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 the speech organs approach one another. Others include those involved in the r-like sounds, the sibilancy of fricatives; the concept of manner is used in the discussion of consonants, although the movement of the articulators will greatly alter the resonant properties of the vocal tract, thereby changing the formant structure of speech sounds, crucial for the identification of vowels. For consonants, the place of articulation and the degree of phonation of voicing are considered separately from manner, as being independent parameters. Homorganic consonants, which have the same place of articulation, may have different manners of articulation. Nasality and laterality are included in manner, but some phoneticians, such as Peter Ladefoged, consider them to be independent. Manners of articulation with substantial obstruction of the airflow are called obstruents.
These are prototypically voiceless, but voiced obstruents are common as well. Manners without such obstruction are called sonorants. Voiceless sonorants are uncommon, but are found in Welsh and Classical Greek, in Standard Tibetan, the "wh" in those dialects of English that distinguish "which" from "witch". Sonorants may be called resonants, some linguists prefer that term, restricting the word'sonorant' to non-vocoid resonants. Another common distinction is between continuants. From greatest to least stricture, speech sounds may be classified along a cline as stop consonants, fricative consonants and vowels. Affricates behave as if they were intermediate between 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, or towards more stricture in a process called fortition. 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, sibilants being the more common. Flaps are similar to brief stops. However, their articulation and behavior are distinct enough to be considered a separate manner, rather than just length; the main articulatory difference between flaps and stops is that, due to the greater length of stops compared to flaps, a build-up of air pressure occurs behind a stop which does not occur behind a flap. This means that when the stop is released, there is a burst of air as the pressure is relieved, while for flaps there is no such burst. 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. Trilled affricates are known. Nasal airflow may be added as an independent parameter to any speech sound, it is most found in nasal occlusives and nasal vowels, but nasalized fricatives and approximants are found.
When a sound is not nasal, it is called oral. Laterality is the release of airflow at the side of the tongue; this can be combined with other manners, resulting in lateral approximants, lateral flaps, lateral fricatives and affricates. Stop, an oral occlusive, where there is occlusion of the oral vocal tract, no nasal air flow, so the air flow stops completely. Examples include English /p t k/ and /b d ɡ/. If the consonant is voiced, the voicing is the only sound made during occlusion. What we hear as a /p/ or /k/ is the effect that the onset of the occlusion has on the preceding vowel, as well as the release burst and its effect on the following vowel; the shape and position of the tongue determine the resonant cavity that gives different stops their characteristic sounds. All languages have stops. 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.
Examples include English /m, n/. 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 etc.. Most languages have fricatives, though many have only an /s/. However, the Indigenous Australian languages are completely devoid of fricatives of any kind. Sibilants are a type of fricative where the airflow is guided by a groove in the tongue toward the teeth, creating a high-pitched and distinctive sound; these are by far the most common fricatives. Fricatives at coronal places of articulation are though not always, sibilants. English sibilants include /s/ and /z/. Lateral fricatives are a rare type of fricative, where the frication occurs on one or both sides of the edge of th
The term phonation has 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; this is the definition used among those who study laryngeal anatomy and physiology and speech production in general. Phoneticians in other subfields, such as linguistic phonetics, call this process voicing, use the term phonation to refer to any oscillatory state of any part of the larynx that modifies the airstream, of which voicing is just one example. 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, for humans with normal vocal folds, it is 2–3 cm H2O.
The motion of the vocal folds during oscillation is lateral, though there is some superior component as well. However, there is 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, this modulated airflow is the main component of the sound of most voiced phones. The sound that the larynx produces is a harmonic series. In other words, it consists of a fundamental tone accompanied by harmonic overtones, which are multiples of the fundamental frequency. According to the source–filter theory, the resulting sound excites the resonance chamber, the vocal tract to produce the individual speech sounds; the vocal folds will not oscillate if they are not sufficiently close to one another, are not under sufficient tension or under too much tension, or if the pressure drop across the larynx is not sufficiently large. In linguistics, a phone is called voiceless. In speech, voiceless phones are associated with vocal folds that are elongated tensed, placed laterally when compared to vocal folds during phonation.
