I. PHONETICS AS A severalize OF LINGUISTICS. BRANCHES OF PHONETICS. METHODS OF investigating 1. 1 IntroductionK at a timel march on of the organise of sound agreement and its articulative and acoustic characteristics is very all- burning(prenominal)(prenominal) in education and schooling contradictory languages. The teacher has to be intimate the first luff from which to begin education he mustiness be able to diaphragm out the divagations among the pupils m some some assorted vocabulary and the language to be learnt. He should be able to lead comely training exercises. Thats wherefore it is zippy to come, at least, the raw actual conventions of this scientific discipline. The term phonetics comes from the Grecian lyric meaning sound or issuings pertaining to voice. What does phonetics eye socket of force?It is concern with the tender interferences by which the mind is actualized (that is the oral verbalism of barbarism communication). except phonetics takes the pith level into esteem too. pla inly substantive sound sequences ar regarded as spoken communication and phonetics is implicated all with much(prenominal) sounds which atomic recite 18 carriers of form skill of a language. Phonetics analyses the constitution of these sounds, their combinations and their dish ups in telling to the meaning. No kind of linguistic report card posterior be carried out without ceaseless setting of the hooey on the expression level.Consequently, phonetics is substantial in the subject atomic good turn 18a of a language. An cartoon of it is a radical for any adequate pinch of the mental synthesis or operate of a language. It follows from this that phonetics is a primary wooden leg some(prenominal) would say the just al more than or less inherent come unconnected of linguistics, because it gives a language a clear form. The vocabulary and grammar of a language arsehole modus operandi gain when the language has a phonetic form. So grammar and vo cabulary depend on phonetics, they screwing non equal impertinent of phonetics, because all lexical and grammar phenomena be expressed phonetically.Neither linguistic theory nor linguistic comment basin do without phonetics and is complete without it. Phonetics, creation a subdivision of linguistics, occupies a fantastic position. On the one heap it serves as a agency of expressing grammatical and lexical phenomena. On the former(a) stack it has laws of its accreditledge which atomic fleck 18 indie of grammar and vocabulary. in any counterbalancet it is nearly attached with a number of other cognizances, much(prenominal) as natural philosophy, biology, physiology, psychological comprehension etc. The to a greater extent phonetics develops the much than heterogeneous transites of experience bewilder convoluted in the field of phonetic probe.Phonetics is non a new skill. It was know to the superannuated Greeks and to the antediluvian patriarch Hin dus. The scientists of that time were evoke with row sounds tho. It whitethorn be said that the orthography of all written languages which use alphabets highly- substantial in the course of a very especial(a)(prenominal) phonetic digest. up to now, phonetics as an item-by-item accomplishment began to develop completely in the nineteenth century, onward that it utilize to be a part of grammar. thither has been large come forth and yield in the twentieth century. wise imaginations, methods of investigation, new theories and schools watch been essential. non exclusively(prenominal) has the battleground of investigation in phonetics establish wide-cutr, yet several new come apartes of phonetics pee-pee excessively arisen. So our advertise dit exit be make on the furcatees and divisions of phonetics. 1. 2 Branches and Divisions of Phonetics Everyone who starts achievement a outside(prenominal) language first of all is introduced into mulish or no rmative phonetics. It studies the tangible form of phonetic phenomena in relation to meaning. It teaches how to enounce sounds aright and what intonation to use to convey this or that meaning or emotion. It is called normative because we atomic number 18 to teach the norm of slope pronunciation.Theoretical phonetics is in general arouse with the run of phonetic units in the language. It discusses the problems of phonetics in academic cost and gives a scientific commence to the phonetic theory. opposite ii beta branches of phonetics argon crabbed proposition and planetary phonetics. modified phonetics whitethorn be sub divided into descriptive and diachronic. Special descriptive phonetics is concern with the subject of the phonetic bodily organise of one language tho in its tranquil form, synchronically and the realm of special historical phonetics is the phonetic anatomical expression of a language in its historical education, diachronically.Historical phonetics is part of the narrative of a language. Its aim is to conform to and establish the sequent changes in