A stop, plosive, or occlusive is a consonant sound produced by stopping the airflow in the vocal tract. The International Phonetic Alphabet (IPA is a system of phonetic notation based on the Latin alphabet, devised by the International Phonetic In Articulatory phonetics, a consonant is a Speech sound that is articulated with complete or partial closure of the upper Vocal tract, the upper vocal The vocal tract is that cavity in animals and humans where sound that is produced at the sound source ( Larynx in mammals syrinx in birds is filtered The terms plosive and stop are usually used interchangeably, but they are not perfect synonyms. Plosives are stops with a pulmonic egressive airstream mechanism. In human speech egressive sounds are those in which the air stream is created by pushing air out through the mouth or nose In Phonetics, the airstream mechanism is the method by which airflow is created in the vocal tract The term is also used to describe oral (non-nasal) stops. An oral consonant is a Consonant sound in speech that is made by allowing air to escape from the mouth as opposed to the nose Many use the term nasal continuant rather than nasal stop to refer to sounds like [n] and [m]. A continuant is a Sound produced with an incomplete closure of the Vocal tract. One should be aware that this article treats these "nasal continuants" as nasal stops.

Common stops

All languages in the world have stops and most have at least [p], [t], [k], [n], and [m]. Every language in Eurasia, for example, has all five, and often more. However, there are exceptions: Colloquial Samoan lacks the coronals [t] and [n], and the several North American languages, such as the northern Iroquoian languages, lack the labials [p] and [m]. The Sāmoan or Samoan language is the traditional language of Samoa and American Samoa and is an official language &mdash alongside English Coronal consonants are articulated with the flexible front part of the Tongue. The Iroquoian languages are a Native American Language family. Labials are consonants articulated either with both lips ( bilabial articulation or with the lower lip and the upper teeth ( labiodental articulation Some of the Chimakuan, Salishan, and Wakashan languages near Puget Sound lack nasal stops [m] and [n], as does the Rotokas language of Papua New Guinea, and Eyak lacks both labials and nasals, [p], [m], [n]. The Chimakuan language family consists of two languages spoken in northwestern Washington, USA on the Olympic Peninsula. This article is about the Salish/Salishan language For the Tacoma Washington neighborhood see Salishan Tacoma Washington. Wakashan is a family of languages spoken in British Columbia around and on Vancouver Island, and in the northwestern corner of the Olympic Peninsula of Puget Sound (ˈpjuːʤᵻt is an arm of the Pacific Ocean, connected to the rest of the Pacific by the Strait of Juan de Fuca, in the Pacific Northwest A nasal consonant (also called nasal stop or nasal continuant) is produced with a lowered velum in the mouth allowing air to escape freely through the Rotokas is a Language (part of the East Papuan language phylum) spoken by some 4000 people in Bougainville, an island to the east of Papua New Guinea (or ˈpæpjuːə in Tok Pisin: Papua Niugini) officially the Independent State of Papua New Guinea, is a country in Oceania Eyak is an extinct Na-Dené language that was historically spoken in southcentral Alaska, near the mouth of the Copper River. [1] In some African and South American languages, nasal stops occur, but only in the environment of nasal vowels, and so are not distinctive. A nasal vowel is a Vowel that is produced with a lowering of the velum so that air escapes both through Nose as well as the Mouth. Formal Samoan has only one word with velar [k], but it has a nasal velar stop, [ŋ]. The Sāmoan or Samoan language is the traditional language of Samoa and American Samoa and is an official language &mdash alongside English Ni‘ihau Hawaiian, which has /t/ for Standard Hawaiian /k/, can be analysed as having no velars, but in fact its /t/ and /n/ vary in pronunciation, [t]~[k] and [n]~[ŋ]. Niihau ( Hawaiian: Ni‘ihau) is the smallest of the inhabited Hawaiian Islands in the U The Hawaiian language (Hawaiian ‘Ōlelo Hawai‘i) is an Austronesian language that takes its name from Hawai'i, the largest island in the tropical It may be more accurate to say that Hawaiian and colloquial Samoan do not distinguish velar and coronal stops than to say they lack one or the other.

