Turbulence
–
Turbulence or turbulent flow is a flow regime in fluid dynamics characterized by chaotic changes in pressure and flow velocity. It is in contrast to a flow regime, which occurs when a fluid flows in parallel layers. Turbulence is caused by kinetic energy in parts of a fluid flow. For this reason turbulence is easier to create in low viscosity fluids, in general terms, in turbulent flow, unsteady vortices appear of many sizes which interact with each other, consequently drag due to friction effects increases. This would increase the energy needed to pump fluid through a pipe, however this effect can also be exploited by such as aerodynamic spoilers on aircraft, which deliberately spoil the laminar flow to increase drag and reduce lift. The onset of turbulence can be predicted by a constant called the Reynolds number. However, turbulence has long resisted detailed physical analysis, and the interactions within turbulence creates a complex situation. Richard Feynman has described turbulence as the most important unsolved problem of classical physics, smoke rising from a cigarette is mostly turbulent flow. However, for the first few centimeters the flow is laminar, the smoke plume becomes turbulent as its Reynolds number increases, due to its flow velocity and characteristic length increasing. If the golf ball were smooth, the boundary layer flow over the front of the sphere would be laminar at typical conditions. However, the layer would separate early, as the pressure gradient switched from favorable to unfavorable. To prevent this happening, the surface is dimpled to perturb the boundary layer. This results in higher skin friction, but moves the point of boundary layer separation further along, resulting in form drag. The flow conditions in industrial equipment and machines. The external flow over all kind of such as cars, airplanes, ships. The motions of matter in stellar atmospheres, a jet exhausting from a nozzle into a quiescent fluid. As the flow emerges into this external fluid, shear layers originating at the lips of the nozzle are created and these layers separate the fast moving jet from the external fluid, and at a certain critical Reynolds number they become unstable and break down to turbulence. Biologically generated turbulence resulting from swimming animals affects ocean mixing, snow fences work by inducing turbulence in the wind, forcing it to drop much of its snow load near the fence

Kannada
–
The language has roughly 40 million native speakers who are called Kannadigas, and a total of 50.8 million speakers according to a 2001 census. It is one of the languages of India and the official. The Kannada language is written using the Kannada script, which evolved from the 5th-century Kadamba script, Kannada is attested epigraphically for about one and a half millennia, and literary Old Kannada flourished in the 6th-century Ganga dynasty and during the 9th-century Rashtrakuta Dynasty. Kannada has a literary history of over a thousand years. Based on the recommendations of the Committee of Linguistic Experts, appointed by the ministry of culture, in July 2011, a centre for the study of classical Kannada was established as part of the Central Institute of Indian Languages at Mysore to facilitate research related to the language. Kannada is a Southern Dravidian language, and according to Dravidian scholar Sanford B, steever, its history can be conventionally divided into three periods, Old Kannada from 450–1200 CE, Middle Kannada from 1200–1700, and Modern Kannada from 1700 to the present. Kannada is influenced to an extent by Sanskrit. Influences of other such as Prakrit and Pali can also be found in the Kannada language. Literary Prakrit seems to have prevailed in Karnataka since ancient times, the vernacular Prakrit-speaking people may have come into contact with Kannada speakers, thus influencing their language, even before Kannada was used for administrative or liturgical purposes. Kannada phonetics, morphology, vocabulary, grammar and syntax show significant influence from these languages, some examples of naturalised words of Prakrit origin in Kannada are, baṇṇa derived from vaṇṇa, hunnime from puṇṇivā. Examples of naturalized Sanskrit words in Kannada are, varṇa, arasu from rajan, paurṇimā, Kannada has numerous borrowed words such as dina, kopa, surya, mukha, nimiṣa and anna. Pre-old Kannada was the language of Banavasi in the early Common Era, the Ashoka rock edict found at Brahmagiri has been suggested to contain words in identifiable Kannada. According to Jain tradition, Brahmi, the daughter of Rishabhadeva, the first Tirthankara of Jainism, invented 18 alphabets, including Kannada, which points to the antiquity of the language. Supporting this tradition, an inscription of about the 9th century CE, containing specimens of different alphabets and it has been claimed that the Greek dramatists of the 5th–4th century BCE were familiar with the Kannada country and language. This would show a far more intimate contact of the Greeks with Kannada culture than with Indian culture elsewhere, the palm manuscripts contained texts written not only in Greek, Latin and Hebrew, but also in Sanskrit and Kannada. In the 150 CE Prakrit book Gaathaa Saptashati, written by Haala Raja, Kannada words like tIr, tuppa, on the Pallava Prakrit inscription of 250 CE of Hire Hadagalis Shivaskandavarman, the Kannada word kOTe transforms into koTTa. In the 350 CE Chandravalli Prakrit inscription, words of Kannada origin like punaaTa, in one more Prakrit inscription of 250 CE found in Malavalli, Kannada towns like vEgooraM, kundamuchchaMDi find a reference. Pliny the Elder was a naval and army commander in the early Roman Empire and he writes about pirates between Muziris and Nitrias

