1. PHONETICS AS A BRANCH OF LINGUISTICS
We begin our study of language by examining the inventory, structure and functions of the speech sounds. This branch of linguistics is called phonetics.
Phonetics (pronounced /fəˈnɛtɪks/, from the Greek: φωνή, phōnē, 'sound, voice') is a branch of linguistics that comprises the study of the sounds of human speech, or—in the case of sign languages—the equivalent aspects of sign.[1] It is concerned with the physical properties of speech sounds or signs (phones): their physiological production, acoustic properties, auditory perception, and neurophysiological status.
Phonetics, Phonology This is the level of sounds. One must distinguish here between the set of possible human sounds, which constitutes the area of phonetics proper, and the set of system sounds used in a given human language, which constitutes the area of phonology. Phonology is concerned with classifying the sounds of language and with saying how the subset used in a particular language is utilised, for instance what distinctions in meaning can be made on the basis of what sounds.
Phonetics is an independent branch of linguistics like lexicology or grammar. These linguistic sciences study language from three different points of view. Lexicology deals with the vocabulary of language, with the origin and development of words, with their meaning and word building. Grammar defines the rules governing the modification of words and the combination of words into sentences. Phonetics studies the outer form of language; its sound matter. The phonetician investigates the phonemes and their allophones, the syllabic structure the distribution of stress, and intonation. He is interested in the sounds that are produced by the human speech-organs insofar as these sounds have a role in language. Let us refer to this limited range of sounds as the phonic medium and to individual sounds within that range as speech-sounds. We may now define phonetics as the study of the
