Distinctive Features
In linguistics, a distinctive feature is the most basic unit of phonology, phonological structure that distinguishes one Phone (phonetics), sound from another within a language. For example, the feature [+Voice (phonetics), voice] ''distinguishes'' the two bilabial plosives: [p] and [b] (i.e., it makes the two plosives ''distinct'' from one another). There are many different ways of defining and arranging features into ''feature systems'': some deal with only one language while others are developed to apply to all languages. Distinctive features are grouped into categories according to the natural classes of segment (linguistics), segments they describe: major class features, laryngeal features, manner features, and place features. These feature categories in turn are further specified on the basis of the phonetics, phonetic properties of the segments in question. Since the inception of the phonological analysis of distinctive features in the 1950s, features traditionally have be ...

Linguistics
Linguistics is the scientific study of language. The areas of linguistic analysis are syntax (rules governing the structure of sentences), semantics (meaning), Morphology (linguistics), morphology (structure of words), phonetics (speech sounds and equivalent gestures in sign languages), phonology (the abstract sound system of a particular language, and analogous systems of sign languages), and pragmatics (how the context of use contributes to meaning). Subdisciplines such as biolinguistics (the study of the biological variables and evolution of language) and psycholinguistics (the study of psychological factors in human language) bridge many of these divisions. Linguistics encompasses Outline of linguistics, many branches and subfields that span both theoretical and practical applications. Theoretical linguistics is concerned with understanding the universal grammar, universal and Philosophy of language#Nature of language, fundamental nature of language and developing a general ...

Syllable
A syllable is a basic unit of organization within a sequence of speech sounds, such as within a word, typically defined by linguists as a ''nucleus'' (most often a vowel) with optional sounds before or after that nucleus (''margins'', which are most often consonants). In phonology and studies of languages, syllables are often considered the "building blocks" of words. They can influence the rhythm of a language, its prosody, its poetic metre; properties such as stress, tone and reduplication operate on syllables and their parts. Speech can usually be divided up into a whole number of syllables: for example, the word ''ignite'' is made of two syllables: ''ig'' and ''nite''. Most languages of the world use relatively simple syllable structures that often alternate between vowels and consonants. Despite being present in virtually all human languages, syllables still have no precise definition that is valid for all known languages. A common criterion for finding syllable bound ...

Vocal Folds
In humans, the vocal cords, also known as vocal folds, are folds of throat tissues that are key in creating sounds through Speech, vocalization. The length of the vocal cords affects the pitch of voice, similar to a violin string. Open when breathing and vibrating for speech or singing, the folds are controlled via the recurrent laryngeal nerve, recurrent laryngeal branch of the vagus nerve. They are composed of twin infoldings of mucous membrane stretched horizontally, from back to front, across the larynx. They vibration, vibrate, modulating the flow of air being expelled from the lungs during phonation. The 'true vocal cords' are distinguished from the 'false vocal folds', known as vestibular folds or ''ventricular folds'', which sit slightly superior to the more delicate true folds. These have a minimal role in normal phonation, but can produce deep sonorous tones, screams and growls. The length of the vocal fold at birth is approximately six to eight millimeters and grows t ...

Consonants
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 sound, which is pronounced without any stricture in the vocal tract. Examples are and pronounced with the lips; and pronounced with the front of the tongue; and pronounced with the back of the tongue; , pronounced throughout the vocal tract; , , 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. Since the number of speech sounds in the world's languages is much greater than the number of letters in any one alphabet, linguists have devised systems such as the International Phonetic Alphabet (IPA) to assign a unique and un ...

Sonorant
In phonetics and phonology, a sonorant or resonant is a speech sound that is produced with continuous, non-turbulent airflow in the vocal tract; these are the manners of articulation that are most often voiced in the world's languages. Vowels are sonorants, as are semivowels like and , nasal consonants like and , and liquid consonants like and . This set of sounds contrasts with the obstruents ( stops, affricates and fricatives). For some authors, only the term ''resonant'' is used with this broader meaning, while ''sonorant'' is restricted to the consonantal subset—that is, nasals and liquids only, not vocoids (vowels and semivowels). Types Whereas obstruents are frequently voiceless, sonorants are almost always voiced. In the sonority hierarchy, all sounds higher than fricatives are sonorants. They can therefore form the nucleus of a syllable in languages that place that distinction at that level of sonority; see Syllable for details. Sonorants contrast with obs ...

