Open Vowel

Open vowel

An open vowel is a vowel sound of a type used in most spoken languages. The defining characteristic of an open vowel is that the tongue is positioned as far as possible from the roof of the mouth. Open vowels are sometimes also called low vowels in reference to the low position of the tongue. The open vowels identified the International Phonetic Alphabet are:
- open front unrounded vowel [a]
- open front rounded vowel []
- open back unrounded vowel []
- open back rounded vowel [] In the context of the phonology of any particular language, a low vowel can be any vowel that is more open than a mid vowel. That is, open-mid vowels, near-open vowels, and open vowels can all be considered low vowels. 1 This vowel is not known to occur as a distinct phoneme from in any language. Category:Vowels ja:広母音

Vowel

In phonetics, a vowel is a sound in spoken language that is characterized by an open configuration of the vocal tract where there is no build-up of air pressure above the glottis. This contrasts with consonants, which are characterized by a constriction or closure at one or more points along the vocal tract. The additional requirement is that vowels function as syllabic units: it is this criterion that distinguishes vowels from semivowels (and approximants, which in some languages may be slightly more constricted). In most languages, vowels usually form the nucleus or peak of a syllable, whereas consonants form the onset and coda. However, some languages allow sounds that wouldn't normally be classified as vowels to form the nucleus of a syllable, such as the sound of l in the English word table (the final e is not pronounced), or the sound of r in the Czech word vrba (meaning "willow"). The non-vowel sounds that may function as syllable nuclei are called sonorants. (In some languages, such as Tashlhyt Berber and Oowekyala, non-sonorant consonants can also form the nucleus of a syllable.) The word vowel comes from the Latin word vocalis, meaning "uttering voice" or "speaking".

Articulation

The articulatory features that distinguish different vowels in a language are said to determine the vowel's quality. Daniel Jones developed the cardinal vowel system to describe vowels in terms of the common features height (vertical dimension), backness (horizontal dimension) and roundedness (lip position). These three parameters are indicated in the schematic IPA vowel diagram on right. There are however still more possible features of vowel quality, such the velum position (nasality), type of vocal fold vibration (phonation), and tongue root position.

Height

Height refers to either the vertical position of the tongue relative to the roof of the mouth or the aperture of the jaw. In high vowels, such as i] and u], the tongue is positioned high in the mouth, whereas in low vowels, such as a], the tongue is positioned low in the mouth. Sometimes the terms open and close are used as synonyms for low and high for describing vowels. The International Phonetic Alphabet identifies seven different vowel heights, although no known language distinguishes all seven:
- close vowel (high vowel)
- near-close vowel
- close-mid vowel
- mid vowel
- open-mid vowel
- near-open vowel
- open vowel (low vowel) It may be that some varieties of have five contrasting heights. The Bavarian dialect of Amstetten has thirteen long vowels, reported to be distinguished as four heights (close, close-mid, mid, and near-open) among the front unrounded, front rounded, and back rounded vowels, plus an open central vowel: . Otherwise, the usual limit on the number of vowel heights is four. The parameter of vowel height appears to be the most primary feature of vowels cross-linguistically in that all languages use height constrastively. The other possible parameters, such as backness and roundedness (explained below), are not used in all languages.

Backness

Backness refers to the horizontal tongue position during the articulation of a vowel relative to the back of the mouth. In front vowels, such as , the tongue is positioned forward in the mouth, whereas in back vowels, such as , the tongue is positioned towards the back of the mouth. The International Phonetic Alphabet identifies five different degrees of vowel backness, although no known language distinguishes all five:
- front vowel
- near-front vowel
- central vowel
- near-back vowel
- back vowel The highest number of constrastive degrees of backness is 3.

Roundedness

Roundedness refers to whether the lips are rounded or not. In most languages, roundedness is a reinforcing feature of mid to high back vowels, and not distinctive. Usually the higher a back vowel, the more intense the rounding. However, some languages treat roundedness and backness separately, such as French and German (with front rounded vowels), most Uralic languages ( has a rounding contrast for /o/ and front vowels), Turkic languages (with an unrounded /u/), Vietnamese (with back unrounded vowels), and Korean (with a contrast in both front and back vowels). Nonetheless, even in languages such as German and Vietnamese, there is usually some correlation between rounding and backness: Front rounded vowels tend to be less front than front unrounded vowels, and back unrounded vowels tend to be less back than back rounded vowels. That is, the placement of unrounded vowels to the left of rounded vowels on the IPA vowel chart is reflective of their typical position. Different kinds of labialization are also possible. The /u/, for example, is not rounded like English /u/, where the lips are protruded (or pursed), but neither are the lips spread to the sides as they are for unrounded vowels. Rather, they are compressed in both directions, leaving a slot between the lips for the air to escape. (See Vowel roundedness for illustrations.) Swedish is one of the few languages where this feature is contrastive, have both protruded-lip and compressed-lip high front vowels. In many treatments, both are considered a type of rounding, and are often called endolabial rounding (pursed, where the insides of the lips approach each other) and exolabial rounding (compressed, where the margins of the lips approach each other). However, other phoneticians do not believe that these are subsets of a single phenomenon of rounding, and prefer instead the three independent terms rounded, compressed, and spread (for unrounded).