Stop articulation

In the articulation of the stop, three phases can be distinguished:

In many languages, such as Malay and Vietnamese, final stops lack a release burst, or have a nasal release. The Malay language ( ISO 639-1 code MS is an Austronesian language spoken by the Malay people and people of other ethnic groups who reside in the Vietnamese ( tiếng Việt, or less commonly Việt ngữ) formerly known under French colonization as Annamese ( see Annam) In Phonetics, a nasal release is the release of a Plosive consonant into a nasal stop. See Unreleased stop. An unreleased stop or unreleased plosive is a Plosive consonant without an audible release burst

In affricate stops, the release is a fricative. Affricate Consonants begin as stops (most often an alveolar, such as or) but release as a fricative (such as or or occasionally into Fricatives are Consonants produced by forcing air through a narrow channel made by placing two articulators close together

Classification of stops

Voice

Voiced stops are articulated with simultaneous vibration of the vocal cords, voiceless stops without. Voice or voicing is a term used in Phonetics and Phonology to characterize speech sounds, with sounds described as either voiceless The vocal folds, also known commonly as vocal cords, are composed of twin infoldings of Mucous membrane stretched horizontally across the Larynx. Voice or voicing is a term used in Phonetics and Phonology to characterize speech sounds, with sounds described as either voiceless Plosives are commonly voiceless, whereas nasal stops are only rarely so.

Aspiration

In aspirated stops, the voice onset (the time when the vocal cords begin to vibrate) comes perceivably later than the release of the stop. Description Voiceless consonants are produced with the Vocal cords open and voiced consonants are produced when the vocal folds are fractionally closed The vocal folds, also known commonly as vocal cords, are composed of twin infoldings of Mucous membrane stretched horizontally across the Larynx. The duration between the release of the stop and the voice onset is called voice onset time (VOT). Tenuis stops have a voice onset time close to zero, meaning that voicing begins when the stop is released. See also Grassmann's law Spiritus asper Spiritus lenis Voiced stops have a negative voice onset time, meaning the voicing begins before the stop is released. A stop is called "fully voiced" if it is voiced during the entire occlusion. In English, however, initial voiced plosives like [b] or [d] are only partially voiced, meaning that voicing picks up sometime during the occlusion. Aspirated stops have a voice onset time greater than zero, so that there is a period of voiceless airflow (a phonetic [h]) before the onset of the vowel. The voiceless glottal transition, commonly called a " fricative " is a type of sound used in some spoken Languages which often behaves like a

In most dialects of English, the final g in the word bag is likely to be fully voiced, while the initial b will be only partially voiced. Initial voiceless plosives, like the p in pie, are aspirated, with a palpable puff of air upon release, while a plosive after an s, as in spy, is tenuous. Speaking near a candle flame, one will notice that the flame will flicker more when par, tar, car is articulated compared with spar, star, scar.

Length

In a geminate or long stop, the occlusion lasts longer than in normal stops. In Phonetics, gemination happens when a spoken Consonant is pronounced for an audibly longer period of time than a short Consonant. In languages where stops are only distinguished by length (e. g. Arabic, Ilwana, Icelandic), the long stops may last up to three times as long as the short stops. Italian is well known for its geminate stop, as the double t in the name Vittoria takes just as long to say as the ct does in English Victoria. Italian ( or lingua italiana) is a Romance language spoken by about 63 million people as a First language, primarily in Italy. Japanese also prominently features the geminate consonant, such as in the minimal pair 来た (kita), meaning came, and 切った (kitta) meaning cut (past). is a language spoken by over 130 million people in Japan and in Japanese emigrant communities

Note that there are many languages where the features voice, aspiration, and length reinforce each other, and in such cases it may be hard to tell which of these features predominates. In such cases the terms fortis is sometimes used for aspiration or gemination, while lenis is used for single, tenuous or voiced stops. Fortis ( Latin "strong" and lenis ("weak" are linguistic terms Beware, however, that the terms fortis and lenis are poorly defined, and their meanings vary from source to source.

Nasalization

Further information: Nasalization

Nasal stops are differentiated from oral stops only by a lowered velum that allows the air to escape through the nose during the occlusion. In Phonetics, nasalization is the production of a sound while the velum is lowered so that some air escapes through the nose during the production of the sound by A nasal consonant (also called nasal stop or nasal continuant) is produced with a lowered velum in the mouth allowing air to escape freely through the The soft palate (or velum, or muscular palate) is the soft tissue constituting the back of the roof of the Mouth.