Fundamental frequency, the main acoustic cue for the percept pitch, can be varied through a variety of means. Large scale changes are accomplished by increasing the tension in the vocal folds through contraction of the cricothyroid muscle. Smaller changes in tension can be effected by contraction of the thyroarytenoid muscle or changes in the relative position of the thyroid and cricoid cartilages, as may occur when the larynx is lowered or raised, either volitionally or through movement of the tongue to which the larynx is attached via the hyoid bone. In addition to tension changes, fundamental frequency is affected by the pressure drop across the larynx, affected by the pressure in the lungs, will vary with the distance between the vocal folds. Variation in fundamental frequency is used linguistically to produce tone. There are 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 quite possible that both theories are true and operating to initiate and maintain vibration.
A third theory, the neurochronaxic theory, was in considerable vogue in the 1950s, but has since been discredited. The myoelastic theory states that when the vocal cords are brought together and breath pressure is applied to them, the cords remain closed until the pressure beneath them, the subglottic pressure, is sufficient to push them apart, allowing air to escape and reducing the pressure enough for the muscle tension recoil to pull the folds back together again; the pressure builds up once again until the cords are pushed apart, the whole cycle keeps repeating itself. The rate at which the cords 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 theory states that when a stream of breath is flowing through the glottis while the arytenoid cartilages are held together, a push-pull effect is created on the vocal fold tissues that maintains self-sustained oscillation; the push occurs during glottal opening, when the glottis is convergent, the pull occurs during glottal closing, when the glottis is divergent.
Such an effect causes a transfer of energy from the airflow to the vocal fold tissues which overcomes losses by dissipation and sustain the oscillation. The amount of lung 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 the flow starts up again, causing the cycles to repeat; the textbook entitled Myoelastic Aerodynamic Theory of Phonation by Ingo Titze credits Janwillem van den Berg as the originator of the theory and provides detailed mathematical development of the theory. This theory states that the frequency of the vocal fold vibration is determined by the chronaxie of the recurrent nerve, not by breath pressure or muscular tension. Advocates of this theory thought that every single vibration of the vocal folds was due to an impulse from the recurrent laryngeal nerves and that the acoustic center in the brain regulated the speed of vocal fold vibration.
Speech and voice scientists have long since left this theory as the muscles have been shown to not be able to contract fast enough to accomplish the vibration. In addition, persons with paralyzed vocal folds can produce phonation, whic
Cantonese is a variety of Chinese spoken in the city of Guangzhou and its surrounding area in Southeastern China. It is the traditional prestige variety and standard form of Yue Chinese, one of the major subgroups of Chinese. In mainland China, it is the lingua franca of the province of Guangdong and neighbouring areas such as Guangxi, it is the official language of Hong Kong and Macau. Cantonese is widely spoken amongst Overseas Chinese in Southeast Asia and throughout the Western world. While the term Cantonese refers to the prestige variety, it is used in a broader sense for the entire Yue subgroup of Chinese, including related but mutually unintelligible languages and dialects such as Taishanese; when Cantonese and the related Yuehai dialects are classified together, there are about 80 million total speakers. Cantonese is viewed as a vital and inseparable part of the cultural identity for its native speakers across large swaths of Southeastern China, Hong Kong and Macau, as well as in overseas communities.
Although Cantonese shares a lot of vocabulary with Mandarin, the two varieties are mutually unintelligible because of differences in pronunciation and lexicon. Sentence structure, in particular the placement of verbs, sometimes differs between the two varieties. A notable difference between Cantonese and Mandarin is; this results in the situation in which a Cantonese and a Mandarin text may look similar but are pronounced differently. In English, the term "Cantonese" can be ambiguous. Cantonese proper is the variety native to the city of Canton, the traditional English name of Guangzhou; this narrow sense may be specified as "Canton language" or "Guangzhou language". However, "Cantonese" may refer to the primary branch of Chinese that contains Cantonese proper as well as Taishanese and Gaoyang. In this article, "Cantonese" is used for Cantonese proper. Speakers called this variety "Canton speech" or "Guangzhou speech", although this term is now used outside Guangzhou. In Guangdong and Guangxi, people call it "provincial capital speech" or "plain speech".
