Roundedness
–
In phonetics, vowel roundedness refers to the amount of rounding in the lips during the articulation of a vowel. It is labialization of a vowel, when a rounded vowel is pronounced, the lips form a circular opening, and unrounded vowels are pronounced with the lips relaxed. In most languages, front vowels tend to be unrounded, in the International Phonetic Alphabet vowel chart, rounded vowels are the ones that appear on the right in each pair of vowels. There are also diacritics, U+0339 ̹ COMBINING RIGHT HALF RING BELOW and U+031C ̜ COMBINING LEFT HALF RING BELOW, to greater and lesser degrees of rounding. The more and less rounded diacritics are also used with consonants to indicate degrees of labialization. There are two types of rounding, protrusion and compression. In protruded rounding, the corners of the mouth are drawn together, in compressed rounding, the corners of the mouth are drawn together, but the lips are also drawn together horizontally and do not protrude, with only their outer surface visible. That is, in protruded vowels the inner surfaces of the form the opening. Catford observes that back and central rounded vowels, such as German /o/ and /u/, are typically protruded, whereas front rounded vowels such as German /ø/ and /y/ are typically compressed. Back or central compressed vowels and front protruded vowels are uncommon, there are no dedicated IPA diacritics to represent the distinction, but the superscript IPA letter ⟨◌ᵝ⟩ can be used for compression and ⟨◌ʷ⟩, ⟨◌ᶣ⟩ or ⟨◌̫⟩ for protrusion. Compressed vowels may be pronounced either with the corners of the mouth drawn in, by some definitions rounded, or with the spread and, by the same definitions. The distinction may be transcribed ⟨ɨᵝ ɯᵝ⟩ and ⟨ʉᵝ uᵝ⟩, the distinction between protruded and compressed holds for the semivowels and as well as labialization. In Akan, for example, the is compressed, as are labio-palatalized consonants as in Twi Twi and adwuma work, whereas, in Japanese, the /w/ is compressed rather than protruded, paralleling the Japanese /u/. The distinction applies marginally to other consonants, some vowels transcribed with rounded IPA letters may not be rounded at all. An example is /ɒ/, which in English has very little if any rounding of the lips, the throaty sound of English /ɒ/ is instead accomplished with sulcalization, a furrowing of the back of the tongue also found in non-rhotic /ɜː/. It is possible to mimic the effect of rounded vowels by narrowing the cheeks, so-called cheek rounding. The technique is used by ventriloquists to mask the visible rounding of back vowels like and it is not clear if it is used by languages with rounded vowels that do not use visible rounding. Protruded rounding is the equivalent of consonantal labialization

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

Microsoft Windows
–
Microsoft Windows is a metafamily of graphical operating systems developed, marketed, and sold by Microsoft. It consists of families of operating systems, each of which cater to a certain sector of the computing industry with the OS typically associated with IBM PC compatible architecture. Active Windows families include Windows NT, Windows Embedded and Windows Phone, defunct Windows families include Windows 9x, Windows 10 Mobile is an active product, unrelated to the defunct family Windows Mobile. Microsoft introduced an operating environment named Windows on November 20,1985, Microsoft Windows came to dominate the worlds personal computer market with over 90% market share, overtaking Mac OS, which had been introduced in 1984. Apple came to see Windows as an encroachment on their innovation in GUI development as implemented on products such as the Lisa. On PCs, Windows is still the most popular operating system, however, in 2014, Microsoft admitted losing the majority of the overall operating system market to Android, because of the massive growth in sales of Android smartphones. In 2014, the number of Windows devices sold was less than 25% that of Android devices sold and this comparison however may not be fully relevant, as the two operating systems traditionally target different platforms. As of September 2016, the most recent version of Windows for PCs, tablets, smartphones, the most recent versions for server computers is Windows Server 2016. A specialized version of Windows runs on the Xbox One game console, Microsoft, the developer of Windows, has registered several trademarks each of which denote a family of Windows operating systems that target a specific sector of the computing industry. It now consists of three operating system subfamilies that are released almost at the time and share the same kernel. Windows, The operating system for personal computers, tablets. The latest version is Windows 10, the main competitor of this family is macOS by Apple Inc. for personal computers and Android for mobile devices. Windows Server, The operating system for server computers, the latest version is Windows Server 2016. Unlike its clients sibling, it has adopted a strong naming scheme, the main competitor of this family is Linux. Windows PE, A lightweight version of its Windows sibling meant to operate as an operating system, used for installing Windows on bare-metal computers. The latest version is Windows PE10.0.10586.0, Windows Embedded, Initially, Microsoft developed Windows CE as a general-purpose operating system for every device that was too resource-limited to be called a full-fledged computer. The following Windows families are no longer being developed, Windows 9x, Microsoft now caters to the consumers market with Windows NT. Windows Mobile, The predecessor to Windows Phone, it was a mobile operating system