Nasalization

Nasalization refers to whether some of the air escapes through the nose. In nasal vowels, the velum is lowered, and some air travels through the nasal cavity as well as the mouth. An oral vowel is a vowel in which all air escapes through the mouth. French, Polish and Portuguese contrast nasal and oral vowels.

Phonation

Voicing describes whether the vocal cords are vibrating during the articulation of a vowel. Most languages only have voiced vowels, but several Native American languages, such as Cheyenne and Totonac, contrast voiced and devoiced vowels. Vowels are devoiced in whispered speech. As in Japanese and Quebec French, vowels that are between voiceless consonants are often devoiced. Modal voice, creaky voice, and breathy voice (murmured vowels) are phonation types that are used contrastively in some languages. Often, these co-occur with tone or stress distinctions; in the Mon language, vowels pronounced in the high tone are also produced with creaky voice. In cases like this, it can be unclear whether it is the tone, the voicing type, or the pairing of the two that is being used for phonemic contrast. This combination of phonetic cues (i.e. phonation, tone, stress) is known as register or register complex.

Tongue root retraction

Advanced tongue root (ATR) is a feature common across much of Africa. The contrast between advanced and retracted tongue root resembles the tense/lax contrast acoustically, but they are articulated differently. ATR vowels involve noticeable tension in the vocal tract.

Secondary narrowings in the vocal tract

Pharyngealized vowels occur in some languages; Sedang uses this contrast, as do the Tungusic languages. Pharyngealisation is similar in articulation to retracted tongue root, but is acoustically distinct. A stronger degree of pharyngealisation occur in the Northeast Caucasian languages and the Khoisan languages. These might be called epiglottalized, since the primary constriction is at the tip of the epiglottis. The greatest degree of pharyngealisation is found in the strident vowels of the Khoisan languages, where the larynx is raised, and the pharynx constricted, so that either the epiglottis or the arytenoid cartilages vibrate instead of the vocal chords. Note that the terms pharyngealized, epiglottalized, strident, and sphincteric are sometimes used interchangeably.

Rhotic vowels

Rhotic vowels are the "ar-colored vowels" of English and a few other languages.

Tenseness/checked vowels vs. free vowels

Tenseness is used to describe the opposition of tense vowels as in leap, suit vs. lax vowels as in lip, soot. This opposition has traditionally been thought to be a result of greater muscular tension, though phonetic experiments have repeatedly failed to show this. Unlike the other features of vowel quality, tenseness is only applicable to the few languages that have this opposition (mainly Germanic languages, e.g. English), whereas the vowels of the other languages (e.g. Spanish) cannot be described with respect to tenseness in any meaningful way. In most Germanic languages, lax vowels can only occur in closed syllables. Therefore, they're also known as checked vowels, whereas the tense vowels are called free vowels since they can occur in any kind of syllable.

Acoustics

free vowel The acoustics of vowels are fairly well-understood. The different vowel qualities are realized in acoustic analyses of vowels by the relative values of the formants, acoustic resonances of the vocal tract which show up as dark bands on a spectrogram. The vocal tract acts as a resonant cavity, and the position of the jaw, lips, and tongue affect the parameters of the resonant cavity, resulting in different formant values. The acoustics of vowels can be visualized using spectrograms, which display the acoustic energy at each frequency, and how this changes with time. The first formant, abbreviated "F1", corresponds to vowel openness (vowel height). Open vowels have high F1 frequences while close vowels have low F1 frequencies, as can be seen at right: The and have similar low first formants, whereas has a higher formant. The second formant, F2, corresponds to vowel frontness. Back vowels have low F2 frequencies while front vowels have high F2 frequencies. This is very clear at right, where the front vowel has a much higher F2 frequency than the other two vowels. However, in open vowels the high F1 frequency forces a rise in the F2 frequency as well, so a better measure of frontness is the difference between the first and second formants. For this reason, vowels are usually plotted as F1 vs. F2 – F1. This is the case for the vowel chart at the top of this page. (This dimension is usually called 'backness' rather than 'frontness', but the term 'backness' can be counterintuitive when discussing formants.) R-colored vowels are characterized by lowered F3 values. Rounding is generally realized by a complex relationship between F2 and F3 that tends to reinforce vowel backness. One effect of this is that back vowels are most commonly rounded while front vowels are most commonly unrounded; another is that rounded vowels tend to plot to the right of unrounded vowels in vowel charts. That is, there is a reason for plotting vowel pairs the way they are.