Academically called "Canton prefecture speech". In Hong Kong and Macau, as well as among overseas Chinese communities, the language is referred to as "Guangdong speech" or "Canton Province speech", or as "Chinese". In mainland China, the term "Guangdong speech" is increasingly being used amongst both native and non-native speakers. Given the history of the development of the Yue languages and dialects during the Tang dynasty migrations to the region, in overseas Chinese communities, it is referred to as "Tang speech", given that the Cantonese people refer to themselves as "people of Tang". Due to its status as a prestige dialect among all the dialects of the Yue branch of Chinese varieties, it is called "Standard Cantonese"; the official languages of Hong Kong are English, as defined in the Hong Kong Basic Law. The Chinese language has many different varieties. Given the traditional predominance of Cantonese within Hong Kong, it is the de facto official spoken form of the Chinese language used in the Hong Kong Government and all courts and tribunals.
It is used as the medium of instruction in schools, alongside English. A similar situation exists in neighboring Macau, where Chinese is an official language alongside Portuguese; as in Hong Kong, Cantonese is the predominant spoken variety of Chinese used in everyday life and is thus the official form of Chinese used in the government. The Cantonese spoken in Hong Kong and Macau is mutually intelligible with the Cantonese spoken in the mainland city of Guangzhou, although there exist some minor differences in accent and vocabulary. Cantonese first developed around the port city of Guangzhou in the Pearl River Delta region of southeastern China. Due to the city's long standing as an important cultural center, Cantonese emerged as the prestige dialect of the Yue varieties of Chinese in the Southern Song dynasty and its usage spread around most of what is now the provinces of Guangdong and Guangxi. Despite the cession of Macau to Portugal in 1557 and Hong Kong to Britain in 1842, the ethnic Chinese population of the two territories originated from the 19th and 20th century immigration from Guangzhou and surrounding areas, making Cantonese the predominant Chinese language in the territories.
On the mainland, Cantonese continued to serve as the lingua franca of Guangdong and Guangxi provinces after Mandarin was made the official language of the government by the Qing dynasty in the early 1900s. Cantonese remained a dominant and influential language in southeastern China until the establishment of the People's Republic of China in 1949 and its promotion of Standard Chinese as the sole official language of the nation throughout the last half of the 20th century, although its influence still remains strong within the region. While the Chinese government vehemently discourages the official use of all forms of Chinese except Standard Chinese, Cantonese enjoys a higher standing than other Chinese langua
International Phonetic Alphabet
The International Phonetic Alphabet is an alphabetic system of phonetic notation based on the Latin alphabet. It was devised by the International Phonetic Association in the late 19th century as a standardized representation of the sounds of spoken language; the IPA is used by lexicographers, foreign language students and teachers, speech-language pathologists, actors, constructed language creators and translators. The IPA is designed to represent only those qualities of speech that are part of oral language: phones, phonemes and the separation of words and syllables. To represent additional qualities of speech, such as tooth gnashing and sounds made with a cleft lip and cleft palate, an extended set of symbols, the extensions to the International Phonetic Alphabet, may be used. IPA symbols are composed of one or more elements of two basic types and diacritics. For example, the sound of the English letter ⟨t⟩ may be transcribed in IPA with a single letter, or with a letter plus diacritics, depending on how precise one wishes to be.
Slashes are used to signal broad or phonemic transcription. 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 four prosodic marks in the IPA. 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, formed what would come to be known from 1897 onwards as the International Phonetic Association, their original alphabet was based on a spelling reform for English known as the Romic alphabet, but in order to make it usable for other languages, the values of the symbols were allowed to vary from language to language. For example, the sound was 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, thus providing the base for all future revisions.
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, Passy. Since its creation, the IPA has undergone a number of revisions. After revisions and expansions from the 1890s to the 1940s, the IPA remained unchanged until the 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 of renaming symbols and categories and in modifying typefaces. Extensions to the International Phonetic Alphabet for speech pathology were created in 1990 and adopted by the International Clinical Phonetics and Linguistics Association in 1994; 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.
This means that: It does not use combinations of letters to represent single sounds, the way English does with ⟨sh⟩, ⟨th⟩ and ⟨ng⟩, or single letters to represent multiple sounds the way ⟨x⟩ represents /ks/ or /ɡz/ in English. There are no letters that have context-dependent sound values, as do "hard" and "soft" ⟨c⟩ or ⟨g⟩ in several European languages; the IPA does not have separate letters for two sounds if no known language makes a distinction between them, a property known as "selectiveness". Among the symbols of the IPA, 107 letters represent consonants and vowels, 31 diacritics are used to modify these, 19 additional signs indicate suprasegmental qualities such as length, tone and intonation; these are organized into a chart. The letters chosen for the IPA are meant to harmonize with the Latin alphabet. For this reason, most letters modifications thereof; some letters are neither: for example, the letter denoting the glottal stop, ⟨ʔ⟩, has the form of a dotless question mark, derives from an apostrophe.