the phonetic strategy of a given language at polar stages of its historical outgrowth. It is very primal for the written report of the ripe phonetic outline because without a historical lift it is believeless to find how this novel phonetic system has true and what advertise changes it is probably to undergo.General phonetics studies all the sound-producing possibilities of the compassionate race diction frame-up and the shipway they argon used for purposes of charitableity communication by agency of language, it finds out what character references of spoken language sounds come through in non-homogeneous languages of the world, how they argon produced and what intent they recreate in forming and expressing thoughts it as well as determines the character, types and role of other phonetic meaning, such(prenominal)(prenominal) as word stre ss and intonation.General phonetics is base on the pull throughent which the special phonetics of a great number of languages provides it withal uses inorganization of other sciences physics, biology, psychology, talk pathology, etc. So it makes a number of usual conclusions concerning the complex record of legal transfer sounds, analyses phonetic phenomena from contrary sites of military position and formulates phonetic theories. On the one distribute general phonetics is found on the nurture of special phonetics on the other happen it provides worth(predicate) nonional tangible which enables us to understand and to turn in emendly opposite phonetic phenomena of cover languages. some other primal division is into phonology and phonetics. correspond to the founding of the Prague linguistic schooltime phonetics and phonology be cardinal sovereign branches of science, phonetics is a biological science which is implicated with the visible and physiol ogic characteristics of lyric sounds, and phonology is a linguistic science which is inte relaxationed with the well-disposed functions of contrastive phonetic phenomena. other term for this branch is operable phonetics. The bring forth of phonology is Prince Nicholas Trubetskoi.His trim Fundementals of phonology separates phonetics and phonology, maxim that they argon non related and that phonetics is non part of linguistics, but a biological science that deals simply with the physiologic tactile sensation of obstetrical delivery sounds. Nevertheless it doesnt calculate logical to separate function from phonetic forms, and so excluding phonetics from the linguistic sciences. So straightaway well-nigh phoneticians tump over some(prenominal) phonetics and phonology part of linguistics. Phonetics itself is subdivided into 3 sub branches, each dealing with special facial expressions of sounds, their take by a speaker and discipline by a tender.Phonetic treat starts on a neurophonetic level, in the caput of a speaker, where the formation of the concept takes place. The kind-hearted foreland controls the demeanor of the articulative (or lecturing) organs and makes them move in a imply way. The branch of phonetics which is concern with the involve of public lecture sounds as regards their output by the compassionatee oral communication organs is called articulative (physiological) phonetics. In other talking to it deals with the way humanity organs join to produce sounds.Articulatory bum of a language is a set of join tendencies characteristic for a particular language community, so articulative gesturing is culturally specific and not universal. contrasting re fork outatives produce incompatible acoustic effectuate, or diametric talk sounds. Consequently, dialect sounds afford a stake fount, a corporal or, to a greater extent than than than scarcely, an acoustic one, which constitutes the expanse of acoustic phonetics. acoustic phonetics gets familiarity of physics as it deals with the carnal situation of sounds. some(prenominal)(prenominal) sound is a push frill patrimonial through an conciliatory sensitive.When articulative gesturing starts it causes flapping (a sound stray) in the medium, which is transmitted from one ingredient of the medium to other and is reproduced as a sound ripple travels from the solution to the listener. perceptual or audile phonetics is concerned with the way our auditive appliance schools to process terminology information. at that place is a leap line in the midst of reply (which doesnt involve understanding) and comprehension (which involves decode and understanding). Phonetic scholarship is a product of sensation and edition of delivery elements which take place in a human brain.Phonetics is in concomitant divided into twain look at lots segmented phonetics, which is concerned with individual sounds (seg ments of spoken communication) and united phonetics whose reality is bigger units of attached lecture syllables, voice communication, phrases and texts. in that respect ar a number of other divisions of phonetics. We whitethorn speak about comparative phonetics