Prosody and intonation

The features of vowel prosody are often described independently from vowel quality. In non-linear phonetics, they are located on parallel layers. The features of vowel prosody are usually considered not to apply to the vowel itself, but to the syllable, as some languages do not contrast vowel length separately from syllable length. Intonation encompasses the changes in pitch, intensity, and speed of an utterance over time. In tonal languages, in most cases the tone of a syllable is carried by the vowel, meaning that the relative pitch or the pitch contour that marks the tone is superimposed on the vowel. If a syllable has a high tone, for example, the pitch of the vowel will be high. If the syllable has a falling tone, then the pitch of the vowel will fall from high to low over the course of uttering the vowel. Length or quantity refers to the abstracted duration of the vowel. In some analyses this feature is described as a feature of the vowel quality, not of the prosody. Japanese, Finnish, Hungarian, Arabic and Latin have a two-way phonemic contrast between short and long vowels. The Mixe language has a three-way contrast among short, half-long, and long vowels, and this has been reported from a few other languages, in not all of which is the distinction phonemic. Long vowels are written in the IPA with a triangular colon, which has two equilateral triangles pointing at each other in place of dots (). The IPA symbol for half-long vowels is the top half of this (). Longer vowels are sometimes claimed, but these are always divided between two syllables. It should be noted that the length of the vowel is a grammatical abstraction, and there may be more phonologically distinctive lengths. For example, in Finnish, there are five different physical lengths, because stress is marked with length on both grammatically long and short vowels. However, Finnish stress is not lexical and is always on the first two moras, thus this variation serves to separate words from each other. In non-tonal languages, like English, intonation encompasses lexical stress. A stressed syllable will typically be pronounced with a higher pitch, intensity, and length than unstressed syllables. For example in the word intensity, the vowel represented by the letter 'e' is stressed, so it is longer and pronounced with a higher pitch and intensity than the other vowels.

Monophthongs, diphthongs, triphthongs

A vowel sound whose quality doesn't change over the duration of the vowel is called a monophthong. Monophthongs are sometimes called "pure" or "stable" vowels. A vowel sound that glides from one quality to another is called a diphthong, and a vowel sound that glides between three qualities is a triphthong. All languages have monophthongs and many languages have diphthongs, but triphthongs or vowel sounds with even more target qualities are relatively rare cross-linguistically. English has all three types: the vowel sound in hit is a monophthong , the vowel sound in boy is in most dialects a diphthong , and the vowel sounds of way , flower (BrE AmE ) form a triphthong (dissylabic in the latter cases), although the particular qualities vary by dialect. The longest sensible word with most consecutive vowels is Finnish riiuuyöaieuutinen (courting night intention news [certainly yellow press stuff!]), syllabicated rii-uu-yö-ai-e-uu-ti-nen. In phonology, diphthongs and triphthongs are distinguished from sequences of monophthongs by whether or not the vowel sound may be analyzed into different phonemes or not. For example, the vowel sounds in a two-syllable pronunciation of the word flower (BrE AmE ) phonetically form a dissyllabic triphthong, but are phonologically a sequence of a diphthong (represented by the letters ) and a monophthong (represented by the letters ). Some linguists use the terms diphthong and triphthong only in this phonemic sense.

Vowels in languages

The semantic significance of vowels varies widely depending on the language. In some languages, particularly Semitic languages, vowels mostly serve to denote inflections. This is similar to English man vs. men. In fact, the alphabets used to write the Semitic languages, such as the Hebrew alphabet and the Arabic alphabet, do not ordinarily mark all the vowels. These alphabets are called abjads. Although it is possible to construct simple English sentences that can be understood without written vowels (cn y rd ths?), extended passages of English lacking written vowels are difficult if not impossible to completely understand (consider dd, which could be any of add, aided, dad, dada, dead, deed, did, died, dodo, dud, dude, eddie, iodide, or odd). In most languages, vowels are an unchangeable part of the words, as in English man vs. moon which are not different inflectional forms of the same word, but different words. Vowels are especially important to the structures of words in languages that have very few consonants (like Polynesian languages such as Maori and Hawaiian), and in languages whose inventory of vowels is larger than its inventory of consonants.