Vowel
–
In phonetics, a vowel is a sound in spoken language, with two competing definitions. There is no build-up of air pressure at any point above the glottis and this contrasts with consonants, such as the English sh, which have a constriction or closure at some point along the vocal tract. In the other, phonological definition, a vowel is defined as syllabic, a phonetically equivalent but non-syllabic sound is a semivowel. In oral languages, phonetic vowels normally form the peak of many to all syllables, whereas consonants form the onset and coda. Some languages allow other sounds to form the nucleus of a syllable, the word vowel comes from the Latin word vocalis, meaning vocal. In English, the vowel is commonly used to mean both vowel sounds and the written symbols that represent them. The phonetic definition of vowel does not always match the phonological definition, the approximants and illustrate this, both are produced without much of a constriction in the vocal tract, but they occur at the onset of syllables. A similar debate arises over whether a word like bird in a dialect has an r-colored vowel /ɝ/ or a syllabic consonant /ɹ̩/. The American linguist Kenneth Pike suggested the terms vocoid for a vowel and vowel for a phonological vowel, so using this terminology. Nonetheless, the phonetic and phonemic definitions would still conflict for the syllabic el in table, or the syllabic nasals in button, daniel Jones developed the cardinal vowel system to describe vowels in terms of the features of tongue height, tongue backness and roundedness. These three parameters are indicated in the schematic quadrilateral IPA vowel diagram on the right, there are additional features of vowel quality, such as the velum position, type of vocal fold vibration, and tongue root position. This conception of vowel articulation has been known to be inaccurate since 1928, Peter Ladefoged has said that early phoneticians. Thought they were describing the highest point of the tongue, and they were actually describing formant frequencies. The IPA Handbook concedes that the quadrilateral must be regarded as an abstraction. Vowel height is named for the position of the tongue relative to either the roof of the mouth or the aperture of the jaw. However, it refers to the first formant, abbreviated F1. Height is defined by the inverse of the F1 value, The higher the frequency of the first formant, however, if more precision is required, true-mid vowels may be written with a lowering diacritic. Although English contrasts six heights in its vowels, they are interdependent with differences in backness and it appears that some varieties of German have five contrasting vowel heights independently of length or other parameters

Close-mid back unrounded vowel
–
The close-mid back unrounded vowel, or high-mid back unrounded vowel, is a type of vowel sound, used in some spoken languages. Acoustically it is a close-mid back-central unrounded vowel and its symbol in the International Phonetic Alphabet is ⟨ɤ⟩, called rams horns. It is distinct from the symbol for the velar fricative, ⟨ɣ⟩. Despite that, some use this symbol for the voiced velar fricative. The IPA prefers terms close and open for vowels, and the name of the article follows this, however, a large number of linguists, perhaps a majority, prefer the terms high and low. Before the 1989 IPA Convention, the symbol for the close-mid back unrounded vowel was ⟨⟩, sometimes called baby gamma, the symbol was revised to be ⟨⟩, rams horns, with a rounded top, in order to better differentiate it from the Latin gamma ⟨ɣ⟩. Unicode provides only U+0264 ɤ LATIN SMALL LETTER RAMS HORN, and its vowel height is close-mid, also known as high-mid, which means the tongue is positioned halfway between a close vowel and a mid vowel. Its vowel backness is back, which means the tongue is positioned as far back as possible in the mouth without creating a constriction that would be classified as a consonant, note that unrounded back vowels tend to be centralized, which means that often they are in fact near-back. It is unrounded, which means that the lips are not rounded