Nasal stops are acoustically sonorants, as they have a non-turbulent airflow and are nearly always voiced, but they are articulatorily obstruents, as there is complete blockage of the oral cavity. In Phonetics and Phonology, a sonorant is a Speech sound that is produced without turbulent airflow in the Vocal tract. In Phonetics, articulation may be divided into two large classes obstruents and Sonorants An obstruent is a Consonant sound formed by

A prenasalized stop starts out with a lowered velum that raises during the occlusion. Prenasalized stops or consonants are phonetic sequences of nasal plus plosive that behave phonologically like single consonants The closest examples in English are consonant clusters such as the [nd] in candy, but many languages have prenasalized stops that function phonologically as single consonants. Swahili is well known for having words whose spellings begin with mp or nd, like mtu, though truer prenasalized sounds like [mp] or [nd] do occur word-initially in other bantu languages. Swahili (called Kiswahili in the language itself is the First language of the Swahili people (Waswahili who inhabit several large stretches

A postnasalized stop begins with a raised velum that lowers during the occlusion. In Phonetics, a nasal release is the release of a Plosive consonant into a nasal stop. This causes an audible nasal release, as in English sudden. Russian and other Slavic languages have words that begin with [dn], which can be seen in the name of the Dnieper River. Russian ( transliteration:,) is the most geographically widespread language of Eurasia, the most widely spoken of the Slavic languages For the rocket see Dnepr rocket. For other uses see Dnieper (disambiguation.

Note that the terms prenasalization and postnasalization are normally only used in languages where these sounds are phonemic, that is, not analyzed into sequences of plosive plus nasal stop.

Airstream mechanism

Stops may be made with more than one airstream mechanism. In Phonetics, the airstream mechanism is the method by which airflow is created in the vocal tract The normal mechanism is pulmonic egressive, that is, with air flowing outward from the lungs. In human speech egressive sounds are those in which the air stream is created by pushing air out through the mouth or nose All languages have pulmonic stops. Some languages have stops made with other mechanisms as well: ejective stops (glottalic egressive), implosive stops (glottalic ingressive), or click consonants (velaric ingressive). In Phonetics, ejective consonants are Voiceless Consonants that are pronounced with simultaneous closure of the Glottis. In human speech egressive sounds are those in which the air stream is created by pushing air out through the mouth or nose Implosive consonants are stops (rarely Affricates with a mixed Glottalic ingressive and Pulmonic egressive Airstream mechanism. In human speech ingressive sounds are those in which the airstream is inward through the mouth or nose Clicks are speech sounds such as English tsk! tsk! used to express disapproval or the tchick! used to spur on a horse In human speech ingressive sounds are those in which the airstream is inward through the mouth or nose

Tenseness

Further information: Tenseness

A fortis stop (in the narrow sense) is produced with more muscular tension than a lenis stop (in the narrow sense). In Phonology, tenseness is a particular Vowel or Consonant quality that is phonemically contrastive in many languages including English Fortis ( Latin "strong" and lenis ("weak" are linguistic terms However, this is difficult to measure, and there is usually debate over the actual mechanism of alleged fortis or lenis consonants.

There are a series of stops in Korean, sometimes written with the IPA symbol for ejectives, which are produced using "stiff voice", meaning there is increased contraction of the glottis than for normal production of voiceless stops. This article is mainly about the spoken Korean language See Hangul for details on the native Korean writing system The term stiff voice describes the pronunciation of consonants with a glottal opening narrower and the vocal cords stiffer than what occurs in Modal voice. The indirect evidence for stiff voice is in the following vowels, which have a higher fundamental frequency than those following other stops. The higher frequency is explained as a result of the glottis being tense. Other such phonation types include breathy voice, or murmur; slack voice; and creaky voice. Phonation has slightly different meanings depending on the subfield of Phonetics. Breathy voice (also called murmured voice, soughing, or susurration) is a Phonation in which the Vocal cords vibrate as they do in The term slack voice (or lax voice) describes the pronunciation of consonants with a glottal opening slightly wider than that occurring in Modal voice. Vocal fry registerIn Linguistics, creaky voice (sometimes called laryngealisation, pulse phonation or vocal fry or glottal fry)
