Phonological Rule
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 Language production, producing or Language comprehension, comprehending spoken language. They may use phonetic notation or distinctive features or both. John Goldsmith (linguist), John Goldsmith (1995) defines phonological rules as mappings between two different levels of sounds representation—in this case, the abstract or underlying level and the surface level—and Bruce Hayes (linguist), Bruce Hayes (2009) describes them as "generalizations" about the different ways a sound can be pronounced in different environments. That is to say, phonological rules describe how a speaker goes from the abstract representation stored in their brain, to the actual sound they articulate when they speak. In ...

Phonological
Phonology (formerly also phonemics or phonematics: "phonemics ''n.'' 'obsolescent''1. Any procedure for identifying the phonemes of a language from a corpus of data. 2. (formerly also phonematics) A former synonym for phonology, often preferred by the American Structuralists and reflecting the importance in structuralist work of phonemics in sense 1.": "phonematics ''n.'' 1. 'obsolete''An old synonym for phonemics (sense 2).") is the branch of linguistics that studies how languages systematically organize their phonemes or, for sign languages, their constituent parts of signs. The term can also refer specifically to the sound or sign system of a particular language variety. At one time, the study of phonology related only to the study of the systems of phonemes in spoken languages, but now it may relate to any linguistic analysis either: Sign languages have a phonological system equivalent to the system of sounds in spoken languages. The building blocks of signs are sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Historical Linguistics
Historical linguistics, also known as diachronic linguistics, is the scientific study of how languages change over time. It seeks to understand the nature and causes of linguistic change and to trace the evolution of languages. Historical linguistics involves several key areas of study, including the reconstruction of ancestral languages, the classification of languages into families, ( comparative linguistics) and the analysis of the cultural and social influences on language development. This field is grounded in the uniformitarian principle, which posits that the processes of language change observed today were also at work in the past, unless there is clear evidence to suggest otherwise. Historical linguists aim to describe and explain changes in individual languages, explore the history of speech communities, and study the origins and meanings of words ( etymology). Development Modern historical linguistics dates to the late 18th century, having originally grown o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intervocalic Tapping Phonological Rule
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 and Australian English) that, impressionistically speaking, replaces /t/ with /d/. For example, "''metal''" is pronounced ; "''batter''" sounds like . (More precisely, both /t/ and /d/ are pronounced as the alveolar tap .) In North American English, the weakening is variable across word boundaries, such that the /t/ of "see you tomorrow" might be pronounced as either or . Some languages have intervocalic-weakening processes fully active word-internally and in connected discourse. For example, in Spanish Spanish might refer to: * Items from or related to Spain: **Spaniards are a nation and ethnic group indigenous to S ...

Rewrite Rule
In mathematics, computer science, and logic, rewriting covers a wide range of methods of replacing subterms of a well-formed formula, formula with other terms. Such methods may be achieved by rewriting systems (also known as rewrite systems, rewrite engines, or reduction systems). In their most basic form, they consist of a set of objects, plus Relation (mathematics), relations on how to transform those objects. Rewriting can be non-deterministic algorithm, non-deterministic. One rule to rewrite a term could be applied in many different ways to that term, or more than one rule could be applicable. Rewriting systems then do not provide an algorithm for changing one term to another, but a set of possible rule applications. When combined with an appropriate algorithm, however, rewrite systems can be viewed as computer programs, and several automated theorem proving, theorem provers and declarative programming languages are based on term rewriting. Example cases Logic In logic, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stress (linguistics)
In linguistics, and particularly phonology, stress or accent is the relative emphasis or prominence given to a certain syllable in a word or to a certain word in a phrase or Sentence (linguistics), sentence. That emphasis is typically caused by such properties as increased loudness and vowel length, full articulation of the vowel, and changes in Tone (linguistics), tone. The terms ''stress'' and ''accent'' are often used synonymously in that context but are sometimes distinguished. For example, when emphasis is produced through pitch alone, it is called ''Pitch-accent language, pitch accent'', and when produced through length alone, it is called ''quantitative accent''. When caused by a combination of various intensified properties, it is called ''stress accent'' or ''dynamic accent''; English uses what is called ''variable stress accent''. Since stress can be realised through a wide range of Phonetics, phonetic properties, such as loudness, vowel length, and pitch (which are ...

Vowel
A vowel is a speech sound pronounced without any stricture in the vocal tract, forming the nucleus of a syllable. Vowels are one of the two principal classes of speech sounds, the other being the consonant. Vowels vary in quality, in loudness and also in Vowel length, quantity (length). They are usually voice (phonetics), voiced and are closely involved in Prosody (linguistics), prosodic variation such as tone (linguistics), tone, intonation (linguistics), intonation and Stress (linguistics), stress. The word ''vowel'' comes from the Latin word , meaning "vocal" (i.e. relating to the voice). In English, the word ''vowel'' is commonly used to refer both to vowel sounds and to the written symbols that represent them (, , , , , and sometimes and ). Definition There are two complementary definitions of vowel, one Phonetics, phonetic and the other Phonology, phonological. *In the phonetic definition, a vowel is a sound, such as the English language, English "ah" or "oh" , produ ...

