of the IPA enables its users to transcribe accurately and consistently the phones of different languages, dialects, and idiolect. The IPA is a useful tool not only for the study of phonetics, but also for language teaching, professional acting, and speech pathology.

What is Phonology?

     The word phonology derived from two Greek words. The first one is phone means 'voice, sound.' The second one is logos means 'word, speech, subject of discussion.' So we can say, the study of the ways in which speech sounds from system and pattern is called phonology.

                                                                       

The term phonology, like grammar, is used in two ways: as the mental representation of linguistic knowledge and as the description of this knowledge. If phonetics can be linked to a world, phonology is a country. Phonology has in fact been called functional phonetics. It is a separate study include language. The phonology of all language is different.

What is Phonetics?

            Phonetics is come from Greek word 'phono.' It means sound, voice. It is a branch of linguistics that comprises the study of the sounds of human speech. In other words, the general study of the characteristics of speech sounds is called phonetics. To describe speech sounds it is necessary to know what an individual sound is and how each sound differs from all others.

                                                                         

Phonetics studies the medium of spoken language. Now, phonetics is a pure science which studies speech process, including the anatomy, neurology and pathology of speech. The phonetics part consists of the three phases of the speech communication channel, namely the production, acoustics, and perception of speech. Although the most important phenomena are listed as key words under only one topic each, they can be seen from several different viewpoints. Due to the fact that the focus is on processing acoustic data in the language and speech area, speech acoustics is given greater prominence. So we can say the phonetics is

• how they are produced and which articulators ate take part in producing particular speech sounds.
• how they are transmitted through the air from the speaker to the listener and
• how they are received and perceived by dint of his or her auditory ability.

Briefly, phonetics is a science of speech sounds, which studies their production, transmission and reception in an impartial and practical manner, even in laboratory.