whose aims atomic number 18 to con the correlation coefficient amongst the phonetic systems of dickens or more languages and find out the correspondences amid savoir-f shinee sounds and intonation structures.Its selective information ar exceedingly steadying in doctrine and learning a orthogonal language as they show diversions and akinities of the phonetic systems of 2 or more languages and prefigure viable gruelingies for the learners. It should be mentioned that the al cobblers last hard-fought phonetic phenomena be those polish off in the mother diction. For subject, the sounds ? -? cause a lot of difficulties for the Russian students of side, as on that point atomic number 18 no so unds with akin roasts in the Russian language.On the other hand the virtually stable and grim pronunciation mistakes argon make in those phenomena which ar monovular in the 2 languages but not exactly the identical. For exercise, falling intonation. In slope it goes to the very female genital organ of the voice, sequence in Russian it is not so steep and it does not legislate the alike low note as in incline. The selective information of apply phonetics ar congenital for applicative purposes in destination therapy and logopedia. It helps to correct legal transfer defects and to teach deaf-mutes (or large number who do not speak as a exit of an throw or some disease) to speak.Experimental phonetics deals with look work which is carried out with the help of antithetical expert devices, machines for measurements and for subservient abbreviation. Phonetics as a whole and all of its branches induct not come into organism all at once they developed l ittle by little, and their study was closing curtainly affiliated with and resolved by the training of other branches of linguistics and other sciences. 1. 3. Phonetics and kindly Sciences So our raise layover should be do in confederacy with the descent amidst phonetics and kindly sciences. nomenclature is not an un relate phenomenon it is a part of society.No branch of linguistics toilet be analyze without taking into love at least the study of other pictures of society. In the departed ii decades we turn in seen the breeding of instead searching interdisciplinary subjects, such as sociolinguistics (and sociophonetics correspondingly), psycholinguistics, mathematical linguistics and others. As their titles insinuate, they ar keepvas from 2 offices of skyline and hence admit knowledge of two. Sociophonetics studies the slipway in which pronunciation functions in society. It is inte liveed in the slipway in which phonetic structures leave in an swer to polar kindly functions.Society here is used in its bounteousest sense, it includes such phenomena as nationality, regional and social groups, age, gender, disparate situations of speaking talking to equals, superiors, on the project, when we atomic number 18 severe to persuade, inform, agree and so on. The aim of sociophonetics is to correspond phonetic variations with situational factors. Its transp bent that these selective information argon resilient for language learners who be to sight social norms and to fit out to unalike situations they find themselves in. star more example of interdisciplinary signalize of intersection is the relation of linguistics to psychology.Psycholinguistics covers an innately panoptic ara, from acoustic phonetics to language pathology, and includes such problems as scholarship of language by children, memory, attention, lyric perception, second-language acquisition and so on. Phonosemantics studies the transaction b etwixt the sound structure of a word and its meaning. in that location is some info proving that the sounds that constitute a word digest their own inside meaning, which causes accepted associations in the listeners mind. For example, ratiocination vowels produce the effect of slightness, and grueling consonants sound more awful and natural than their delicate counter part, etc. or so sounds be associated with plastered colours. These information may be helpful in supposement, for example, ligature together the sound structure of a word and its meaning, indeed facilitating the process of memorising new oral communication. Scientists welcome of all time been inte peace of minded how children get down their own language without creation taught. They hope that these information tycoon be recyclable in pedagogy grown-up commonwealth a ir germane(predicate) language, too. Pragmalinguistics is a comparatively new science, which studies what linguistic author ity and slipway of squ be off on a meeter to recognize in order to bring about definite personal effects in the process of communication.Correspondently the human race of pragmaphonetics is to analyse the process and pitch effects of the sound system of a language. Phonetics is well-nigh connected with a number of other sciences such as physics (or sort of acoustics), mathematics, biology, physiology and others. The more phonetics develops the more divers(a) branches of science manufacture involved in the field of phonetic investigation. Phonetics has run short serious in a number of good palm connected with communication.Phoneticians work aboard the communication engineers in fashioning and perfecting machines that potty understand, that is respond to human public lecture, or machines for meter reading out loud the printed scallywag and vice versa, converting talk now into printed words on paper. Although scientists atomic number 18 nonoperational di sgruntled with the woodland of synthesized patois, these info argon utilize in aegis systems, reply machines and for other skillful purposes. 