Vowel systems

Most languages have 3–7 vowels, the following 5-vowel system being the most common: This particular configuration is common because it makes the most efficient use of the vowel space, so slight variations in a vowel are not easily confused for a different sound. Spanish and Modern Greek, for example, have this vowel system; Latin had a similar system that also distinguished between long and short vowels, although that distinction wasn't made in written Latin; it is for this reason that the Latin alphabet has five vowel letters. All languages have at least two vowels; the Tshwizhyi and Abzhui dialects of Abkhaz contrasts only and , with significant allophony. (There have been proposals to posit only one vowel in some Abkhaz dialects; however, most linguists who are familiar with Abkhaz do not accept this theory.) Three-vowel systems have been noted in a number of languages. These include:
- (Arabic, Inuktitut, Quechua),
- (Pirahã),
- (Wichita). A few languages, such as Navajo, have four-vowel systems that lack /u/ but there is no known natural language that lacks some form of a. At the other end of the spectrum, languages with more than twelve vowels are relatively uncommon, although some widely-spoken languages have large vowel inventories, particularly Germanic languages. For example, English has 14–20 vowels (including diphthongs) depending on dialect, and Swedish has 17 distinct vowel qualities in the height-backness-roundedness spectrum, although these also involve a length contrast, and the long vowels have diphthongized allophones. French has 16 vowel qualities, including nasals, and the previously-mentioned Sedang has 24 distinct monophthongs, which it achieves by contrasting phonation on seven vowel qualities. uses phonation and nasalization with five vowel qualities to achieve approximately 40 vowels, most of which may occur both long and short.

Written vowels

The name "vowel" is often used for the symbols used for representing vowel sounds in a language's writing system, particularly if the language uses an alphabet. In the Latin alphabet, the vowel letters are usually A, E, I, O, U, and in some languages Y, as in English and W, as in Welsh. There is necessarily not a direct one-to-one correspondence between the vowel sounds of a language and the vowel letters. Many languages that use a form of the Latin alphabet have more vowel sounds than can be represented by the standard set of five vowel letters. In the case of English, the five primary vowel letters can represent both long and short vowel sounds (some of the long vowel sounds in English are actually diphthongs). Furthermore, in English some vowel sounds are represented by combinations of vowel letters, such as the ea in beat or by a vowel letter and an approximant letter, as the ow in how, or the er in her. Other languages cope with the limitation in the number of Latin vowel letters in similar ways. Many languages, like English, make extensive use of combinations of vowel letters to represent various sounds. Other languages add diacritical marks to vowels, such as accents or umlauts, to represent the variety of possible vowel sounds. Some languages have also constructed additional vowel letters by modifying the standard Latin vowels in other ways, such as æ or ø that are found in some of the Scandinavian languages. The International Phonetic Alphabet has a set of 28 symbols to represent the range of basic vowel qualities, and a further set of diacritics to denote variations from the basic vowel.

Language

A language is a system of symbols, generally known as lexemes and the rules by which they are manipulated. The word language is also used to refer to the whole phenomenon of language, i.e., the common properties of languages. Though language is commonly used for communication, it is not synonymous with it. Human language is a natural phenomenon, and language learning is instinctive in childhood. In their natural form, human languages use patterns of sound or gesture for the symbols in order to communicate with others through the senses. Though there are thousands of human languages, they all share a number of properties from which there are no known deviations. Humans have also invented (or arguably in some cases discovered) many other languages, including constructed human languages such as Esperanto or Klingon, programming languages such as Python or Ruby, and various mathematical formalisms. These languages are not restricted to the properties shared by natural human languages.

