Phonological Process
A phonological rule is a formal way of expressing a systematic phonological or morphophonological process or diachronic sound change in language. 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. 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 (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 general, phonological rules start with the ''underlying represen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phonological
Phonology is the branch of linguistics that studies how languages or dialects systematically organize their sounds 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 may now 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 specifications for movement, location, and handshape. At first, a separate terminology was used for the study of sign phonology ('chereme' instead of 'phoneme', etc.), but the concepts are now considered to apply universally to all human languages. Terminology The word 'phonology' (as in 'phonology of English') can refer either to the field of study or to the phonological system of a given language. This is one of ...

Voiceless Alveolar Fricative
The voiceless alveolar fricatives are a type of fricative consonant pronounced with the tip or blade of the tongue against the alveolar ridge (gum line) just behind the teeth. This refers to a class of sounds, not a single sound. There are at least six types with significant perceptual differences: *The voiceless alveolar sibilant has a strong hissing sound, as the ''s'' in English ''sink''. It is one of the most common sounds in the world. *The voiceless denti-alveolar sibilant (an ''ad hoc'' notation), also called apico-dental, has a weaker lisping sound like English ''th'' in ''thin''. It occurs in Spanish dialects in southern Spain (eastern Andalusia). *The voiceless alveolar retracted sibilant ">Voiceless alveolar fricative#Voiceless alveolar retracted sibilant"> and the subform apico-alveolar , or called grave, has a weak hushing sound reminiscent of fricatives. It is used in the languages of northern Iberia, like Asturleonese, Basque, Castilian Spanish (excluding p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rewrite Rule
In mathematics, computer science, and logic, rewriting covers a wide range of methods of replacing subterms of a 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 relations on how to transform those objects. Rewriting can be 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 theorem provers and declarative programming languages are based on term rewriting. Example cases Logic In logic, the procedure for obtaining the conjunctive normal form (CNF) of a formula can be implemented as ...

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. That emphasis is typically caused by such properties as increased loudness and vowel length, full articulation of the vowel, and changes in 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'', 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 phonetic properties, such as loudness, vowel length, and pitch (which are also used for other linguistic functions), it is difficult to define ...

Vowel
A vowel is a syllabic speech sound pronounced without any stricture in the vocal tract. 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 quantity (length). They are usually voiced and are closely involved in prosodic variation such as tone, intonation and 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 (a, e, i, o, u, and sometimes y). Definition There are two complementary definitions of vowel, one phonetic and the other phonological. *In the phonetic definition, a vowel is a sound, such as the English "ah" or "oh" , produced with an open vocal tract; it is median (the air escapes along the middle of the tongue), oral (at least some of the airflow must escape through the mouth), frictionless and ...

International Phonetic Alphabet
The International Phonetic Alphabet (IPA) is an alphabetic system of phonetic transcription, 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.International Phonetic Association (IPA), ''Handbook''. The IPA is used by lexicography, lexicographers, foreign language students and teachers, linguistics, linguists, 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 wiktionary:lexical, lexical (and, to a limited extent, prosodic) sounds in oral language: phone (phonetics), phones, phonemes, Intonation (linguistics), intonation, and the separation of words and syllables. To represent additional qualities of speech—such as tooth wiktionary:gnash, gnashing, lisping, and sounds made wi ... [...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 which distinguishes dental and alveolar stops, Kota, Toda, Venda and some Irish dialects being a few of them. 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 ...

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 Extensions to the IPA have 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. Features He ...

Intervocalic Alveolar Flapping
Flapping or tapping, also known as alveolar flapping, intervocalic flapping, or ''t''-voicing, is a phonological process found in many varieties of English, especially North American, Cardiff, Ulster, Australian and New Zealand English, whereby 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 "posh" affricate and the "rough" glottal stop . In some varieties, , the voiced counterpart of , may also be 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'' sound similar or identical to ''winner''. Flapping of is sometimes perceived as the replacement of with ; for example, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