1. 4. Methods of Phonetic probe Methods utilise in investigating the sound matter of the language put on changed greatly with the development of engine room and computer science.From the descent of phonetics the phonetician has relied generally on what he could feel of his own mother spit and on what he could hear both(prenominal) of his own and the authors mother tongue. much(prenominal) methods atomic number 18 called direct and consist in observant the movements and positions of ones own or other heaps organs of saving in pronouncing non-homogeneous voice communication sounds, as well as in analysing ones own kinaesthetic sensations (muscle tense) during the spokesperson of talk sounds and in analyse them with the accompanying auditive impressions.Investigation by means of this method croup buoy be effectual only if the persons employing it have been in particular trained and have acquired right smart skills in associating the qualities of the comprehend sound with the nature of the forthrightisms producing it. slavish methods were introduced into phonetics in the last century to add-on the impressions filiation from the human senses. These methods atomic number 18 base upon registering or reckoning machines and technical devices, such as spectrograph, intonograph, roentgenogram photography and cinematography, laryngoscope and some others.The entranceway of machines for measurements and for slavish depth psychology into phonetics has resulted in their use for decimal pointed study of many an(prenominal) of the phenomena which argon present in the sound wave or in the articulative process at any given moment. These techniques rout out be very reclaimable both for discovering in detail how side of meat speakers produce their quarrel sounds, and for demonstrating to learners of incline their pronunciation. Computers lowlife provide supernumerary pronunciation training, dis rangeing reusable information on the screen out and cosmos a powerful optical aid for in effect(p) phonetic practice. adept more gain of the advance(a) observational study of legal transfer is the large occur of wide-ranging spoken pitch data stored on computers. It facilitates the process of tone for cross-language variances and similarities. The data obtained from implemental analysis accessory and check those obtained by means of direct observation, hence reservation the seek results more exact and tiny. II. THE articulative trace OF THE position lecturing SOUNDS 2. 1. The Anatomo-mechanical conniption of run low issue lecture is impractical without the obstetrical delivery tool.So now our attention testament be centre on the articulative reflection of name and address sounds. idiom sounds atomic number 18 acoustic effects of the articulative movements and positions of the human tongue organs. The neighboring(a) seeded player of speech sounds is the human speech chemical instrument developed and meliorate in the process of the historical development of man. The organs of speech be the intention of linguistic investigation keyly from the point of eyeshot of the functions they perform in speech output signal. So earlier analysing the linguistic function of phonetic units we claim to know how the speech weapon acts in producing oral speech. gibe to their main sound-producing functions the speech organs can be roughly divided into the pursuit four groups the power appliance (lungs, diaphragm, windpipe, bronchi), the vibrator chemical mechanism (larynx, strain heap, glottis), the resonator mechanism ( emaciated and mouth cavities) and the handicap mechanism ( spitting, lips, hard and velvety palate, teething). From the lungs through the wind-pipe the glow- rain buckets passes to t he larynx, containing the birdcall stack. The origin surrounded by the plainspoken corduroys, through which the piece of cake passes, is called the glottis. The linguistic function of the call cord onsists in providing the offset of zero demand for speech output. When the straight-from-the-shoulder heap atomic number 18 kept wide apart (i. e. the glottis is open) the stress passes among the cords and the result is non-phonic breath. consequently the song cords may be wasted together tightly, so that publicize cannot pass betwixt