Plosive
In phonetics, a plosive, also known as an occlusive or simply a stop, is a pulmonic consonant in which the vocal tract is blocked so that all airflow ceases. The occlusion may be made with the tongue tip or blade (, ), tongue body (, ), lips (, ), or glottis (). Plosives contrast with nasals, where the vocal tract is blocked but airflow continues through the nose, as in and , and with fricatives, where partial occlusion impedes but does not block airflow in the vocal tract. Terminology The terms ''stop, occlusive,'' and ''plosive'' are often used interchangeably. Linguists who distinguish them may not agree on the distinction being made. "Stop" refers to the stopping of the airflow, "occlusive" to the articulation which occludes (blocks) the vocal tract, and "plosive" to the plosion (release burst) of the consonant. Some object to the use of "plosive" for inaudibly released stops, which may then instead be called "applosives". The International Phonetic Association and ...

Implosive Consonant
Implosive consonants are a group of stop consonants (and possibly also some affricates) with a mixed glottalic ingressive and pulmonic egressive airstream mechanism. That is, the airstream is controlled by moving the glottis downward in addition to expelling air from the lungs. Therefore, unlike the purely glottalic ejective consonants, implosives can be modified by phonation. Contrastive implosives are found in approximately 13% of the world's languages. In the International Phonetic Alphabet, implosives are indicated by modifying the top of a letter (voiced stop) with a rightward-facing hook: . Articulation During the occlusion of the stop, pulling the glottis downward rarefies the air in the vocal tract. The stop is then released. In languages whose implosives are particularly salient, that may result in air rushing into the mouth before it flows out again with the next vowel. To take in air sharply in that way is to implode a sound. However, probably more typically, there ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ejective Consonant
In phonetics, ejective consonants are usually voiceless consonants that are pronounced with a Airstream mechanism#Glottalic initiation, glottalic egressive airstream. In the phonology of a particular language, ejectives may contrast with Aspirated consonant, aspirated, voiced and tenuis consonants. Some languages have glottalized sonorants with creaky voice that pattern with ejectives phonologically, and other languages have ejectives that pattern with Implosive consonant, implosives, which has led to phonologists positing a phonological class of glottalic consonants, which includes ejectives. Description In producing an ejective, the stylohyoid muscle and digastric muscle contract, causing the hyoid bone and the connected glottis to rise, and the forward articulation (at the velum in the case of ) is held, raising air pressure greatly in the mouth so when the oral articulators separate, there is a dramatic burst of air. The Adam's apple may be seen moving when the sound is prono ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airstream Mechanism
In phonetics, the airstream mechanism is the method by which airflow is created in the vocal tract. Along with phonation and articulation, it is one of three main components of speech production. The airstream mechanism is mandatory for most sound production and constitutes the first part of this process, which is called initiation. The organ generating the airstream is called the ''initiator'' and there are three initiators used phonemically in non-disordered human oral languages: * the diaphragm together with the ribs and lungs ''(pulmonic'' mechanisms), * the glottis ''(glottalic'' mechanisms), and * the tongue ''(lingual'' or ''"velaric"'' mechanisms). There are also methods of making sounds that do not require the glottis. These mechanisms are collectively called alaryngeal speech mechanisms (none of these speech mechanisms are used in non-disordered speech): * the cheeks ''(buccal'' mechanisms, notated in VoQS). See buccal speech. * after a laryngectomy, the esophagus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vietnamese Language
Vietnamese () is an Austroasiatic languages, Austroasiatic language Speech, spoken primarily in Vietnam where it is the official language. It belongs to the Vietic languages, Vietic subgroup of the Austroasiatic language family. Vietnamese is spoken natively by around 86 million people, and as a second language by 11 million people, several times as many as the rest of the Austroasiatic family combined. It is the native language of Vietnamese people, ethnic Vietnamese (Kinh), as well as the second language, second or First language, first language for List of ethnic groups in Vietnam, other ethnicities of Vietnam, and used by Overseas Vietnamese, Vietnamese diaspora in the world. Like many languages in Southeast Asia and East Asia, Vietnamese is highly analytic language, analytic and is tone (linguistics), tonal. It has head-initial directionality, with subject–verb–object order and modifiers following the words they modify. It also uses noun classifier (linguistics), classi ...

Manner Of Articulation
articulatory phonetics, the manner of articulation is the configuration and interaction of the articulators ( speech organs such as the tongue, lips, and palate) when making a speech sound. One parameter of manner is ''stricture,'' that is, how closely the speech organs approach one another. Others include those involved in the r-like sounds ( taps and trills), and the sibilancy of fricatives. The concept of manner is mainly used in the discussion of consonants, although the movement of the articulators will also greatly alter the resonant properties of the vocal tract, thereby changing the formant structure of speech sounds that is crucial for the identification of vowels. For consonants, the place of articulation and the degree of phonation or 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. Often nasality and laterality are inclu ...