X-SAMPA
–
The Extended Speech Assessment Methods Phonetic Alphabet is a variant of SAMPA developed in 1995 by John C. Wells, professor of phonetics at the University of London and it is designed to unify the individual language SAMPA alphabets, and extend SAMPA to cover the entire range of characters in the International Phonetic Alphabet. The result is a SAMPA-inspired remapping of the IPA into 7-bit ASCII, SAMPA was devised as a hack to work around the inability of text encodings to represent IPA symbols. Later, as Unicode support for IPA symbols became more widespread, however, X-SAMPA is still useful as the basis for an input method for true IPA. The IPA symbols that are ordinary lower-case letters have the value in X-SAMPA as they do in the IPA. X-SAMPA uses backslashes as modifying suffixes to create new symbols, for example, O is a distinct sound from O\, to which it bears no relation. Such use of the character can be a problem, since many programs interpret it as an escape character for the character following it. For example, you use such X-SAMPA symbols in EMU. X-SAMPA diacritics follow the symbols they modify, except for ~ for nasalization, = for syllabicity, and for retroflexion and rhotacization, diacritics are joined to the character with the underscore character _. The underscore character is used to encode the IPA tiebar. The numbers _1 to _6 are reserved diacritics as shorthand for language-specific tone numbers, asterisks mark sounds that do not have X-SAMPA symbols. Daggers mark IPA symbols that have recently added to Unicode. Since April 2008, the latter is the case of the labiodental flap, a dedicated symbol for the labiodental flap does not yet exist in X-SAMPA.

IPA Braille
–
IPA Braille is the modern standard Braille encoding of the International Phonetic Alphabet, as recognized by the International Council on English Braille. A braille version of the IPA was first created by Merrick and Potthoff in 1934 and it was used in France, Germany, and anglophone countries. However, it was not updated as the IPA evolved, in 1990 it was officially reissued by BAUK, but in a corrupted form that made it largely unworkable. In 1997 BANA created a new system for the United States. However, it was incompatible with braille IPA elsewhere in the world and in addition proved to be cumbersome, in 2008 Robert Englebretson revised the Merrick and Potthoff notation and by 2011 this had been accepted by BANA. It is largely true to the original in consonants and vowels, though the diacritics were completely reworked, the diacritics were also made more systematic, and follow rather than precede the base letters. However, it has no procedure for marking tone. IPA Braille does not use the conventions of English Braille and it is set off by slash or square brackets, which indicate that the intervening material is IPA rather than national orthography. Thus brackets are required in braille even when not used in print, the choice for ⟨ɹ⟩ may reflect the shape of that letter in print. Many of the vowels are used for modified vowels in national alphabets, a few other letters such as ⠹ occur, but only as parts of digraphs. Other IPA letters are indicated with digraphs or even trigraphs usinɡ 5th-decade letters, the component letter ⠲. for example, is equivalent to the tail of the retroflex consonants. This presumably derives from the old IPA practice of using a dot for retroflex consonants. It also marks vowels which in print are formed by rotating the letter, is treated as a rotated ⟨o⟩, and ⟨ɯ⟩ as a rotated ⟨u⟩ rather than ⟨m⟩, perhaps facilitated by braille ⟨u⟩ and ⟨m⟩ themselves being a rotated pair. The basic braille letters ⠹ and ⠯, which do not occur on their own in IPA usage, ⠨ is also used with letters of the fifth decade for transcriber-defined symbols, which need to be specified for each text, as they have no set meaning. These are ⠨⠂, ⠨⠆, ⠨⠒, ⠨⠲, ⠨⠢, ⠨⠖, ⠨⠶, ⠨⠦, ⠨⠔, ⠨⠴. ⠴ is used for barred vowels. ⠖ is used for other hooks, as in flaps, ⠯ is used for click letters. These are far more legible in braille than in print, ligatures, regardless of whether these are written with a tie bar or as actual ligatures in print, are indicated by dot 5, so ⟨t͜ʃ⟩ and ⟨ʧ⟩ are both ⠞⠐⠱. This includes the historic ligatures ⟨ɮ⟩ ⠇⠐⠮ and ⟨ɚ⟩ ⠢⠐⠗, ejectives are written as ligatures with an apostrophe, ⠄, so ⟨tʼ⟩ is ⠞⠐⠄. IPA Braille diacritics are written in two cells, the first indicates the position, whether superscript, mid-line, or subscript

