Pulmonic
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 m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ingressive Sound
In phonetics, ingressive sounds are sounds by which the airstream flows inward through the mouth or nose. The three types of ingressive sounds are lingual ingressive or velaric ingressive (from the tongue and the velum), glottalic ingressive (from the glottis), and pulmonic ingressive (from the lungs). The opposite of an ingressive sound is an egressive sound, by which the air stream is created by pushing air out through the mouth or nose. The majority of sounds in most languages, such as /b/, are both pulmonic and egressive. Lingual ingressive Lingual ingressive, or velaric ingressive, describes an airstream mechanism in which a sound is produced by closing the vocal tract at two places of articulation in the mouth. This rarefies the air in the enclosed space by lowering the tongue and then releasing both closures. Such sounds are called " clicks". Glottalic ingressive Glottal ingressive is the term generally applied to the implosive consonants, which actually use a mixed ...

Click Consonant
Click consonants, or clicks, are speech sounds that occur as consonants in many languages of Southern Africa and in three languages of East Africa. Examples familiar to English-speakers are the '' tut-tut'' (British spelling) or '' tsk! tsk!'' (American spelling) used to express disapproval or pity (IPA ), the '' tchick!'' used to spur on a horse (IPA ), and the '' clip-clop!'' sound children make with their tongue to imitate a horse trotting (IPA ). However, these paralinguistic sounds in English are not full click consonants, as they only involve the front of the tongue, without the release of the back of the tongue that is required for clicks to combine with vowels and form syllables. Anatomically, clicks are obstruents articulated with two closures (points of contact) in the mouth, one forward and one at the back. The enclosed pocket of air is rarefied by a sucking action of the tongue (in technical terminology, clicks have a lingual ingressive airstream mechanism). Th ...

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] |
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] |
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.) ''The World Atlas of Language Structures Online.'' Munich: Max Planck Digital Library, chapter 19. Available online at http://wals.info/feature/19. 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.

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.

Egressive Sound
In human speech, egressive sounds are sounds in which the air stream is created by pushing air out through the mouth or nose. The three types of egressive sounds are pulmonic egressive (from the lungs), glottalic egressive (from the glottis), and lingual (velaric) egressive (from the tongue). The opposite of an egressive sound is an ingressive sound, in which the airstream flows inward through the mouth or nose. Pulmonic egressive Pulmonic egressive sounds are those in which the air stream is created by the lung The lungs are the primary Organ (biology), organs of the respiratory system in many animals, including humans. In mammals and most other tetrapods, two lungs are located near the Vertebral column, backbone on either side of the heart. Their ...s, ribs, and diaphragm. The majority of sounds in most languages, such as , are both pulmonic and egressive. Pulmonic egressive sounds are found in all spoken languages. Glottalic egressive Glottalic egressive so ...

Contour (linguistics)
In phonetics, contour describes speech sounds that behave as single segments but make an internal transition from one quality, place, or manner to another. Such sounds may be tones, vowels, or consonants. Many tone languages have '' contour tones'', which move from one level to another. For example, Mandarin Chinese has four lexical tones. The high tone is level, without contour; the falling tone is a contour from high pitch to low; the rising tone a contour from mid pitch to high, and, when spoken in isolation, the low tone takes on a dipping contour, mid to low and then to high pitch. They are transcribed with series of either diacritics or tone letters, which with proper font support fuse into an iconic shape: . In the case of vowels, the terms ''diphthong'' and '' triphthong'' are used instead of 'contour'. They are vowels that glide from one place of articulation to another, as in English ''boy'' and ''bow.'' They are officially transcribed with a non-syllabic sign under ...

Glottalic Consonant
In phonetics, a glottalic consonant is a consonant produced with some important contribution (movement or closure) of the glottis. Glottalic sounds may involve motion of the larynx upward or downward, as the initiator of an egressive or ingressive glottalic airstream mechanism respectively. An egressive glottalic airstream produces ''ejective consonants'', while an ingressive glottalic airstream produces ''implosive consonants''. Ejectives are almost always voiceless stops (plosives) or affricates, while implosives are almost always voiced stops. However, when a sound is said to be '' glottalized'', this is often not what is meant. Rather, glottalization usually means that a normal pulmonic airstream is partially or completely interrupted by closure of the glottis. Sonorants (including vowels) may be glottalized in this fashion. There are three ways this can be represented in the International Phonetic Alphabet: (a) with an apostrophe; (b) with a superscript glottal stop; or ( ...