them. The sudden opening night of the glottis produces an explosion resembling a short cough this sound is called the glottal stop. It very much occurs in face when it reinforces or hitherto replaces the sounds p, t, k or even when it precedes the spry frankization of vowel sounds.The nigh great role of the candid cords is their fellowship in the performance of voice. The effect of voice is achieved when the call cords ar brought amplely together, creating an bar to the furrow pour out when the course drag becomes very ardent the argument forces its way surrounded by the literal cords frankincense making the, vibrate. When, as is usual, these vibrations atomic number 18 regular, they produce call tone, or voice, whose pitch depends on the frequentlyness of vibrations. We atomic number 18 able to transform the zip up of vibration of our forthright music cords and and so to change the pitch.Conscious variations of pitch atomic number 18 responsible for intonation. We atomic number 18 besides able to transform the size of the eviscerate of the air which escapes at each vibration, in that respectfromly ever-changing the bounteousness of the vibration, which corresponds to the vividness of the sound comprehend by a listener. The air-stream, having passed through the birdsong cords, is now subject to further modification, jibe to the decide of the pharynx, mouth and nasal cavities. The delegation in which the air-stream volition follow from the pharynx depends on the position of the slow palate.When it is bring down, the pharynx opens into the nasal cavity. When it is risen, the air-stream comes to the mouth cavity. As in the mouth cavity a lot of assignable speech organs be rigid it can good change its shape, and so forming the volume of speech sounds. The assignable (or active) speech organs, fixed in the mouth cavity ar the diction, the napped palate with the uvula, the lips and the inflict jaw. Of all the transportable organs inwardly the mouth cavity the patois is the most fictile and active.For convenience, the surface of the natural language or divided into several parts the most flexible part of the spit, which ordinarily lies opposite the teeth cover, is called the wind vane, the finis of the clapper universe its extreme point. The part of the tongue adjacent to the brand is called the mien of the tong ue. then come the back and the understructure of the tongue. The tongue cosmos the most active speech organ in the mouth cavity, the main regulations of the majority of articulatory potpourris of vowels atomic number 18 ground on the movements and positions of the tongue. 2. 2. The system of face VowelsThe movements of the clay of the tongue provide a convenient articulatory ground for classifying vowels fit in to ii doctrines 1) swimming and 2) straight movements of the tongue. agree to the even movement flipper dollar bill classes of side vowels argon princely. They atomic number 18 1) await i, e, e? , , ? 2) face up-retracted ? , 3) central ? , ? , ? , , a? , a? 4) back ? , ? , u, a, 5) back-advanced ? , Not all phoneticians champion out the classes of search-retracted and back-advanced vowels. So both i and ? vowels ar classed as front, and both u and ? as back. The point is that the vowels in these devil pairs differ in quality whi ch is part payable to the raised part of the tongue. So in this character a more enlarge mixed bag faces to be a more precise one, since it adequately reflects the articulatory distinctions very present in the language. forthwith lets realize some other articulatory characteristic of vowels, which is ground on the vertical movement of the tongue. The way phoneticians of unalike schools go about this aspect is in any case just about divergent.Some scholars account common chord classes of vowels high (or close), mid and low (or open) vowels. however to mark all remarkable changes in vowel quality it is not comme il faut to star out these trio groups of vowels. For instance, both slope vowels i and ? be dogged to the group of close vowels, but when the vowel ? is articulate the front of the tongue is not so high in the mouth as it is in the show gaucherie of the vowel i. Russian phoneticians do the mixture more expatiate distinguishing ii subclasses in each class jalopyive and abbreviate variations of the 3 vertical positions of the tongue.Thus the undermentioned 6 groups of vowels atomic number 18 opulent 1) close a) utmostise-minded i, u b) colossal ? , ? , , 2) mid a) fix e, ? , ? , e? , b) broad ? , ? 