Malayalam
–
Malayalam /mʌləˈjɑːləm/ is a language spoken in India, predominantly in the state of Kerala. It is one of the 22 scheduled languages of India and was designated as a Classical Language in India in 2013 and it was developed to the current form mainly by the influence of the poet Thunchaththu Ezhuthachan in the 16th century. Malayalam has official status in the state of Kerala and in the union territories of Lakshadweep. It belongs to the Dravidian family of languages and is spoken by some 38 million people, according to one theory, Malayalam originated from Middle Tamil in the 7th century. However, the current understanding proposes the separation of Malayalam from Proto-Dravidian in the pre-historic era, Malayalam incorporated many elements from Sanskrit through the ages. Before Malayalam came into being, Old Tamil was used in literature and courts of a region called Tamilakam, including present day Kerala state, silappatikaramit was written by Chera prince Ilango Adigal from Chunkaparra, and is considered a classic in Sangam literature. Modern Malayalam still preserves many words from the ancient Tamil vocabulary of Sangam literature, the earliest script used to write Malayalam was the Vatteluttu alphabet, and later the Kolezhuttu, which derived from it. As Malayalam began to borrow words as well as the rules of grammar from Sanskrit. This developed into the modern Malayalam script, many medieval liturgical texts were written in an admixture of Sanskrit and early Malayalam, called Manipravalam. The oldest literary work in Malayalam, distinct from the Tamil tradition, is dated from between the 9th and 11th centuries, the first travelogue in any Indian language is the Malayalam Varthamanappusthakam, written by Paremmakkal Thoma Kathanar in 1785. Due to its lineage deriving from both Tamil and Sanskrit, the Malayalam script has the largest number of letters among the Indian language orthographies, the Malayalam script includes letters capable of representing almost all the sounds of all Indo-Aryan and Dravidian languages. Malayalam serves as a language on the islands including the Mahl-dominated Minicoy Island. The word Malayalam originated from the Sanskrit resp, Malayalam words malai or mala, meaning hill, and elam, meaning region. Malayalam thus translates as hill region and used to refer to the land of the Chera dynasty, the language Malayalam is alternatively called Alealum, Malayalani, Malayali, Malean, Maliyad, and Mallealle. The word Malayalam originally meant only for the name of the region, Malayanma or Malayayma represented the language. With the emergence of modern Malayalam language, the name of the language started to be known by the name of the region, hence now, the word Malayanma is considered by some to represent the olden Malayalam language. The language got the name Malayalam during the mid 19th century, the origin of Malayalam, an independent offshoot of the proto-Dravidian language, has been and continues to be an engaging pursuit among comparative historical linguists. Together with Tamil, Toda, Kannada and Tulu, Malayalam belongs to the group of Dravidian languages

Malayalam script
–
The Malayalam script is a Brahmic script used commonly to write Malayalam, which is the principal language of Kerala, India, spoken by 35 million people in the world. Malayalam script is widely used for writing Sanskrit texts in Kerala. Like many other Indic scripts, it is an alphasyllabary, a system that is partially “alphabetic”. The modern Malayalam alphabet has 15 vowel letters,36 consonant letters, the Malayalam script is a Vatteluttu alphabet extended with symbols from the Grantha alphabet to represent Indo-Aryan loanwords. The script is used to write several minority languages such as Paniya, Betta Kurumba. The Malayalam language itself was written in several different scripts. A consonant letter, despite its name, does not represent a pure consonant, for example, ക is the first consonant letter of the Malayalam alphabet, which represents /ka/, not a simple /k/. A vowel sign is an attached to a consonant letter to indicate that the consonant is followed by a vowel other than /a/. If the following vowel is /a/, no sign is needed. The phoneme /a/ that follows a consonant by default is called an inherent vowel, in Malayalam, its phonetic value is unrounded, or as an allophone. To denote a pure consonant