Modern Greek Phonology
This article deals with the phonology and phonetics of Standard Modern Greek. For phonological characteristics of other varieties, see varieties of Modern Greek, and for Cypriot, specifically, see . Consonants Greek linguists do not agree on which consonants to count as phonemes in their own right, and which to count as conditional allophones. The table below is adapted from , who considers the palatals and both affricates, and , to be allophonic. The alveolar nasal is assimilated to following obstruents; it can be labiodental (e.g. 'doubt'), dental (e.g. 'flower'), retracted alveolar (e.g. 'pliers'), alveolo-palatal (e.g. 'to annoy'), or velar (e.g. 'stress'). Voiceless stops are unaspirated and with a very short voice onset time. They may be lightly voiced in rapid speech, especially when intervocalic. 's exact place of articulation ranges from alveolar to denti-alveolar, to dental. It may be fricated in rapid speech, and very rarely, in function words ...

Pi (letter)
Pi (uppercase Π, lowercase π and ϖ; el, πι ) is the sixteenth letter of the Greek alphabet, representing the voiceless bilabial plosive . In the system of Greek numerals it has a value of 80. It was derived from the Phoenician letter Pe (). Letters that arose from pi include Latin P, Cyrillic Pe (П, п), Coptic pi (Ⲡ, ⲡ), and Gothic pairthra (𐍀). Uppercase Pi The uppercase letter Π is used as a symbol for: * In textual criticism, '' Codex Petropolitanus'', a 9th-century uncial codex of the Gospels, now located in St. Petersburg, Russia. * In legal shorthand, it represents a plaintiff. In science and engineering: * The product operator in mathematics, indicated with capital pi notation (in analogy to the use of the capital Sigma as summation symbol). * The osmotic pressure in chemistry. * The viscous stress tensor in continuum mechanics and fluid dynamics. Lowercase Pi The lowercase letter π is used as a symbol for: * The mathematical real transcen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Denti-alveolar
In linguistics, a denti-alveolar consonant or dento-alveolar consonant is a consonant that is articulated with a flat tongue against the alveolar ridge and the upper teeth, such as and in languages such as French, Italian and Spanish. That is, a denti-alveolar consonant is (pre)alveolar and laminal rather than purely dental. Although denti-alveolar consonants are often labeled as " dental" because only the forward contact with the teeth is visible, the point of contact of the tongue that is farthest back is most relevant, as it defines the maximum acoustic space of resonance and gives a characteristic sound to a consonant. In French, the contact that is the farthest back is alveolar or sometimes slightly pre-alveolar. In Spanish, and are laminal denti-alveolar, and and are alveolar but assimilate to a following or . Similarly, in Italian, , , , are denti-alveolar, and and are alveolar. The dental click Dental (or more precisely denti-alveolar) clicks are a fami ...

Place Of Articulation
In articulatory phonetics, the place of articulation (also point of articulation) of a consonant is a location along the vocal tract where its production occurs. It is a point where a constriction is made between an active and a passive articulator. Active articulators are organs capable of voluntary movement which create the constriction, while passive articulators are so called because they are normally fixed and are the parts with which an active articulator makes contact. Along with the manner of articulation and phonation, the place of articulation gives the consonant its distinctive sound. Since vowels are produced with an open vocal tract, the point where their production occurs cannot be easily determined. Therefore, they are not described in terms of a place of articulation but by the relative positions in vowel space. This is mostly dependent on their formant frequencies and less on the specific tongue position and lip rounding. The terminology used in describing place ...

Intervocalic Consonant
In phonetics and phonology, an intervocalic consonant is a consonant that occurs between two vowels. Intervocalic consonants are often associated with lenition, a phonetic process that causes consonants to weaken and eventually disappear entirely. An example of such a change in English is ''intervocalic alveolar flapping'', a process (especially in North American English and Australian English) that, impressionistically speaking, turns ''t'' into ''d'', causing (e.g.) ''metal'' and ''batter'' to sound like ''medal'' and ''badder'', respectively. (More precisely, both /t/ and /d/ are pronounced with the alveolar tap Alveolus (; pl. alveoli, adj. alveolar) is a general anatomical term for a concave cavity or pit. Uses in anatomy and zoology * Pulmonary alveolus, an air sac in the lungs ** Alveolar cell or pneumocyte ** Alveolar duct ** Alveolar macrophage * M ... .) In North American English the weakening is variable across word boundaries, so that the /t/ of "see you tomorrow" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Voice Onset Time
In phonetics, voice onset time (VOT) is a feature of the production of stop consonants. It is defined as the length of time that passes between the release of a stop consonant and the onset of voicing, the vibration of the vocal folds, or, according to other authors, periodicity. Some authors allow negative values to mark voicing that begins during the period of articulatory closure for the consonant and continues in the release, for those unaspirated voiced stops in which there is no voicing present at the instant of articulatory closure. History The concept of voice onset time can be traced back as far as the 19th century, when Adjarian (1899: 119) [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aspirated Consonant
In phonetics, aspiration is the strong burst of breath that accompanies either the release or, in the case of preaspiration, the closure of some obstruents. In English, aspirated consonants are allophones in complementary distribution with their unaspirated counterparts, but in some other languages, notably most South Asian languages (including Indian) and East Asian languages, the difference is contrastive. In dialects with aspiration, to feel or see the difference between aspirated and unaspirated sounds, one can put a hand or a lit candle in front of one's mouth, and say ''spin'' and then ''pin'' . One should either feel a puff of air or see a flicker of the candle flame with ''pin'' that one does not get with ''spin''. Transcription In the International Phonetic Alphabet (IPA), aspirated consonants are written using the symbols for voiceless consonants followed by the aspiration modifier letter , a superscript form of the symbol for the voiceless glottal fricative .

