Since the late 1960s the experimental investigation of coarticulation has developed into a major area of research. The phenomenon of co-articulation became apparent with the detailed investigation of coarticulatory effects. Articulation is how speech sounds are produced, made or articulated. Co-articulation is the way in which the movements of different articulators affect each other and the ways in which preceding and following articulations of an individual articulator affect its current articulation. “The process of making one sound almost at the same time as the next is called coarticulation”. There are two well known co-articulation effects: Assimilation Elision ASSIMILATION Assimilation is a regular and frequent sound change process by which a phoneme changes to match an adjacent phoneme in a word. A common example of assimilation is vowels being nasalized before nasal consonants as it is difficult to change the shape of the mouth sufficiently quickly. “When two phonemes occur in sequence and some aspects of one phoneme is taken or copied by another, the process is known as assimilation”. Types of Assimilation PROGRESSIVE ASSIMILATION If the phoneme changes to match the preceding phoneme, it is progressive assimilation. Progressive assimilation is also known as left-to-right or perseveratory or preservative, lagging or lag assimilation. “If a phoneme is affected by one that comes earlier in the utterance, this assimilation is termed as progressive”. For example: Baking, Organ, Bacon… REGRESSIVE ASSIMILATION If the phoneme changes to match the following phoneme, it is regressive assimilation, also called right to left or anticipatory assimilation. “If a phoneme is affected by one that comes later in the sentence, this is called regressive assimilation”. For example: I can go. Let me check! Good morning! Good boy. RECIPROCAL ASSIMILATION Very occasionally two sounds (invariably adjacent) may influence one another in reciprocal assimilation. When such a change results in a single segment with some of the features of both components, it is known as coalescence or fusion. This notion was identified by Sanskrit Grammarians as Sandhi or fusion. “If there is a mutual influence between the two phonemes, it is reciprocal assimilation”. For example: What you want? Would you? In case you need it Has your letter come? Elision is the omission of one or more sounds such as a vowel, a consonant or a whole syllable in a word or phrase, producing a result that is easier for the speaker to pronounce. Sometimes a sound may be elided for euphonic effects. “The term elision describes the disappearance of a sound”. Or “The omission of a sound segment which would be present in the deliberate pronunciation of a word in isolation is technically described as elision”. The reason of elision is, in some instances, the difficulty of putting certain consonants sounds together while maintaining a regular rhythm and speed. WORD-INTERNAL Weak, central vowels are elided when they occur in unaccented syllables between two consonants. Examples: certain, student, vision, classical, nasal, etc. Alveolar consonants are elided when they occur between two consonants. For example: handsome, postpone. AT WORD BOUNDARIES Word-final alveolars [t,d] are generally elided when they are preceded and followed by other consonants, especially when the following consonant is a plosive. Examples: next turn, best joke, send two, rubbed down. THINK OF SOME EXAMPLES OF ASSIMILATION AND ELISION IN URDU LANGUAGE Examples: ‘Ghalat’ spoken as ‘ghalt’ ‘Qadar’ spoken as ‘qadr’ Supra segmental Features DEFINITION 1. ‘denoting a feature of an utterance other than the consonantal and vocalic components, for example (in English) stress and intonation’ Retrieved From:http://oxforddictionaries.com/definition/ english/suprasegmental ‘of or relating to significant features (as stress, pitch, or juncture) that occur simultaneously with vowels and consonants in an utterance’ Linguistics . pertaining to or noting features o f speech,as stress, pitch, and length that accompany individual consonants and vowels and may ex tend over more than one such segmental ele ment;pertaining to junctural and prosodic features .

Greek sullabē, fromsun- 'together' + lambanein 'take‘ ‘a unit of pronunciation having one vowel sound, with or without surrounding consonants, forming the whole or a part of a word; for example, there are two syllables in water and three in inferno’. Retrieved from:http://oxforddictionaries.com/definiti on/english/syllable A syllable is a unit of sound composed of a central peak of sonority (usually a vowel), and the consonants that cluster around this central peak. Parts of a Syllable: 1.ONSET:( Optional) Initial segment of a Syllable 2. RHYME: ( Obligatory) Core of a syllable, consisting of a nucleus and coda 3.NUCLEUS/CENTRE/PEAK: (Obligatory)Central segment of a syllable Coda/Termination: (Optional) Closing segment of a syllable NOTE(A syllable thus has three positions): Nucleus/Centre/Peak Onset Coda/Termination A syllable is a unit of sound ,and, therefore we should look at the phonetic transcription of words and not their Orthographic representation. Phonetically ,a syllable is said to consist of a centre which has little or no obstruction to the flow of air and which sounds comparatively loud KINDS OF SYLLABLES Open Syllables Closed Syllables Syllables consisting of only a vowel Syllables where the central vowel is both preceded and followed by one or more than one consonant A Syllable is made up of two kinds of elements : Vowels Consonants The vowels are the obligatory elements and the consonants are the optional. A vowel can be a syllable by itself ,it may be preceded by one,two,or three consonants .Or it may be followed by one ,two, three, or four consonants. The vowel is the central element in a Syllable and is called the Nucleus. The consonants that precede the central vowel are called the Releasing Consonants while the consonants that follow the Central vowels are called Arresting Vowels. The structure of English syllable can thus be shown as: (CCC) V (CCCC) When two or more consonants occur together without a vowel between them in the same syllable, such consonants are said to form a CONSONANT CLUSTER e.g. the word (TEXTS ) has a four consonant-cluster at the end . When two or more consonants occur together in a word but belong to different syllables (e.g the consonants /n/ and /t/ in the word (CONTEXT),they are called ABUTTING CONSONANTS SYLLABIC CONSONANT In a Syllable, a nucleus is generally a vowel ,preceded or followed by consonants ,which are marginal elements but there are some special cases where the consonant is the nucleus of the syllable e.g.in words like Bottle cattle,kettle, cotton and mutton,the second syllable has two sounds ,both consonants either /tl/or /tn/.In such cases /t/ and /n/ occupy the nuclear position and are called SYLLABIC CONSONANTS ,represented as V.(i.e. not as C ) Stress ‘An emphasis given to a particular syllable or word in speech, typically through a combination of relatively greater loudness, higher pitch, and longer duration….. ’ http://oxforddictionaries.com/definition/english/stress A Syllable prronounced more prominently than the other syllables in the sme word is said to be STRESSED or ACCENTED syllable.A stressed syllable is often mentioned by a small vertical line just above and before its beginning ,as shown in ‘chapter and ad ’mire Primary stress Secondary stressI In English we find three kinds of syllables in term of stress : Syllables with primary or strong stress Syllables with secondary or weak stress Syllables with no stress There are four features that have been identified crucial in deciding stress placement The Phonological structure of these syllables,(i.e.the sequences of consonants and vowels making up the syllables The grammatical category of the words(i.e.whether the word is noun,adjective or a verb) The morphological structure of word i.e whether the word is Simple or Compound Examples of the words that are orthographically similar but differ in pronunciation ,in accordance with the Word Class to which they belong: (The stress is placed on the second syllable of Verb, but on the second syllable of nouns and adjectives) ABSTRACT CONDUCT CONTRAST PERFECT INSULT PERMIT REBEL RECORD Intonation Definition: In linguistics, the use of changing vocal pitch to convey grammatical information or personal attitude.

Only with strong feelings we use extra pitch height. Neutral Statement: Fall Rise: questioning, doubt, desire to continue conversation Fall-Rise: surprise, scepticism Level: boredom, lack of interest Fromkin, V. & R. Rodman (1988).