sound not followed by a vowel, the following are examples where a consonant letter is used with or without a diacritic. It is written left to right, but certain vowel signs are attached to the left of a consonant letter that it logically follows. In the word കേരളം, the vowel sign േ visually appears in the leftmost position, Malayalam was first written in the Vatteluttu alphabet, an ancient script of Tamil. However, the modern Malayalam script evolved from the Grantha alphabet, both Vatteluttu and Grantha evolved from the Brahmi script, but independently. Vatteluttu is a script that had evolved from Tamil-Brahmi and was used extensively in the southern part of present-day Tamil Nadu. Malayalam was first written in Vatteluttu, the Vazhappally inscription issued by Rajashekhara Varman is the earliest example, dating from about 830 CE. In the Tamil country, the modern Tamil script had supplanted Vatteluttu by the 15th century, a variant form of this script, Kolezhuthu, was used until about the 19th century mainly in the Kochi area and in the Malabar area. Another variant form, Malayanma, was used in the south of Thiruvananthapuram and it later evolved into Tigalari-Malayalam script was used by the Malayali, Havyaka Brahmins and Tulu Brahmin people, but was originally only applied to write Sanskrit

Devanagari
–
Devanagari, also called Nagari, is an abugida alphabet of India and Nepal. It is written left to right, has a strong preference for symmetrical rounded shapes within squared outlines. The Nagari script has roots in the ancient Brāhmī script family, the Nagari script was in regular use by the 7th century CE and it was fully developed by about the end of first millennium. Nagari has been the primus inter pares of the Indic scripts, the Devanagari script is also used for classical Sanskrit texts. The Devanagari script is closely related to the Nandinagari script commonly found in ancient manuscripts of South India. Devanagari script has forty-seven primary characters, of which fourteen are vowels, the ancient Nagari script for Sanskrit had two additional consonantal characters. The script has no distinction similar to the capital and small letters of the Latin alphabet, generally the orthography of the script reflects the pronunciation of the language. Devanagari is part of the Brahmic family of scripts of India, Nepal, Tibet and it is a descendant of the Gupta script, along with Siddham and Sharada. Medieval inscriptions suggest widespread diffusion of the Nagari-related scripts, with biscripts presenting local script along with the adoption of Nagari scripts, the 7th-century Tibetan king Srong-tsan-gambo ordered that all foreign books be transcribed into the Tibetan language. Other closely related scripts such as Siddham Matrka was in use in Indonesia, Vietnam, Japan, Sharada remained in parallel use in Kashmir. Nāgarī is the Sanskrit feminine of Nāgara relating or belonging to a town or city and it is a phrasing with lipi as nāgarī lipi script relating to a city, or spoken in city. The use of the name devanāgarī is relatively recent, and the older term nāgarī is still common, the rapid spread of the term devanāgarī may be related to the almost exclusive use of this script to publish Sanskrit texts in print since the 1870s. As a Brahmic abugida, the principle of Devanagari is that each letter represents a consonant. This is usually written in Latin as a, though it is represented as in the International Phonetic Alphabet, the letter क is read ka, the two letters कन are kana, the three कनय are kanaya, etc. This cancels the inherent vowel, so that from क्नय knaya is derived क्नय् knay, the halant is often used for consonant clusters when typesetting conjunct ligatures is not feasible. Consonant clusters are written with ligatures, for example, the three consonants क्, न्, and य्, when written consecutively without virāma form कनय, as shown above. Alternatively, they may be joined as clusters to form क्नय knaya, कन्य kanya and this system was originally created for use with the Middle Indo-Aryan languages, which have a very limited number of clusters. When applied to Sanskrit, however, it added a deal of complexity to the script

Hangul
–
The Korean alphabet, known as Hangul in South Korea and as Chosŏngŭl/Chosŏn Muntcha in North Korea is the alphabet that has been used to write the Korean language since the 15th century. It was created during the Joseon Dynasty in 1443 by King Sejong the Great, in South Korea, Hangul is used primarily to write the Korean language as using Hanja in typical Korean writing had fallen out of common usage during the late 1990s. In its classical and modern forms, the alphabet has 19 consonant and 21 vowel letters, however, instead of being written sequentially like the letters of the Latin alphabet, Hangul letters are grouped into blocks, such as 한 han, each of which transcribes a syllable. That is, although the syllable 한 han may look like a single character, each syllabic block consists of two to six letters, including at least one consonant and one vowel. These blocks are arranged horizontally from left to right or vertically from top to bottom. Each Korean word consists of one or more syllables, hence one or more blocks, of the 11,172 possible Hangul syllables, the most frequent 256 have a cumulative frequency of 88. 