In phonology and phonetics, raising is a sound change in which a vowel or consonant becomes higher or raised, meaning that the tongue becomes more elevated or positioned closer to the roof of the mouth than before. The opposite effect is known as lowering. Raising or lowering may be triggered by a nearby sound, when it is a form of assimilation, or it may occur on its own.
In i-mutation, a front vowel is raised before /i/ or /j/, which is assimilation.
In the Attic dialect of Ancient Greek and in Koine Greek, close-mid /eːoː/ were raised to /iːuː/. The change occurred in all cases and was not triggered by a nearby front consonant or vowel. Later, Ancient Greek /ɛː/ was raised to become Koine Greek [eː] and then [iː]. For more information, see Ancient Greek phonology § Vowel raising and fronting
In Czech, the alveolar trill /r/ was raised before /i/ to become the raised alveolar trill /r̝/, spelled ⟨ř⟩ as in ⟨ Dvořák ⟩. That is a form of palatalization, and it also occurred in Polish in which it became a simple sibilant fricative /ʐ/ (spelled ⟨rz⟩ or ⟨ż⟩) around the 16th century. The pronunciation [ r̝ ] in Polish is considered to be nonstandard and is used only by some older speakers.
In phonology, an allophone is one of multiple possible spoken sounds – or phones – used to pronounce a single phoneme in a particular language. For example, in English, the voiceless plosive and the aspirated form are allophones for the phoneme, while these two are considered to be different phonemes in some languages such as Central Thai. Similarly, in Spanish, and are allophones for the phoneme, while these two are considered to be different phonemes in English.
In articulatory phonetics, a consonant is a speech sound that is articulated with complete or partial closure of the vocal tract, except for the h, which is pronounced without any stricture in the vocal tract. Examples are and [b], pronounced with the lips; and [d], pronounced with the front of the tongue; and [g], pronounced with the back of the tongue;, pronounced throughout the vocal tract;, [v], and, pronounced by forcing air through a narrow channel (fricatives); and and, which have air flowing through the nose (nasals). Most consonants are pulmonic, using air pressure from the lungs to generate a sound. Very few natural languages are non-pulmonic, making use of ejectives, implosives, and clicks. Contrasting with consonants are vowels.
The International Phonetic Alphabet (IPA) is an alphabetic system of phonetic notation based primarily on the Latin script. It was devised by the International Phonetic Association in the late 19th century as a standardized representation of speech sounds in written form. The IPA is used by lexicographers, foreign language students and teachers, linguists, speech–language pathologists, singers, actors, constructed language creators, and translators.
Liquids are a class of consonants that consists of rhotics and voiced lateral approximants, sometimes described as "r-like sounds" and "l-like sounds". The word liquid seems to be a calque of the Ancient Greek word ὑγρός, initially used by grammarian Dionysius Thrax to describe Greek sonorants.
In phonetics, rhotic consonants, or "R-like" sounds, are liquid consonants that are traditionally represented orthographically by symbols derived from the Greek letter rho, including ⟨R⟩, ⟨r⟩ in the Latin script and ⟨Р⟩, ⟨p⟩ in the Cyrillic script. They are transcribed in the International Phonetic Alphabet by upper- or lower-case variants of Roman ⟨R⟩, ⟨r⟩: ⟨r⟩, ⟨ɾ⟩, ⟨ɹ⟩, ⟨ɻ⟩, ⟨ʀ⟩, ⟨ʁ⟩, ⟨ɽ⟩, and ⟨ɺ⟩. Transcriptions for vocalic or semivocalic realisations of underlying rhotics include the ⟨ə̯⟩ and ⟨ɐ̯⟩.
Assimilation is a sound change in which some phonemes change to become more similar to other nearby sounds. A common type of phonological process across languages, assimilation can occur either within a word or between words.
In phonetics, a trill is a consonantal sound produced by vibrations between the active articulator and passive articulator. Standard Spanish ⟨rr⟩ as in perro, for example, is an alveolar trill.
The phonology of Catalan, a Romance language, has a certain degree of dialectal variation. Although there are two standard varieties, one based on Central Eastern dialect and another one based on South-Western or Valencian dialect, this article deals with features of all or most dialects, as well as regional pronunciation differences.
The phonology of the Hungarian language is notable for its process of vowel harmony, the frequent occurrence of geminate consonants and the presence of otherwise uncommon palatal stops.
The phonology of Italian describes the sound system—the phonology and phonetics—of Standard Italian and its geographical variants.
Compensatory lengthening in phonology and historical linguistics is the lengthening of a vowel sound that happens upon the loss of a following consonant, usually in the syllable coda, or of a vowel in an adjacent syllable. Lengthening triggered by consonant loss may be considered an extreme form of fusion. Both types may arise from speakers' attempts to preserve a word's moraic count.
In linguistics, assibilation is a sound change resulting in a sibilant consonant. It is a form of spirantization and is commonly the final phase of palatalization.
Ancient Greek phonology is the reconstructed phonology or pronunciation of Ancient Greek. This article mostly deals with the pronunciation of the standard Attic dialect of the fifth century BC, used by Plato and other Classical Greek writers, and touches on other dialects spoken at the same time or earlier. The pronunciation of Ancient Greek is not known from direct observation, but determined from other types of evidence. Some details regarding the pronunciation of Attic Greek and other Ancient Greek dialects are unknown, but it is generally agreed that Attic Greek had certain features not present in English or Modern Greek, such as a three-way distinction between voiced, voiceless, and aspirated stops ; a distinction between single and double consonants and short and long vowels in most positions in a word; and a word accent that involved pitch.
The phonological system of the Polish language is similar in many ways to those of other Slavic languages, although there are some characteristic features found in only a few other languages of the family, such as contrasting postalveolar and alveolo-palatal fricatives and affricates. The vowel system is relatively simple, with just six oral monophthongs and arguably two nasals in traditional speech, while the consonant system is much more complex.
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 Cypriot Greek § Phonology.
This article discusses the phonological system of the Czech language.
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 compared to articulation of before other vowels. This fronting is called palatalization.
In phonology, voicing is a sound change where a voiceless consonant becomes voiced due to the influence of its phonological environment; shift in the opposite direction is referred to as devoicing or desonorization. Most commonly, the change is a result of sound assimilation with an adjacent sound of opposite voicing, but it can also occur word-finally or in contact with a specific vowel.
A phonological rule is a formal way of expressing a systematic phonological or morphophonological process in linguistics. Phonological rules are commonly used in generative phonology as a notation to capture sound-related operations and computations the human brain performs when producing or comprehending spoken language. They may use phonetic notation or distinctive features or both.
In phonology, fronting is a sound change in which a vowel or consonant becomes fronted, advanced or pronounced farther to the front of the vocal tract than some reference point. The opposite situation, in which a sound becomes pronounced farther to the back of the vocal tract, is called backing or retraction. Fronting may be triggered by a nearby sound, in which case it is a form of assimilation, or may occur on its own.