Schwa
–
In linguistics, specifically phonetics and phonology, schwa is the mid central vowel sound in the middle of the vowel chart, denoted by the IPA symbol ə, or another vowel sound close to that position. An example in English is the sound of the a in the word about. Schwa in English is mainly found in unstressed positions, but in other languages it occurs more frequently as a stressed vowel. In relation to languages, the name schwa and the symbol ə may be used for some other unstressed and toneless neutral vowel. The word schwa is from the Hebrew word shva, designating the Hebrew niqqud vowel sign shva, in Modern Hebrew, the term was introduced into European linguistics by Jacob Grimm in the early 19th century, and so the spelling sch is German in origin. It was first used in English texts between 1890 and 1895, the symbol ⟨ə⟩ was used first by Johann Andreas Schmeller for the reduced vowel at the end of the German name Gabe. Alexander John Ellis, in his alphabet, used it for the similar English sound in. Sometimes the term schwa is used for any vowel. In English, schwa is the most common vowel sound and it is a reduced vowel in many unstressed syllables especially if syllabic consonants are not used. In most varieties of English, schwa occurs almost exclusively in unstressed syllables, in New Zealand English, the high front lax vowel has shifted open and back to sound like schwa, and both stressed and unstressed schwas exist. To a certain extent, that is true for South African English as well, in General American, schwa and ɜː are the two vowel sounds that can be r-colored, r-colored schwa is used in words with unstressed er syllables, such as dinner. See also stress and vowel reduction in English, quite a few languages have a sound similar to schwa. It is similar to a short French unaccented ⟨e⟩, which is rounded and less central and it is almost always unstressed, but Albanian, Bulgarian, Slovene and Afrikaans are some of the languages that allow stressed schwas. In most dialects of Russian an unstressed ⟨a⟩ or ⟨o⟩ reduces to a schwa, in dialects of Kashubian a schwa occurs in place of the Old Polish short consonants u, i, y. Many Caucasian languages and some Uralic languages also use phonemic schwa, in the Eastern dialects of Catalan, including the standard variety, based in the dialect spoken in and around Barcelona, an unstressed ⟨a⟩ or ⟨e⟩ is pronounced as a schwa. In the dialects of Catalan spoken in the Balearic Islands, a stressed schwa can occur, stressed schwa can occur in Romanian, as in mătură. In European and some African dialects of Portuguese, the schwa occurs in unstressed syllables that end in ⟨e⟩, such as noite, tarde, pêssego. However, that is rare in Brazilian Portuguese except in areas as Curitiba in Paraná

Close central unrounded vowel
–
The close central unrounded vowel, or high central unrounded vowel, is a type of vowel sound used in some languages. The symbol in the International Phonetic Alphabet that represents this sound is ɨ, both the symbol and the sound are commonly referred to as barred i. In American tradition this symbol denote a different sound, that of the second syllable of roses when distinct from Rosas. Occasionally, this vowel is transcribed ⟨ï⟩ or ⟨ɯ̈⟩, the close central unrounded vowel is the vocalic equivalent of the rare post-palatal approximant. Its vowel backness is central, which means the tongue is positioned halfway between a front vowel and a back vowel and it is unrounded, which means that the lips are not rounded. /ɨ/ is uncommon as a phoneme in Indo-European languages, occurring most commonly as an allophone in some Slavic languages, campbell, Kaufman & Smith-Stark identify the presence of this vowel phoneme as an areal feature of a Mesoamerican Sprachbund. The sound of Polish ⟨y⟩ is often represented as /ɨ/, but actually it is an advanced central unrounded vowel