A few letters, such as that of the voiced pharyngeal fricative, ⟨ʕ⟩, were inspired by other writing systems. Despite its preference for harmonizing with the Latin script, the International Phonetic Association has admitted other letters. For example, before 1989, the IPA letters for click consonants were ⟨ʘ⟩, ⟨ʇ⟩, ⟨ʗ⟩, ⟨ʖ⟩, all of which were derived either from existing IPA letters, or from Latin and Greek letters. However, except for ⟨ʘ⟩, none of these letters were used among Khoisanists or Bantuists, as a result they were replaced by the more widespread symbols ⟨ʘ⟩, ⟨ǀ⟩, ⟨ǃ⟩, ⟨ǂ⟩, ⟨ǁ⟩ at the IPA Kiel Convention in 1989. Although the IPA diacritics are featural, there is little systemicity in the letter forms. A retroflex articulation is indicated with a right-swinging tail, as in ⟨ɖ ʂ ɳ⟩, implosion by a top hook, ⟨ɓ ɗ ɠ⟩, but other pseudo-featural elements are due to haphazard derivation and coincidence. For example, all nasal consonants but uvular ⟨ɴ⟩ are based on the form ⟨n⟩: ⟨m ɱ n ɳ ɲ ŋ⟩.
However, the similarity between ⟨m⟩ and ⟨n⟩ is a historical accident. Some of the new letters were ordinary Latin letters tu
The Arabian peninsula, simplified Arabia, is a peninsula of Western Asia situated northeast of Africa on the Arabian plate. From a geographical perspective, it is considered a subcontinent of Asia, it is the largest peninsula in the world, at 3,237,500 km2. The peninsula consists of the countries Yemen, Qatar, Kuwait, Saudi Arabia and the United Arab Emirates; the peninsula formed as a result of the rifting of the Red Sea between 56 and 23 million years ago, is bordered by the Red Sea to the west and southwest, the Persian Gulf to the northeast, the Levant to the north and the Indian Ocean to the southeast. The peninsula plays a critical geopolitical role in the Arab world due to its vast reserves of oil and natural gas. Before the modern era, it was divided into four distinct regions: Hejaz, Southern Arabia and Eastern Arabia. Hejaz and Najd make up most of Saudi Arabia. Southern Arabia consists of some parts of Saudi Arabia and Oman. Eastern Arabia consists of the entire coastal strip of the Persian Gulf.
The Arabian Peninsula is located in the continent of Asia and bounded by the Persian Gulf on the northeast, the Strait of Hormuz and the Gulf of Oman on the east, the Arabian Sea on the southeast and south, the Gulf of Aden on the south, the Bab-el-Mandeb strait on the southwest and the Red Sea, located on the southwest and west. The northern portion of the peninsula merges with the Syrian Desert with no clear border line, although the northern boundary of the peninsula is considered to be the northern borders of Saudi Arabia and Kuwait; the most prominent feature of the peninsula is desert, but in the southwest there are mountain ranges, which receive greater rainfall than the rest of the peninsula. Harrat ash Shaam is a large volcanic field that extends from the northwestern Arabia into Jordan and southern Syria; the peninsula's constituent countries are Kuwait, Bahrain and the United Arab Emirates on the east, Oman on the southeast, Yemen on the south and Saudi Arabia at the center. The island nation of Bahrain lies off the east coast of the peninsula.
Six countries form the Gulf Cooperation Council. The Kingdom of Saudi Arabia covers the greater part of the peninsula; the majority of the population of the peninsula live in Yemen. The peninsula contains the world's largest reserves of oil. Saudi Arabia and the UAE are economically the wealthiest in the region. Qatar, a small peninsula in the Persian Gulf on the larger peninsula, is home of the Arabic-language television station Al Jazeera and its English-language subsidiary Al Jazeera English. Kuwait, on the border with Iraq, is an important country strategically, forming one of the main staging grounds for coalition forces mounting the invasion of Iraq in 2003. Though lightly populated, political Arabia is noted for a high population growth rate – as the result of both strong inflows of migrant labor as well as sustained high birth rates; the population tends to be young and skewed gender ratio dominated by males. In many states, the number of South Asians exceeds that of the local citizenry.