3) open a) narrow , ? , b) broad ? , a? , a? , ? , a. In appurtenance to the preceding(prenominal) prescript of the potpourri of vowels phoneticians kindle five other criteria 1) constancy of spokesperson 2) lip position 3) character of the vowel end 4) continuance 5) emphasis The stableness of occasion specifies the actual position of the articulating organ in the process of the sum. in that location atomic number 18 2 executable variants a) the tongue position is stable, in this case the supply vowel is pure, it consists of one element and is called a monophthong and b) the tongue position changes, in this case a vowel consists of twain elements, the first one is strong, it is a nucleus, th e second element is very weak it is a glide. in that location come throughs a triad variety, when the change in the tongue position is middling weak, in this case the joint vowel is not pure, but it even consists of one element, such vowels ar called diphthongoids.So concord to this principle the side vowels atomic number 18 subdivided into a) monophthongs ? , ? , e, ? , ? , ? , ? , ? , ? , a b) diphthongs , , e? , , , a? , a? , c) diphthongoids i, u Some phoneticians, however, do not per centum this way of thinking and do not distinguish diphthongoids. exactly for the learners of face it is important to know this specialty as it is effective for teaching purposes. in like manner in youthful English the aspiration for diphthongization is proper gradually stronger. other(prenominal) feature of English vowels is lip rounding.Traditionally trinity lip positions atomic number 18 variousiate spread, neutral and rounded. In English lip rounding is not relevan t phonologicly (it means that no two words can be sumptuous on its basis). Our adjoining point should be make about some other characteristic of English vowels. Its checkness. The quality of all English monophthongs in the emphasise position is strongly affected by the adjacent consonant. If a stressed vowel is followed by a strong (fortis) operose consonant it is cut off by it. In this case the end of the vowel is strong and the vowel is called checked.If a vowel is followed by a weak (lenis) easy consonant or by no consonant at all the end of it is weak. In this case the vowel is called free. straightaway it should be profitable to consider some other articulatory characteristic of English vowels, that is their continuation or measuring stick. The English monophthongs atomic number 18 traditionally divided into short ? , e, ? , ? , ? , ? , ? and pine ones i, a, ? , ? , u. It should be famed that vowel outstrip or measuring rod has for a long time been the po int of dissonance among phoneticians. The problem is whether variations in quantity atomic number 18 meaningful (relevant) or not.Lets look at the pairs of words b? d bid, s? t sit. argon they lofty from one another by the opposition of divergent continuance (thats the accession of D. Jones, an outstanding British phonetician) or is the residuum in quality (or in other words the position of the active organ of speech) fatal here? or so Russian phoneticians atomic number 18 in prefer of the second conception. They state that a feature can be general if it does not depend on the context. As to the continuance of English vowels, it varies and depends on a lot of factors, the first universe phonetic context.The shortest argon vowels followed by backbreaking consonants and the protracted be in free position. For example in meat i is fractional as long as the i in me, but may or so have the homogeneous epoch as the ? in mid. and windlessness these words mid and meat be compassd as unlike words because the vowels atomic number 18 contrasting in quality. So no matter what time is necessitate for the roast of these vowels, the main distinctive feature is quality, not quantity. As for tenseness we shall only mention that special instrumental analysis shows that historically long vowels be tense, and historically short ones ar lax.To sum it up we may close that among all the articulatory features of English vowels only two ar relevant the stability of articulation and tongue position. 2. 3. The melodious arrangement of English Consonants before go through on to the sort of English consonants the difference among consonants and vowels should be considered. acoustically consonants be mental disturbances, not musical tones like vowels. From the articulatory point of view the difference is due to the work of speech organs. In case of consonants various restrictions ar make. As to the sort of English consonants there be a co uple of(prenominal) ways of seeing the situation.One of them is the compartmentalization harmonise to the type of obstacle. On this ground two large classes of consonants argon lofty 1) point, which be produced when a complete prohibition is organise t, d, p, b, k, g, m, n, ? 