2%, with the top 512, it reaches 99. 9%. The modern name Hangul was coined by Ju Sigyeong in 1912, han meant great in archaic Korean, and geul is the native Korean word for script. Taken together, then, the meaning is great script, as the word han had also become one way of indicating Korea as a whole the name could also potentially be interpreted as Korean script. Korean 한글 is pronounced, and in English as /ˈhɑːn. ɡʊl/ or /ˈhɑːŋɡʊl/, when used as an English word, it is often rendered without the diacritics, hangul, and it is often capitalized as Hangul, as it appears in many English dictionaries. Hankul in the Yale romanization, a system recommended for technical linguistic studies, North Koreans call it Chosŏngŭl, after Chosŏn, the North Korean name for Korea. Because of objections to the names Hangeul, Chosŏngŭl, and urigeul by Koreans in China, until the early 20th century, Hangul was denigrated as vulgar by the literate elite, who preferred the traditional hanja writing system. They gave it such names as these, Achimgeul, in the original Hanja, it is rendered as 故智者不終朝而會，愚者可浹旬而學。 Gugmun Eonmun Amgeul. Am is a prefix that signifies a noun is feminine Ahaetgeul or Ahaegeul Hangul was promulgated by Sejong the Great, the Hall of Worthies, a group of scholars who worked with Sejong to develop and refine the new alphabet, is often credited for the work. The project was completed in late December 1443 or January 1444, the publication date of the Hunmin Jeong-eum, October 9, became Hangul Day in South Korea. Its North Korean equivalent, Chosongul Day, is on January 15, various speculations about the creation process were put to rest by the discovery in 1940 of the 1446 Hunmin Jeong-eum Haerye. This document explains the design of the consonant letters according to articulatory phonetics, to assuage this problem, King Sejong created the unique alphabet known as Hangul to promote literacy among the common people. However, it entered popular culture as Sejong had intended, being used especially by women, the late 16th century, however, saw a revival of Hangul, with gasa literature and later sijo flourishing. In the 17th century, Hangul novels became a major genre, by this point spelling had become quite irregular

Phonation
–
The term phonation has slightly different meanings depending on the subfield of phonetics. Among some phoneticians, phonation is the process by which the vocal folds produce certain sounds through quasi-periodic vibration and this is the definition used among those who study laryngeal anatomy and physiology and speech production in general. Voiceless and supra-glottal phonations are included under this definition, the phonatory process, or voicing, occurs when air is expelled from the lungs through the glottis, creating a pressure drop across the larynx. When this drop becomes sufficiently large, the vocal folds start to oscillate, the minimum pressure drop required to achieve phonation is called the phonation threshold pressure, and for humans with normal vocal folds, it is approximately 2–3 cm H2O. The motion of the vocal folds during oscillation is mostly lateral, however, there is almost no motion along the length of the vocal folds. The oscillation of the vocal folds serves to modulate the pressure and flow of the air through the larynx, the sound that the larynx produces is a harmonic series. In other words, it consists of a fundamental tone accompanied by harmonic overtones, in linguistics, a phone is called voiceless if there is no phonation during its occurrence. In speech, voiceless phones are associated with folds that are elongated, highly tensed. Fundamental frequency, the main acoustic cue for the percept pitch, large scale changes are accomplished by increasing the tension in the vocal folds through contraction of the cricothyroid muscle. Variation in fundamental frequency is used linguistically to produce intonation and tone, There are currently two main theories as to how vibration of the vocal folds is initiated, the myoelastic theory and the aerodynamic theory. These two theories are not in contention with one another and it is possible that both theories are true and operating simultaneously to initiate and maintain vibration. A third theory, the theory, was in considerable vogue in the 1950s. Pressure builds up again until the cords are pushed apart. The rate at which the open and close—the number of cycles per second—determines the pitch of the phonation. The aerodynamic theory is based on the Bernoulli energy law in fluids, the push occurs during glottal opening, when the glottis is convergent, whereas the pull occurs during glottal closing, when the glottis is divergent. Such an effect causes a transfer of energy from the airflow to the fold tissues which overcomes losses by dissipation. The amount of pressure needed to begin phonation is defined by Titze as the oscillation threshold pressure. During glottal closure, the air flow is cut off until breath pressure pushes the folds apart and this theory states that the frequency of the vocal fold vibration is determined by the chronaxie of the recurrent nerve, and not by breath pressure or muscular tension