The four smallest states, which have their entire coastlines on the Persian Gulf, exhibit the world's most extreme population growth tripling every 20 years. In 2014, the estimated population of the Arabian Peninsula was 77,983,936; the Arabian Peninsula is known for having one of the most uneven adult sex ratios in the world with females in some regions constituting only a quarter of vicenarians and tricenarians. Listed here are the human Y-chromosome DNA haplogroups in Arabia Haplogroup J is the most abundant component in the Arabian peninsula, embracing more than 50% of its Y-chromosomes, its two main subclades, show opposite latitudinal gradients in the Middle East. J1-M267 is more abundant in the southern areas, reaching a frequency around 73% in Yemen, whereas J2-M172 is more common in the Levant. J Accounts for the majority of in Saudi Arabia, it seems to be an Adnani marker. Haplogroup J 54.8% Haplogroup E 17.5% R 11.6% Haplogroup T-M184 5.1% Geologically, this region is more appropriately called the Arabian subcontinent because it lies on a tectonic plate of its own, the Arabian Plate, moving incrementally away from the rest of Africa and north, toward Asia, into the Eurasian Plate.
The rocks exposed vary systematically across Arabia, with the oldest rocks exposed in the Arabian-Nubian Shield near the Red Sea, overlain by earlier sediments that become younger towards the Persian Gulf. The best-preserved ophiolite on Earth, the Semail Ophiolite, lies exposed in the mountains of the UAE and northern Oman; the peninsula consists of: A central plateau, the Najd, with fertile valleys and pastures used for the grazing of sheep and other livestock A range of deserts: the Nefud in the north, stony.
Chinese characters are logograms developed for the writing of Chinese. They have been adapted to write a number of other Asian languages, they remain a key component of the Japanese writing system and are used in the writing of Korean. They were used in Vietnamese and Zhuang. Collectively, they are known as CJK characters. Vietnamese is sometimes included, making the abbreviation CJKV. Chinese characters constitute. By virtue of their widespread current use in East Asia, historic use throughout the Sinosphere, Chinese characters are among the most adopted writing systems in the world by number of users. Chinese characters number in the tens of thousands, though most of them are minor graphic variants encountered only in historical texts. Studies in China have shown that functional literacy in written Chinese requires a knowledge of between three and four thousand characters. In Japan, 2,136 are taught through secondary school. Due to post-WWII simplifications of Kanji in Japan as well as the post-WWII simplifications of characters in China, the Chinese characters used in Japan today are distinct from those used in China in several respects.
There are various national standard lists of characters and pronunciations. Simplified forms of certain characters are used in mainland China and Malaysia. In Japan, common characters are written in post-WWII Japan-specific simplified forms, while uncommon characters are written in Japanese traditional forms, which are identical to Chinese traditional forms. In South Korea, when Chinese characters are used, they are in traditional form identical to those used in Taiwan and Hong Kong where the official writing system is traditional Chinese. Teaching of Chinese characters in South Korea starts in the 7th grade and continues until the 12th grade. In Old Chinese including Classical Chinese, most words were monosyllabic and there was a close correspondence between characters and words. In modern Chinese, the majority of Chinese words today consist of two or more characters. Rather, a character always corresponds to a single syllable, a morpheme. However, there are a few exceptions to this general correspondence, including bisyllabic morphemes, bimorphemic syllables and cases where a single character represents a polysyllabic word or phrase.
Modern Chinese has many homophones. A single character may have a range of meanings, or sometimes quite distinct meanings. Cognates in the several varieties of Chinese are written with the same character, they have similar meanings, but quite different pronunciations. In other languages, most today in Japanese and sometimes in Korean, characters are used to represent Chinese loanwords, to represent native words independently of the Chinese pronunciation, as purely phonetic elements based on their pronunciation in the historical variety of Chinese from which they were acquired; these foreign adaptations of Chinese pronunciation are known as Sino-Xenic pronunciations and have been useful in the reconstruction of Middle Chinese. When the script was first used in the late 2nd millennium BC, words of Old Chinese were monosyllabic, each character denoted a single word. Increasing numbers of polysyllabic words have entered the language from the Western Zhou period to the present day, it is estimated that about 25–30% of the vocabulary of classic texts from the Warring States period was polysyllabic, though these words were used far less than monosyllables, which accounted for 80–90% of occurrences in these texts.