Properties of language

Languages are not just sets of symbols. They also contain a grammar, or system of rules, used to manipulate the symbols. While a set of symbols may be used for expression or communication, it is primitive and relatively unexpressive, because there are no clear or regular relationships between the symbols. Because a language also has a grammar, it can manipulate its symbols to express clear and regular relationships between them. For example, imagine going on a walk with a person who only knew individual symbols, or words. If you saw a dog, he might say, "Dog scare" or "Scare Dog". Although any English speaker would have some notion of what he was talking about, the relationship between the words is unclear. Is he scared of dogs? Or just that dog? Or does he want to scare the dog off? Does he think the dog is scared? But if you respond, "I’m not scared of dogs," the relationship between dog and scare is quite apparent and hence the meaning of the utterance. Another important property of language is the arbitrariness of the symbols. Any symbol can be mapped onto any concept (or even onto one of the rules of the grammar). For instance, there is nothing about the Spanish word nada itself that forces Spanish speakers to use it to mean nothing. That is the meaning all Spanish speakers have memorized for that sound pattern. But for Croatian speakers nada means hope. However, it must be understood that just because in principle the symbols are arbitrary does not mean that a language cannot have symbols that are iconic of what they stand for. Words such as meow sound similar to what they represent, but they could be replaced with words such as jarn, and as long as everyone memorized the new word, the same concepts could be expressed with it.

Human languages

Human languages are usually referred to as natural languages, and the science studying them is linguistics. Making a principled distinction between one language and another is usually impossible. For example, the boundaries between named language groups are in effect arbitrary due to blending between populations (the dialect continuum). For instance, there are dialects of German very similar to Dutch which are not mutually intelligible with other dialects of (what Germans call) German. Some like to make parallels with biology, where it is not always possible to make a well-defined distinction between one species and the next. In either case, the ultimate difficulty may stem from the interactions between languages and populations. (See Dialect or August Schleicher for a longer discussion.) The concepts of Ausbausprache, Abstandsprache, and Dachsprache are used to make finer distinctions about the degrees of difference between languages or dialects.

Origins of human language

Scientists do not yet agree on when language was first used by humans (or their ancestors). Estimates range from about two million (2,000,000) years ago, during the time of Homo habilis, to as recently as forty thousand (40,000) years ago, during the time of Cro-Magnon man. The nature of speech means that there is almost no data on which to base conclusions on the subject.

Language taxonomy

The classification of natural languages can be performed on the basis of different underlying principles (different closeness notions, respecting different properties and relations between languages); important directions of present classifications are:
- paying attention to the historical evolution of languages results in a genetic classification of languages—which is based on genetic relatedness of languages,
- paying attention to the internal structure of languages (grammar) results in a typological classification of languages—which is based on similarity of one or more components of the language’s grammar across languages,
- and respecting geographical closeness and contacts between language-speaking communities results in areal groupings of languages. The different classifications do not match each other and are not expected to, but the correlation between them is an important point for many linguistic research works. (There is a parallel to the classification of species in biological phylogenetics here: consider monophyletic vs. polyphyletic groups of species.) The task of genetic classification belongs to the field of historical-comparative linguistics, of typological—to linguistic typology. See also: Taxonomy, Taxonomic classification—for the general idea of classification and taxonomies.

Genetic classification

The world’s languages have been grouped into families of languages that are believed to have common ancestors. Some of the major families are the Indo-European languages, the Afro-Asiatic languages, the Austronesian languages, and the Sino-Tibetan languages. The shared features of languages from one family can be due to shared ancestry. (Compare with homology in biology.)

Typological classification

An example of a typological classification is the classification of languages on the basis of the basic order of the verb, the subject and the object in a sentence into several types: SVO, SOV, VSO, and so on, languages. (, for instance, belongs to the SVO language type.) The shared features of languages of one type (= from one typological class) may have arisen completely independently. (Compare with analogy in biology.) Their cooccurence might be due to the universal laws governing the structure of natural languages—language universals.

