Language as a sign system can be discussed in terms of articulation i.e. exposing the matter of the sound system as its material formulation. In that sense language can be researched in terms of Phonetics - the sounds, accent, intonation as its material side and Phonology i.e. the sounds and their functionalrole in the language system. Phonetics and Phonology are two different sciences whereas Phonetics is considered as a helping linguistic discipline which is about the sound notions of the word apart from their linguistic function which is discussed further in Morphology, Syntax and Semantics. Phoneticsdoes not deal with the sound complex and its meaning but the material side of the sounds and human speech i.e. the physiological description of the sounds.Within every foreign language learning and teaching, the pronunciation i.e. the speaking skill is essential. In order to improve English language pronunciation, one needs to acquire the rules of Phonetics and Phonology that deal with the sounds, their physical properties and the relationship of sounds andmeaning along with the phonetic transcription.Key words: English language, pronunciation, Phonetics, Phonology, IPA.