International Phonetic Alphabet
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 standard written representation for the sounds of speech. The IPA is used by linguists, lexicography, lexicographers, foreign language students and teachers, speech–language pathology, speech–language pathologists, singers, actors, constructed language creators, and translators. The IPA is designed to represent those qualities of speech that are part of lexical item, lexical (and, to a limited extent, prosodic) sounds in oral language: phone (phonetics), phones, Intonation (linguistics), intonation and the separation of syllables. To represent additional qualities of speechsuch as tooth wikt:gnash, gnashing, lisping, and sounds made with a cleft lip and cleft palate, cleft palatean extensions to the International Phonetic Alphabet, extended set of symbols may be used ...

Alveolar Tap
The voiced alveolar tap or flap is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents a dental consonant, dental, alveolar consonant, alveolar, or postalveolar consonant, postalveolar tap and flap consonants, tap or flap is . The terms ''tap'' and ''flap'' are often used interchangeably. Peter Ladefoged proposed the distinction that a tap strikes its point of contact directly, as a very brief stop, and a flap strikes the point of contact tangentially: "Flaps are most typically made by retracting the tongue tip behind the alveolar ridge and moving it forward so that it strikes the ridge in passing." That distinction between the alveolar tap and flap can be written in the IPA with tap and flap , the 'retroflex' symbol being used for the one that starts with the tongue tip curled back behind the alveolar ridge. The distinction is noticeable in the speech of some American English speakers in distinguishing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flap Consonant
In phonetics, a flap or tap is a type of consonantal sound, which is produced with a single contraction of the muscles so that one articulator (such as the tongue) is thrown against another. Contrast with stops and trills The main difference between a tap or flap and a stop is that in a tap/flap there is no buildup of air pressure behind the place of articulation and consequently no release burst. Otherwise a tap/flap is similar to a brief stop. Taps and flaps also contrast with trills, where the airstream causes the articulator to vibrate. Trills may be realized as a single contact, like a tap or flap, but are variable, whereas a tap/flap is limited to a single contact. When a trill is brief and made with a single contact it is sometimes erroneously described as an (allophonic) tap/flap, but a true tap or flap is an active articulation whereas a trill is a passive articulation. That is, for a tap or flap the tongue makes an active gesture to contact the target place of artic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Voiced Alveolar Plosive
The voiced alveolar, dental and postalveolar plosives (or stops) are types of consonantal sounds used in many spoken languages. The symbol in the International Phonetic Alphabet that represents voiced dental, alveolar, and postalveolar plosives is (although the symbol can be used to distinguish the dental plosive, and the postalveolar), and the equivalent X-SAMPA symbol is d. There are only a few languages that distinguish dental and alveolar stops, among them Kota, Toda, Venda and some Irish dialects. Features Features of the voiced alveolar stop: * There are three specific variants of : ** Dental, which means it is articulated with either the tip or the blade of the tongue at the upper teeth, termed respectively '' apical'' and ''laminal''. ** Denti-alveolar, which means it is articulated with the blade of the tongue at the alveolar ridge, and the tip of the tongue behind upper teeth. ** Alveolar, which means it is articulated with either the tip or the blade ...

Voiceless Alveolar Plosive
The voiceless alveolar, dental and postalveolar plosives (or stops) are types of consonantal sounds used in almost all spoken languages. The symbol in the International Phonetic Alphabet that represents voiceless dental, alveolar, and postalveolar plosives is , and the equivalent X-SAMPA symbol is t. The voiceless dental plosive can be distinguished with the underbridge diacritic, and the postalveolar with a retraction line, , and the extIPA has a double underline diacritic which can be used to explicitly specify an alveolar pronunciation, . The sound is a very common sound cross-linguistically. Most languages have at least a plain , and some distinguish more than one variety. Some languages without a are colloquial Samoan (which also lacks an ), Abau, and Nǁng of South Africa. There are only a few languages which distinguish dental and alveolar stops, Kota, Toda, Venda and many Australian Aboriginal languages being a few of them; certain varieties of Hiberno-En ...

Intervocalic Alveolar Flapping
Flapping or tapping, also known as alveolar flapping, intervocalic flapping, or ''t''-voicing, is a phonological process involving a voiced alveolar tap or flap; it is found in many varieties of English, especially North American, Cardiff, Ulster, Australian and New Zealand English, where the voiceless alveolar stop consonant phoneme is pronounced as a voiced alveolar flap , a sound produced by briefly tapping the alveolar ridge with the tongue, when placed between vowels. In London English, the flapped is perceived as a casual pronunciation intermediate between the affricate , with higher class associations, and the glottal stop , with lower class associations. In these named varieties, outside of Britain, , the voiced counterpart of , is also frequently pronounced as a flap in such positions, making pairs of words like ''latter'' and ''ladder'' sound similar or identical. In similar positions, the combination may be pronounced as a nasalized flap , making ''winter'' soun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