Areal classification

The following language groupings can serve as some linguistically significant examples of areal linguistic units, or sprachbunds: Balkan linguistic union, or the bigger group of European languages; Caucasian languages. Although the members of each group are not closely genetically related, there is a reason for them to share similar features, namely: their speakers have been in contact for a long time within a common community and the languages converged in the course of the history. These are called areal features. NB. One should be careful about the underlying classification principle for groups of languages which have apparently a geographical name: besides areal linguistic units, the taxa of the genetic classification (language families) are often given names which themselves or parts of which refer to geographical areas.
Constructed languages
One prominent artificial language, called Esperanto, was created by L. L. Zamenhof. It is a compilation of various elements of different languages, and it is intended to be an easy-to-learn language. Another prominent artificial language, called Ido, is intended to be reformed Esperanto. Other constructed languages strive to be more logical than natural languages; a prominent example of this is Lojban. Other writers, such as J. R. R. Tolkien, have created fantasy languages, for literary, artistic, or personal reasons. One of Tolkien’s languages is called Quenya, which is a form of Elvish. It has its own alphabet, and its phonology and syntax are modelled on Finnish. Linguist Mark Okrand has devised Klingon and Vulcan for Star Trek, which have since been developed into full languages.
The study of language
The oldest surviving written grammar for any language is believed to be the Tolkāppiyam (தொல்காப்பியம்), a book on the grammar of the Tamil language, written around 200 BCE by Tolkāppiyar. Its classification of the alphabet into consonants and vowel was a breakthrough. The historical record of the study of language begins in North India with Pāṇini, the 5th century BCE grammarian who formulated 3,959 rules of Sanskrit morphology, known as the (अष्टाध्यायी). grammar is highly systematized and technical. Inherent in its analytic approach are the concepts of the phoneme, the morpheme, and the root; the phoneme was only recognized by Western linguists some two millennia later. In the Middle East, the Persian linguist Sibawayh made a detailed and professional description of Arabic in 760 CE in his monumental work, Al-kitab fi an-nahw (الكتاب في النحو, The Book on Grammar), bringing many linguistic aspects of language to light. In his book he distinguished phonetics from phonology. Later in the West, the success of science, mathematics, and other formal systems in the 20th century led many to attempt a formalization of the study of language as a "semantic code". This resulted in the academic discipline of linguistics, the founding of which is attributed to Ferdinand de Saussure.
Animal (nonhuman) language
While the term animal languages is widely used, most researchers agree that they are not as complex or expressive as human language; a more accurate term is animal communication. Some researchers argue that there are significant differences separating human language from the communication of other animals, and that the underlying principles are not related. In several widely publicised instances, animals have been trained to mimic certain features of human language. For example, chimpanzees and gorillas have been taught hand signs based on American Sign Language; however, they have never been taught its grammar. There was also a case in 2003 of Kanzi, a captive bonobo chimpanzee allegedly independently creating some words to mean certain concepts. While animal communication has debated levels of semantics, it has not been shown to have syntax in the sense that human languages do. Some researchers argue that a continuum exists among the communication methods of all social animals, pointing to the fundamental requirements of group behaviour and the existence of "mirror cells" in primates. This, however, may not be a scientific question, but is perhaps more one of definition. What exactly is the definition of the word "language"? Most researchers agree that, although human and more primitive languages have analogous features, they are not homologous.
Formal languages
Mathematics and computer science use artificial entities called formal languages (including programming languages and markup languages, but also some that are far more theoretical in nature). These often take the form of character strings, produced by some combination of formal grammar and semantics of arbitrary complexity.

Open front unrounded vowel

The open front unrounded vowel is a type of vowel sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is , and the equivalent X-SAMPA symbol is a. This symbol is very frequently used for an open central unrounded vowel, and this usage is accepted by the International Phonetic Association. Since no language distinguishes front from central open vowels, a separate symbol is not considered necessary. If required, the difference may be specified with the central diacritic, .

Features

- Its vowel height is open, which means the tongue is positioned as far as possible from the roof of the mouth.
- Its vowel backness is front which means the tongue is positioned as far forward as possible in the mouth without creating a constriction that would be classified as a consonant. This subsumes central open vowels because the tongue does not have as much flexibility in positioning as it does for the close vowels; the difference between an open front vowel and an open back vowel is equal to the difference between a close front and a close mid vowel, or a close mid and a close back vowel.
- Its vowel roundedness is unrounded, which means that the lips are not rounded.

Occurs in

Most languages have some form of an unrounded open vowel. For languages that only have a single low vowel, the symbol for this vowel (a) is usually used because it is the only low vowel whose symbol is part of the basic Latin alphabet. However, in all of the following languages except Igbo, the is closer to a central [ä] than to a front [a].

In English

- (AuE and NZE) cut and cart
- In GA this vowel occurs only as the first part of the diphthongs , as in light ; and , as in how . However, in the Great Lakes region, this vowel occurs in words like stock as a result of the Northern Cities Vowel Shift.
- In traditional RP this vowel occurs only in the same diphthongs as it does in GA. However many British English accents (especially in Northern England and Scotland) use it where RP usually uses , in words such as trap and bat. The symbol is now used for the vowel of British English trap and bat in dictionaries of the Oxford University Press.
- In many varieties of Canadian English, it occurs in words like bat as a result of the Canadian Shift.
- This vowel occurs in the Boston accent, for example in star and father .

- near-open front unrounded vowel []