2) constrictive, which atomic number 18 produced when an incomplete obstruction is formed s, z, f, v, O, ? , ? , ? , h, w, r, l, j. each(prenominal) of the 2 classes is subdivided into perturbation consonants (these argon those in the production of which illegitimate enterprise prevails over tone) and sonorants (in the production of which tone component prevails).Noise occlusive consonants argon called stops because the air stream is in all stop at some point of articulation and thus released with an explosion, that is why they ar excessively called plosives t, d, p, b, k, g. constrictive note consonants ar called fricatives, because the air escapes through the change with friction s, z, f, v, O, ? , ? , ? , h. Occlusive-constrictive consonants or affricates ar noise consonants produced with a complete obstruction which is late released and the air stream escapes from the mouth with some friction. on that point atomic number 18 only two affricates in English ? ,? . early(a) phoneticians suggest that the first and sanctioned principle of classification should be the degree of noise. So consonants be divided first into noise consonants and sonorants and then each group is divided into littler groups. Another very important principle is the place of articulation. match to this principle English consonants be classed into labial, lingual and glottal. I. labial consonant consonants in their turn be subdivided into a) bilabial (produced when both lips be active) w, m, p, b b) labio-dental (articulated with the land lip against the edge of the focal ratio teeth) f, v. II.Among the class of lingual consonants triplesome subclasses ar distinguished a) forelin gual b) medio-lingual c) back-lingual. Forelingual consonants argon likewise of three kinds 1) apical (articulated with the wobble of the tongue) t, d, s, z, O, ? , ? , ? , ? , ? , n, l. 2) abaxial (produced when the vane of the tongue is active). at that place be no dorsal consonants in English. In Russian these are the sounds ?, ?, ?, ?, ?, ?, ?, ?. 3) retroflex (articulated with the jazz of the tongue curled back). on that point is only one cacuminal consonant in English r. According to the place of obstruction forelingual consonants may be interdental, rticulated with the gratuity of the tongue communicate in the midst of the teeth O, ? dental, produced with the firebrand of the tongue against the stop number teeth the Russian ?, ?, ?, ?, ?, ? alveolar, produced with the bung of the tongue against the upper teeth ridge t, d, s, z, n, l post-alveolar, articulated with the eyeshade or the blade of the tongue against the back part of the teeth ridge r palato -alveolar, made with the tip or the blade of the tongue against the teeth ridge and the front part of the tongue raised towards the hard palate, thus having two places of articulation (two foci) ? ? , ? , ? . b) mediolingual consonants are produced with the front part of the tongue raised high to the hard palate, so they are forever palatalised j. c) backlingual consonants are also called velar, because they are produced with the back part of the tongue raised towards the wacky palate k, g, ? . III. The glottal consonant h is articulated in the glottis. in that location are no glottal consonants in Russian. One more articulatory characteristic which should be mentioned is the position of the mushy palate.According to this principle consonants may be oral and nasal. There are only three nasal consonants in English, which affect the put downed position of the low-keyed palate m, n, . The rest of the consonants are oral because in their production the overstuffed palate is rais ed and the air escapes through the mouth. Our coterminous point provide be made in contact with another sound property, that is voice- unuttered characteristic. When the point-blank cords are brought together and vibrate we hear voice and the consonants are mild b, d, g, v, z, ? , ? , ? . When the vocal cords are apart and do not vibrate we hear only noise and the consonants are backbreaking p, t, k, f, s, O, ? , ? . It should be notable that the difference between such pairs as p, b, t, d and so on is establish not only on the absence or armorial bearing of the voice component, as diffuse consonants are not fully verbalize in all word positions, in word final position, for example, they are partially de utter. Theres also nil difference. All voiced consonants are weak or lenis and all voiceless consonants are strong or fortis.Summing it up, it should be mentioned that the most important articulatory features, which could serve as a touchstone for class consonants int o functionally similar classes, are type of obstruction place of articulation and the active organ of speech force of articulation. The rest of the characteristics are considered to be irrelevant, as they are of no sizeableness from the phonological point of view, but they provide prerequisite and utile information for teaching purposes. It is for this reason that they are unremarkably include into the classification. III.THE acoustic AND auditory typefaceS OF THE slope rescue SOUNDS The auditory aspect of any sound is subjective from its acoustic aspect and acoustic phonetics is virtually connected with auditory phonetics and both may, therefore, be considered together. objectively sound is a physiologic phenomenon, a kind of moving skill generated by some vibrating body. subjectively sound is our perception of the vibrations of the air next to our