The process has accelerated over the centuries as phonetic change has increased the number of homophones. It has been estimated that over two thirds of the 3,000 most common words in modern Standard Chinese are polysyllables, the vast majority of those being disyllables; the most common process has been to form compounds of existing words, written with the characters of the constituent words. Words have been created by adding affixes and borrowing from other languages. Polysyllabic words are written with one character per syllable. In most cases the character denotes. Many characters have multiple readings, with instances denoting different morphemes, sometimes with different pronunciations. In modern Standard Chinese, one fifth of the 2,400 most common characters have multiple pronunciations. For the 500 most common characters, the proportion rises to 30%; these readings are similar in sound and related in meaning. In the Old Chinese period, affixes could be added to a word to form a new word, written with the same character.
In many cases the pronunciations diverged due to subsequent sound change. For example, many additional readings have the Middle Chinese departing tone, the major sour
Labialization is a secondary articulatory feature of sounds in some languages. Labialized sounds involve the lips; the term is restricted to consonants. When vowels involve the lips, they are called rounded; the most common labialized consonants are labialized velars. Most other labialized sounds have simultaneous velarization, the process may be more called labio-velarization. In phonology, labialization may refer to a type of assimilation process. Labialization is the most widespread secondary articulation in the world's languages, it is phonemically contrastive in Northwest Caucasian and Salishan language families, among others. This contrast is reconstructed for Proto-Indo-European, the common ancestor of the Indo-European languages. American English has three degrees of labialization: tight rounded, slight rounded, unrounded, which in vowels is sometimes called'spread'; these secondary articulations are not universal. For example, French shares the English slight rounding of /ʃ/, /ʒ/ while Russian does not have slight rounding in its postalveolar fricatives.
A few languages, including Arrernte and Mba, have contrastive labialized forms for all of their consonants. Out of 706 language inventories surveyed by Ruhlen, labialization occurred most with velar and uvular segments and least with dental and alveolar segments. With non-dorsal consonants, labialization may include velarization as well. Labialization is not restricted to lip-rounding; the following articulations have either been described as labialization, or been found as allophonic realizations of prototypical labialization: Labiodental frication, found in Abkhaz Complete bilabial closure, found in Abkhaz and Ubykh "Labialization" without noticeable rounding of the lips, found in the Iroquoian languages. It may be. Rounding without velarization, found in Shona and in the Bzyb dialect of Abkhaz. Eastern Arrernte has labialization at all manners of articulation. Marshallese has labialization at all places of articulation except for coronal obstruents. In North America, languages from a number of families have sounds that sound labialized without participation of the lips.
See Tillamook language for an example. In the International Phonetic Alphabet, labialization of velar consonants is indicated with a raised w modifier, as in /kʷ/. There are diacritics to indicate greater or lesser degrees of rounding; these are used with vowels, but may occur with consonants. For example, in the Athabaskan language Hupa, voiceless velar fricatives distinguish three degrees of labialization, transcribed either /x/, /x̹/, /xʷ/ or /x/, /x̜ʷ/, /xʷ/; the extensions to the IPA has two additional symbols for degrees of rounding: Spread and open-rounded. It has a symbol for labiodentalized sounds. If precision is desired, the Abkhaz and Ubykh articulations may be transcribed with the appropriate fricative or trill raised as a diacritic:. For simple labialization, Ladefoged & Maddieson resurrected an old IPA symbol, which would be placed above a letter with a descender such as ɡ. However, their chief example is Shona sv and zv, which they transcribe /s̫/ and /z̫/ but which seem to be whistled sibilants, without being labialized.
Another possibility is to use the IPA diacritic for rounding, distinguishing for example the labialization in English soon and swoon. The open rounding of English /ʃ/ is unvelarized. Labialization refers to a specific type of assimilatory process where a given sound become labialized due to the influence of neighboring labial sounds. For example, /k/ may become /kʷ/ in the environment of /o/, or /a/ may become /o/ in the environment of /p/ or /kʷ/. In the Northwest Caucasian languages as well as some Australian languages rounding has shifted from the vowels to the consonants, producing a wide range of labialized consonants and leaving in some cases only two phonemic vowels; this appears to have been the case in Eastern Arrernte, for example. The labial vowel sounds still remain, but only as allophones next to the now-labial consonant sounds.