Kannada alphabet
–
Several minor languages, such as Tulu, Konkani, Kodava, Sanketi and Beary, also use alphabets based on the Kannada script. The Kannada and Telugu scripts share high mutual intellegibility with each other, other scripts similar to Kannada script are Sinhala script, and Old Peguan script. The Kannada script is an abugida of forty-nine letters, and is written from left to right. The character set is almost identical to that of other Brahmic scripts, consonantal letters imply an inherent vowel. Letters representing consonants are combined to form digraphs when there is no intervening vowel, otherwise, each letter corresponds to a syllable. The letters are classified into three categories, ಸ್ವರ svara, ವ್ಯಂಜನ vyan̄jana, and ಯೋಗವಾಹಕ yōgavāhaka, the Kannada words for a letter of the script are ಅಕ್ಷರ akshara, ಅಕ್ಕರ akkara, and ವರ್ಣ varṇa. Each letter has its own form and sound, providing the visible and audible representations, Kannada is written from left to right. The Kannada script derives from the Old Kannada script, which evolved around 10th century as the continuation of the Kadamba alphabet of the fourth century and this evolved from the ancient Brahmi script of the third century BCE. Over the centuries some changes have made to the Kannada script. These changes consist of, Modification of existing glyphs, In the early Kannada script, however, distinct signs were employed to denote the special consonants viz. the trill ಱ the retroflex lateral ಳ and the retroflex rhotic ೞ found only in South Indian languages, by 5th century. Introduction of new characters, Kannada script includes characters like ಶ, ಷ, ೠ, ఌ, ౡ, ಐ, ಔ, ಅಂ, ಅಃ, the introduction was done so that Sanskrit could be written using the Kannada script. These changes have facilitated the use of the Kannada script for writing many of the literary Indic languages, when a vowel follows a consonant, it is written with a diacritic rather than as a separate letter. The structured consonants are classified according to where the tongue touches the palate of the mouth and are classified accordingly into five structured groups and these consonants are shown here with their IAST transcriptions. See place of articulation for more information on tongue positions, the unstructured consonants are consonants that do not fall into any of the above structures, ಯ, ರ, ಱ, ಲ, ವ, ಶ, ಷ, ಸ, ಹ, ಳ, ೞ. The Kannada script is rich in conjunct consonant clusters, with most consonants having a standard subjoined form, a table of consonant conjuncts follows, although the forms of individual conjuncts may differ according to font. The decimal numerals in the script are, Written Kannada is composed of akshara or kagunita, the letters for consonants combine with diacitics for vowels. The consonant letter without any diacritic, such as ಕ ka, has the inherent vowel a ಅ, a consonant without a vowel is marked with a killer stroke, as ಕ್ k. This is known as hrasva ಹ್ರಸ್ವ, * This diacritic has the form ಿ when combined with other consonant letters

International Phonetic Alphabet
–
The International Phonetic Alphabet is an alphabetic system of phonetic notation based primarily on the Latin alphabet. It was devised by the International Phonetic Association as a representation of the sounds of spoken language. The IPA is used by lexicographers, foreign students and teachers, linguists, speech-language pathologists, singers, actors, constructed language creators. The IPA is designed to represent only those qualities of speech that are part of language, phones, phonemes, intonation. IPA symbols are composed of one or more elements of two types, letters and diacritics. For example, the sound of the English letter ⟨t⟩ may be transcribed in IPA with a letter, or with a letter plus diacritics. Often, slashes are used to signal broad or phonemic transcription, thus, /t/ is less specific than, occasionally letters or diacritics are added, removed, or modified by the International Phonetic Association. As of the most recent change in 2005, there are 107 letters,52 diacritics and these are shown in the current IPA chart, posted below in this article and at the website of the IPA. In 1886, a group of French and British language teachers, led by the French linguist Paul Passy, for example, the sound was originally represented with the letter ⟨c⟩ in English, but with the digraph ⟨ch⟩ in French. However, in 1888, the alphabet was revised so as to be uniform across languages, the idea of making the IPA was first suggested by Otto Jespersen in a letter to Paul Passy. It was developed by Alexander John Ellis, Henry Sweet, Daniel Jones, since its creation, the IPA has undergone a number of revisions. After major revisions and expansions in 1900 and 1932, the