Close central rounded vowel
–
The close central rounded vowel, or high central rounded vowel, is a type of vowel sound used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ʉ⟩, both the symbol and the sound are commonly referred to as barred u. The close central rounded vowel is the equivalent of the rare labialized post-palatal approximant. The IPA prefers terms close and open for vowels, and the name of the article follows this, however, a large number of linguists, perhaps a majority, prefer the terms high and low. In most languages this rounded vowel is pronounced with protruded lips, however, in a few cases the lips are compressed. There is also a central rounded vowel in some languages. The close central protruded vowel is transcribed in IPA simply as ⟨ʉ⟩. Another possible transcription is ⟨ʉʷ⟩ or ⟨ɨʷ⟩, but this could be misread as a diphthong and its vowel backness is central, which means the tongue is positioned halfway between a front vowel and a back vowel. Its roundedness is protruded, which means that the corners of the lips are drawn together, as there is no official diacritic for compression in the IPA, the centering diacritic is used with the front rounded vowel, which is normally compressed. Another possibility is ⟨ɏ⟩, a centralized by analogy with the close central vowels. Other possible transcriptions are ⟨ɨ͡β̞⟩ and ⟨ɨᵝ⟩ and its vowel backness is central, which means the tongue is positioned halfway between a front vowel and a back vowel. Its roundedness is compressed, which means that the margins of the lips are tense and this vowel is typically transcribed with ⟨ʉ⟩. It occurs in some dialects of Swedish, but see also close front compressed vowel, the close back vowels of Norwegian and Swedish are also compressed. Medumba has a central vowel where the corners of the mouth are not drawn together. Close back compressed vowel Close front protruded vowel

Close back unrounded vowel
–
The close back unrounded vowel, or high back unrounded vowel, is a type of vowel sound used in some spoken languages. Acoustically it is a close back-central unrounded vowel, the symbol in the International Phonetic Alphabet that represents this sound is ⟨ɯ⟩. Typographically a turned letter m, given its relation to the represented by the letter u it can be considered a u with an extra bowl. It is not to be confused with ⟨uɪ⟩, a sequence of the symbols ⟨u⟩ and ⟨ɪ⟩, the IPA prefers terms close and open for vowels, hence the name of this article. However, a number of linguists, perhaps a majority, prefer the terms high. Its vowel backness is back, which means the tongue is positioned as far back as possible in the mouth without creating a constriction that would be classified as a consonant, note that unrounded back vowels tend to be centralized, which means that often they are in fact near-back. It is unrounded, which means that the lips are not rounded, the symbol ⟨ɯ⟩ is sometimes used for Japanese /u/, but that sound is rounded, albeit with labial compression rather than protrusion. It is more accurately described as a close back vowel
12.
Near-close vowel
–
A near-close vowel or a near-high vowel is any in a class of vowel sound used in some spoken languages. The defining characteristic of a vowel is that the tongue is positioned similarly to a close vowel. Near-close vowels are sometimes described as lax variants of the fully close vowels, though, depending on the language. It is rare for languages to contrast a near-close vowel with a close vowel and this contrast is not present in Conservative Danish, which realizes the latter two vowels as, respectively, close-mid and mid. It is even rarer for languages to contrast more than one close/near-close/close-mid triplet, for instance, Sotho has two such triplets, fully front /i–ɪ–e/ and fully back /u–ʊ–o/. In case of language, the near-close vowels /ɪ, ʊ/ tend to be transcribed with the phonetically inaccurate symbols /ɨ, ʉ/