Trill Consonant
In phonetics, a trill is a consonantal sound manner of articulation, produced by vibrations between the active articulator and passive articulator. Standard Spanish as in , for example, is an alveolar trill. A trill is made by the articulator being held in place and the airstream causing it to vibrate. Usually a trill vibrates for 2–3 contacts, but may be up to 5, or even more if geminate consonant, geminate. However, trills may also be produced with only one contact. While single-contact trills are similar to Flap consonant, taps and flaps, a tap or flap differs from a trill in that it is made by a muscular contraction rather than airstream. Individuals with ankyloglossia may have issues producing the trill sound. Phonemic trills Trill consonants included in the International Phonetic Alphabet: * – Voiced alveolar trill * – Voiceless alveolar trill * – Voiced bilabial trill * – Voiceless bilabial trill * – Voiced retroflex trill * – Voiced uvular trill * ...

Liquid Consonant
In linguistics, a liquid consonant or simply liquid is any of a class of consonants that consists of rhotics and voiced lateral approximants, which are also sometimes described as "R-like sounds" and "L-like sounds". The word ''liquid'' seems to be a calque of the Ancient Greek word (; ), initially used by grammarian Dionysius Thrax to describe Greek sonorants. Liquid consonants are more prone to be part of consonant clusters and of the syllable nucleus. Their third formants are generally non-predictable based on the first two formants. Another important feature is their complex articulation, which makes them a hard consonant class to study with precision and the last consonants to be produced by children during their phonological development. They are also more likely to undergo certain types of phonological changes such as assimilation, dissimilation and metathesis. Most languages have at least one liquid in their phonemic inventory. English has two, and . His ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Nasal Consonant
In phonetics, a nasal, also called a nasal occlusive or nasal stop in contrast with an oral stop or nasalized consonant, is an occlusive consonant produced with a lowered velum, allowing air to escape freely through the nose. The vast majority of consonants are oral consonants. Examples of nasals in English are , and , in words such as ''nose'', ''bring'' and ''mouth''. Nasal occlusives are nearly universal in human languages. There are also other kinds of nasal consonants in some languages. Definition Nearly all nasal consonants are nasal occlusives, in which air escapes through the nose but not through the mouth, as it is blocked (occluded) by the lips or tongue. The oral cavity still acts as a resonance chamber for the sound. Rarely, non-occlusive consonants may be nasalized. Most nasals are voiced, and in fact, the nasal sounds and are among the most common sounds cross-linguistically. Voiceless nasals occur in a few languages such as Burmese, Welsh, Icelan ...

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; * affricates, which begin with complete occlusion but then release into a fricative-like release, such as . Voicing Obstruents are often prototypically voiceless In linguistics, voicelessness is the property of sounds being pronounced without the larynx vibrating. Phonologically, it is a type of phonation, which contrasts with other states of the larynx, but some object that the word phonation implies v ..., but voiced obstruents are common. This contrasts with sonorant ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Vocal Tract
The vocal tract is the cavity in human bodies and in animals where the sound produced at the sound source (larynx in mammals; syrinx in birds) is filtered. In birds, it consists of the trachea, the syrinx, the oral cavity, the upper part of the esophagus, and the beak. In mammals, it consists of the laryngeal cavity, the pharynx, the oral cavity, and the nasal cavity. The estimated average length of the vocal tract in men is 16.9 cm and 14.1 cm in women.

Semivowel
In phonetics and phonology, a semivowel, glide or semiconsonant is a sound that is phonetically similar to a vowel sound but functions as the syllable boundary, rather than as the nucleus of a syllable. Examples of semivowels in English are ''y'' and ''w'' in ''yes'' and ''west'', respectively. Written in IPA, ''y'' and ''w'' are near to the vowels ''ee'' and ''oo'' in ''seen'' and ''moon,'' written in IPA. The term ''glide'' may alternatively refer to any type of transitional sound, not necessarily a semivowel. Classification Semivowels form a subclass of approximants. Although "semivowel" and "approximant" are sometimes treated as synonymous, most authors use the term "semivowel" for a more restricted set; there is no universally agreed-upon definition, and the exact details may vary from author to author. For example, do not consider the labiodental approximant to be a semivowel. In the International Phonetic Alphabet, the diacritic attached to non-syllabic vowel lett ...