Occlusive
In phonetics, an occlusive, sometimes known as a stop, is a consonant sound produced by occluding (i.e. blocking) airflow in the vocal tract, but not necessarily in the nasal tract. The duration of the block is the ''occlusion'' of the consonant. An occlusive may refer to one or more of the following, depending on the author: * Stops, or more precisely, oral stops—also known as plosives—are oral occlusives, where the occlusion of the vocal tract stops all airflow—oral and nasal. :Examples in English are ( voiced) , , and ( voiceless) , , . * Nasals, also known as nasal stops, are nasal occlusives, where occlusion of the vocal tract shifts the airflow to the nasal tract. :Examples in English are , , and . * Affricates such as English , are partial occlusives. Typically ''stops'' and ''affricates'' are contrasted, but affricates are also described as ''stops with fricative release'', contrasting with ''simple stops'' (= plosives). * Implosives, in which the airstream d ...

Phonetics
Phonetics is a branch of linguistics that studies how humans produce and perceive sounds or, in the case of sign languages, the equivalent aspects of sign. Linguists who specialize in studying the physical properties of speech are phoneticians. The field of phonetics is traditionally divided into three sub-disciplines on questions involved such as how humans plan and execute movements to produce speech (articulatory phonetics), how various movements affect the properties of the resulting sound (acoustic phonetics) or how humans convert sound waves to linguistic information (auditory phonetics). Traditionally, the minimal linguistic unit of phonetics is the phone (phonetics), phone—a speech sound in a language which differs from the phonological unit of phoneme; the phoneme is an abstract categorization of phones and it is also defined as the smallest unit that discerns meaning between sounds in any given language. Phonetics deals with two aspects of human speech: production ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Affricate
An affricate is a consonant that begins as a stop and releases as a fricative, generally with the same place of articulation (most often coronal). It is often difficult to decide if a stop and fricative form a single phoneme or a consonant pair. English has two affricate phonemes, and , often spelled ''ch'' and ''j'', respectively. Examples The English sounds spelled "ch" and "j" ( broadly transcribed as and in the IPA), German and Italian ''z'' and Italian ''z'' are typical affricates, and sounds like these are fairly common in the world's languages, as are other affricates with similar sounds, such as those in Polish and Chinese. However, voiced affricates other than are relatively uncommon. For several places of articulation they are not attested at all. Much less common are labiodental affricates, such as in German, Kinyarwanda and Izi, or velar affricates, such as in Tswana (written ''kg'') or in High Alemannic Swiss German dialects.

Pulmonic Consonant
A pulmonic consonant is a consonant produced by air pressure from the lungs, as opposed to ejective, implosive and click consonants. Most languages have only pulmonic consonants. Ian Maddieson, in his survey of 566 languages,Ian Maddieson (2008) "Presence of Uncommon Consonants". In: Martin Haspelmath & Matthew S. Dryer & David Gil & Bernard Comrie (eds.)

Accessed on 18 January 2011 found that only 152 had ejectives, implosives, or clicks (or two or three of these types) – that is, 73% of the world's extant languages have only pulmonic consonants. See glottalic consonants and click consonants for more information on the distribution of nonpulmonic consonants.

Fricatives
A fricative is a consonant produced by forcing air through a narrow channel made by placing two articulators close together. These may be the lower lip against the upper teeth, in the case of ; the back of the tongue against the soft palate in the case of German (the final consonant of '' Bach''); or the side of the tongue against the molars, in the case of Welsh (appearing twice in the name ''Llanelli''). This turbulent airflow is called frication. A particular subset of fricatives are the sibilants. When forming a sibilant, one still is forcing air through a narrow channel, but in addition, the tongue is curled lengthwise to direct the air over the edge of the teeth. English , , , and are examples of sibilants. The usage of two other terms is less standardized: "Spirant" is an older term for fricatives used by some American and European phoneticians and phonologists for non-sibilant fricatives. "Strident" could mean just "sibilant", but some authors include also labiode ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unreleased Stop
A stop consonant with no audible release, also known as an unreleased stop, checked stop or an applosive, is a plosive with no release burst: no audible indication of the end of its occlusion (hold). In the International Phonetic Alphabet, lack of an audible release is denoted with an upper-right corner diacritic () after the consonant letter, as in: , , . Audibly released stops, on the other hand, are not normally indicated. If a final stop is aspirated, the aspiration diacritic is sufficient to indicate the release. Otherwise, the "unaspirated" diacritic of the Extended IPA may be employed for this: ''apt'' . English In most dialects of English, the first stop of a cluster has no audible release, as in ''apt'' , ''doctor'' , or ''logged on'' . Although such sounds are frequently described as "unreleased", the reality is that since the two consonants overlap, the release of the former takes place during the hold of the latter, masking the former's release and making it inaud ...