IPA remained unchanged until the International Phonetic Association Kiel Convention in 1989, a minor revision took place in 1993 with the addition of four letters for mid central vowels and the removal of letters for voiceless implosives. The alphabet was last revised in May 2005 with the addition of a letter for a labiodental flap, apart from the addition and removal of symbols, changes to the IPA have consisted largely in renaming symbols and categories and in modifying typefaces. Extensions to the International Phonetic Alphabet for speech pathology were created in 1990, the general principle of the IPA is to provide one letter for each distinctive sound, although this practice is not followed if the sound itself is complex. There are no letters that have context-dependent sound values, as do hard, finally, the IPA does not usually have separate letters for two sounds if no known language makes a distinction between them, a property known as selectiveness. These are organized into a chart, the chart displayed here is the chart as posted at the website of the IPA. The letters chosen for the IPA are meant to harmonize with the Latin alphabet, for this reason, most letters are either Latin or Greek, or modifications thereof. Some letters are neither, for example, the letter denoting the glottal stop, ⟨ʔ⟩, has the form of a question mark

Manner of articulation
–
In articulatory phonetics, the manner of articulation is the configuration and interaction of the articulators when making a speech sound. One parameter of manner is stricture, that is, how closely the speech organs approach one another, others include those involved in the r-like sounds, and the sibilancy of fricatives. For consonants, the place of articulation and the degree of phonation of voicing are considered separately from manner, homorganic consonants, which have the same place of articulation, may have different manners of articulation. Often nasality and laterality are included in manner, but some phoneticians, such as Peter Ladefoged, from greatest to least stricture, speech sounds may be classified along a cline as stop consonants, fricative consonants, approximants, and vowels. Affricates often behave as if they were intermediate stops and fricatives, but phonetically they are sequences of a stop and fricative. Over time, sounds in a language may move along this cline toward less stricture in a process called lenition, sibilants are distinguished from other fricatives by the shape of the tongue and how the airflow is directed over the teeth. Fricatives at coronal places of articulation may be sibilant or non-sibilant, taps and flaps are similar to very brief stops. However, their articulation and behavior are enough to be considered a separate manner, rather than just length. Trills involve the vibration of one of the speech organs, since trilling is a separate parameter from stricture, the two may be combined. Increasing the stricture of a typical trill results in a trilled fricative, nasal airflow may be added as an independent parameter to any speech sound. It is most commonly found in nasal occlusives and nasal vowels, but nasalized fricatives, taps, when a sound is not nasal, it is called oral. Laterality is the release of airflow at the side of the tongue and this can be combined with other manners, resulting in lateral approximants, lateral flaps, and lateral fricatives and affricates. Stop, an oral occlusive, where there is occlusion of the vocal tract. Examples include English /p t k/ and /b d ɡ/, if the consonant is voiced, the voicing is the only sound made during occlusion, if it is voiceless, a stop is completely silent. What we hear as a /p/ or /k/ is the effect that the onset of the occlusion has on the vowel, as well as the release burst. The shape and position of the tongue determine the resonant cavity that gives different stops their characteristic sounds, nasal, a nasal occlusive, where there is occlusion of the oral tract, but air passes through the nose. The shape and position of the tongue determine the resonant cavity that gives different nasals their characteristic sounds, nearly all languages have nasals, the only exceptions being in the area of Puget Sound and a single language on Bougainville Island. Fricative, sometimes called spirant, where there is continuous frication at the place of articulation, examples include English /f, s/, /v, z/, etc

French phonology
–