Alveolo-palatal
In phonetics, alveolo-palatal (or alveopalatal) consonants, sometimes synonymous with pre-palatal consonants, are intermediate in articulation between the coronal and dorsal consonants, or which have simultaneous alveolar and palatal articulation. In the official IPA chart, alveolo-palatals would appear between the retroflex and palatal consonants but for "lack of space".John Esling, 2010, "Phonetic Notation". In Hardcastle, Laver, & Gibbon, eds, ''The Handbook of Phonetic Sciences'', p 693 Ladefoged and Maddieson characterize the alveolo-palatals as palatalized postalveolars ( palato-alveolars), articulated with the blade of the tongue behind the alveolar ridge and the body of the tongue raised toward the palate, whereas Esling describes them as advanced palatals (pre-palatals), the furthest front of the dorsal consonants, articulated with the body of the tongue approaching the alveolar ridge. These descriptions are essentially equivalent, since the contact includes both t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Relative Articulation
In phonetics and phonology, relative articulation is description of the manner and place of articulation of a speech sound relative to some reference point. Typically, the comparison is made with a default, unmarked articulation of the same phoneme in a neutral sound environment. For example, the English velar consonant is ''fronted'' before the vowel (as in ''keep'') compared to articulation of before other vowels (as in ''cool''). This fronting is called palatalization. The relative position of a sound may be described as ''advanced'' (''fronted''), ''retracted'' (''backed''), ''raised'', ''lowered'', ''centralized'', or ''mid-centralized''. The latter two terms are only used with vowels, and are marked in the International Phonetic Alphabet with diacritics over the vowel letter. The others are used with both consonants and vowels, and are marked with iconic diacritics under the letter. Another dimension of relative articulation that has IPA diacritics is the degree of ro ...

Obstruent
An obstruent () is a speech sound such as , , or that is formed by ''obstructing'' airflow. Obstruents contrast with sonorants, which have no such obstruction and so resonate. All obstruents are consonants, but sonorants include vowels as well as consonants. Subclasses Obstruents are subdivided into plosives (oral stops), such as , with complete occlusion of the vocal tract, often followed by a release burst; fricatives, such as , with limited closure, not stopping airflow but making it turbulent; and affricates, which begin with complete occlusion but then release into a fricative-like release, such as .Zsiga, Elizabeth. ''The Sounds of Language: An Introduction to Phonetics and Phonology''. Wiley-Blackwell, 2013. Voicing Obstruents are often prototypically voiceless, but voiced obstruents are common. This contrasts with sonorants, which are prototypically voiced and only rarely voiceless. See also *List of phonetics topics A * Acoustic phonetics * Active articulato ...

Homorganic Consonants
In phonetics, a homorganic consonant (from ''homo-'' "same" and ''organ'' "(speech) organ") is a consonant sound that is articulated in the same place of articulation as another. For example, , and are homorganic consonants of one another since they share the bilabial place of articulation. Consonants that are not articulated in the same place are called heterorganic. Articulatory position Descriptive phonetic classification relies on the relationships between a number of technical terms that describe the way sounds are made; and one of the relevant elements involves that place at which a specific sound is formed and voiced. In articulatory phonetics, the specific "place of articulation" or "point of articulation" of a consonant is that point of contact where an obstruction occurs in the vocal tract between an active (moving) articulator (typically some part of the tongue) and a passive (stationary) articulator (typically some part of the roof of the mouth).

Lateral Consonant
A lateral is a consonant in which the airstream proceeds along one or both of the sides of the tongue, but it is blocked by the tongue from going through the middle of the mouth. An example of a lateral consonant is the English ''L'', as in ''Larry''. Lateral consonants contrast with central consonants, in which the airstream flows through the center of the mouth. For the most common laterals, the tip of the tongue makes contact with the upper teeth (see dental consonant) or the upper gum (see alveolar consonant), but there are many other possible places for laterals to be made. The most common laterals are approximant Approximants are speech sounds that involve the articulators approaching each other but not narrowly enough nor with enough articulatory precision to create turbulent airflow. Therefore, approximants fall between fricatives, which do produce a ...s and belong to the class of liquid consonant, liquids, but lateral fricative consonant, fricatives and affricate co ...