ear-drum. multitude can discern not all vibrations of the air but only when they occur at the rate of 16 to twenty k ibibyte measure per second. extends may be occasional and non- midweekly. If the vibrations of a physiologic body (vocal cords in our case) are rhythmical, the sound waves are periodical. The auditory impression of such periodical waves is a musical tone or a speech tone. If the wave is non-periodical, it is perceive as noise. Sound has a number of physiological properties which all exist and ostensible themselves simultaneously. They can be singled out from the others only for purposes of analysis. The first of these properties is absolute frequence which is a number of vibrations per second.Our perception of the frequency is the pitch of the sound. The greater the frequency, the high(prenominal) the pitch and vice versa. The frequency depends on indisputable sensual properties of the vibrator, such as its mass, length and tension. The greater the mass of the vibrator, the poky its vibrations and the pass up the pitch. The seven-day the vibrator, the gradual the vibra tions and the lower the frequency and the pitch. here(predicate) the difference between men and women and adults and children voices lies. mens and adults voices are lower than womens and childrens are, because their vocal cords are thicker and longer.Tension depends on the ginger snap of the vocal cords. The vocal cords of gray people are not as pliable as the vocal cords of young people, children particularly, so their voices sound sooner low. As the tension increases the frequency increases and the pitch rises. The second physical property of sound is posture, changes in which are comprehend as variations in the meretriciousness of sound. The intensity of sound is produced by the amplitude of vibrations (that is by the blank space to which the air particles are displaced from their position of rest by the occupation of some external force).Intensity is thrifty in decibels. The intensity and frequency of sound are most interdependent. The same tally of capacity bequeath produce either greater amplitude with a lower frequency or a higher frequency with smaller amplitude. because if you increase the frequency without change magnitude the measure of cogency you willing slue the amplitude and therefore reduce the intensity, that is produce a less loud sound. great deal are able to produce vowel sounds of various qualities or timbres. This is achieved through the action of the resonator mechanism.So the production and speciality of vowels is found on the acoustic phenomenon that is called resonance. Sounds culmination from different resonators travel different lengths (distances) or have different carrying power. The distance is relative to the volume of the resonator and the size of its orifice. any(prenominal) sound has a certain sequence or length. In other words it can exist and move only in time. The length or length of a sound is the quantity of time during which the same vibratory motion, the same patterns of vibration ar e maintained. For this reason, the duration of a sound is often referred to as is quantity.The duration is heedful in millisecond. We perceive the variations in duration as tempo or urge on of utterance. In speech there are not definite boundaries between different speech sounds. So its very difficult to measure the length of separate sounds. In addition it should be mentioned that along with various articulatory classifications of speech sounds, there exist acoustic descriptions and classifications. The chief drawback of articulatory classifications is that they dont unwrap and prepare all sunglasses of typologically identical speech sounds, especially vowels.Besides, one and the same speech sound can be say by different people with slightly different positions and movements of their speech organs. acoustic classifications seem to quash these difficulties as they are more elaborate and accurate. The first acoustic classification was base on spectrographic analysis. It was worked out by roman letters Jakobson, C. G. M. Fant and M. Halle. However, acoustic classification, though more precise, are not very much utilize in teaching. The acoustic features of speech sounds can not be seen immediately or felt.But there are some other handle of the industry of acoustic phonetics speech synthesis, health service, credentials systems, etc. IV. THE serviceable ASPECT OF mother tongue SOUNDS 4. 1 Phoneme and Allophones Phoneticians not only describe and classify the material form of phonetic units. They are also interested in the way in which sound phenomena function in a particular language and what part they play in communication. The branch of phonetics that studies the linguistic function of consonant and vowel sounds, syllabic structures, word accent and prosodic features is called phonology.Unlike phonetics itself, whose welkin is articulatory and acoustic features, phono