French phonology is the sound system of French. This article discusses mainly the phonology of Standard French of the Parisian dialect, meaning, The window has been left open. /l/ is usually apical alveolar but sometimes laminal denti-alveolar, before /f, ʒ/, it can be realised as retroflex. In current pronunciation, /ɲ/ is merging with /nj/, the velar nasal /ŋ/ is not a native phoneme of French, but it occurs in loan words such as camping, bingo or kung-fu. Some speakers who have difficulty with this consonant realise it as a sequence or replace it with /ɲ/, the approximants /j, ɥ, w/ correspond to the close vowels /i, y, u/. While there are a few pairs, there are many cases where there is free variation. Some dialects of French have a palatal lateral /ʎ/, but in the standard variety. See also Glides and diphthongs, below, the French rhotic has a wide range of realizations, the voiceless or voiced uvular fricatives and, the uvular trill, the alveolar trill, and the alveolar tap. These are all recognized as the phoneme /r/, but all except and are considered dialectal. is the standard consonant, although the voiceless is pronounced before or after a voiceless obstruant or at the end of a sentence, the voiced symbol is often used in phonemic transcriptions. See French guttural r and map at right, the phoneme /x/ is not a native phoneme of French but occurs in loan words such as khamsin, manhua or jota. People who have difficulty with this sound usually replace it with either /ʁ/, some speakers pronounce /k/ and /ɡ/ as and before /i, e, ɛ, a, ɛ̃/ and at the end of a word. Although double consonant letters appear in the form of many French words. The following cases can be identified, the pronunciation is found in the future and conditional forms of the verbs courir and mourir. The conditional form il mourrait, for example, contrasts with the imperfect form il mourait, other verbs that have a double ⟨rr⟩ orthographically in the future and conditional are pronounced with a simple, il pourra, il verra. The pronunciation of words, in many cases, a spelling pronunciation varies by speaker. In particular, the gemination of consonants other than the liquids, examples of stylistically marked pronunciations include addition and intelligence. Gemination of doubled m and n is typical of the Languedoc region, a few cases of gemination do not correspond to double consonant letters in the orthography. The deletion of schwas, for example, can give rise to sequences of identical consonants, là-dedans

Speech
–
Speech is the vocalized form of communication based upon the syntactic combination of lexicals and names that are drawn from very large vocabularies. Each spoken word is created out of the combination of a limited set of vowel. These vocabularies, the syntax that structures them, and their sets of speech sound units differ, creating thousands of different. Most human speakers are able to communicate in two or more of them, hence being polyglots, the vocal abilities that enable humans to produce speech also enable them to sing. A gestural form of human communication exists for the deaf in the form of sign language, speech in some cultures has become the basis of a written language, often one that differs in its vocabulary, syntax and phonetics from its associated spoken one, a situation called diglossia. Speech is researched in terms of the production and speech perception of the sounds used in vocal language. Several academic disciplines study these, including acoustics, psychology, speech pathology, linguistics, cognitive science, communication studies, otolaryngology, another area of research is how the human brain in its different areas such as the Brocas area and Wernickes area underlies speech. It is controversial how far human speech is unique, in animals also communicate with vocalizations. The origins of speech are unknown and subject to much debate, in linguistics, manner of articulation describes how the tongue, lips, jaw, vocal cords, and other speech organs used to produce sounds, make contact with each other. Often the concept is used for the production of consonants. For any place of articulation, there may be several manners of articulation, normal human speech is produced with pressure from the lungs, which creates phonation in the glottis in the larynx, which is then modified by the vocal tract into different vowels and consonants. However humans can pronounce words without the use of the lungs and glottis in alaryngeal speech, speech perception refers to the processes by which humans can interpret and understand the sounds used in language. The study of perception is closely linked to the fields of phonetics and phonology in linguistics and cognitive psychology. Research in speech perception seeks to understand how human listeners recognize speech sounds, speech research has applications in building computer systems that can recognize speech, as well as improving speech recognition for hearing- and language-impaired listeners. Spoken vocalizations are quickly turned from sensory inputs into motor instructions needed for their immediate or delayed vocal imitation and this occurs independently of speech perception. This type of mapping plays a key role in enabling children to expand their spoken vocabulary, speech is a complex activity, as a result, errors are often made in speech. Speech errors have been analyzed by scientists to understand the nature of the involved in the production of speech. There are several organic and psychological factors that can affect speech, among these are, Diseases and disorders of the lungs or the vocal cords, including paralysis, respiratory infections, vocal fold nodules and cancers of the lungs and throat
