Consonant
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 [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 [z] pronounced by forcing air through a narrow channel (fricatives); and and , which have air flowing through the nose (nasal consonant, nasals). Most consonants are Pulmonic consonant, pulmonic, using air pressure from the lungs to generate a sound. Very few natural languages are non-pulmonic, making use of Ejective consonant, ejectives, Implosive consonant, implosives, and Click consonant, 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, Linguis ...

Ejective Consonant
In phonetics, ejective consonants are usually voiceless consonants that are pronounced with a Airstream mechanism#Glottalic initiation, glottalic egressive airstream. In the phonology of a particular language, ejectives may contrast with Aspirated consonant, aspirated, voiced and tenuis consonants. Some languages have glottalized sonorants with creaky voice that pattern with ejectives phonologically, and other languages have ejectives that pattern with Implosive consonant, implosives, which has led to phonologists positing a phonological class of glottalic consonants, which includes ejectives. Description In producing an ejective, the stylohyoid muscle and digastric muscle contract, causing the hyoid bone and the connected glottis to rise, and the forward articulation (at the velum in the case of ) is held, raising air pressure greatly in the mouth so when the oral articulators separate, there is a dramatic burst of air. The Adam's apple may be seen moving when the sound is prono ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 ...

Articulatory Phonetics
The field of articulatory phonetics is a subfield of phonetics that studies articulation and ways that humans produce speech. Articulatory phoneticians explain how humans produce speech sounds via the interaction of different physiological structures. Generally, articulatory phonetics is concerned with the transformation of aerodynamic energy into acoustic energy. Aerodynamic energy refers to the airflow through the vocal tract. Its potential form is air pressure; its kinetic form is the actual dynamic airflow. Acoustic energy is variation in the air pressure that can be represented as sound waves, which are then perceived by the human auditory system as sound. Respiratory sounds can be produced by expelling air from the lungs. However, to vary the sound quality in a way useful for speaking, two speech organs normally move towards each other to contact each other to create an obstruction that shapes the air in a particular fashion. The point of maximum obstruction is called ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Syllable Nucleus
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 bounda ...

English Orthography
English orthography comprises the set of rules used when writing the English language, allowing readers and writers to associate written graphemes with the sounds of spoken English, as well as other features of the language. English's orthography includes norms for spelling, hyphenation, capitalisation, word, word breaks, Emphasis (typography), emphasis, and punctuation. As with the orthographies of most other world languages, written English is broadly standardised. This standardisation began to develop when movable type spread to England in the late 15th century. However, unlike with most languages, there are multiple ways to spell every phoneme, and most grapheme, letters also represent multiple pronunciations depending on their position in a word and the context. This is partly due to the large number of words that have been Loanword, loaned from a large number of other languages throughout the history of English, without successful attempts at complete English-language spe ...

Implosive Consonant
Implosive consonants are a group of stop consonants (and possibly also some affricates) with a mixed glottalic ingressive and pulmonic egressive airstream mechanism. That is, the airstream is controlled by moving the glottis downward in addition to expelling air from the lungs. Therefore, unlike the purely glottalic ejective consonants, implosives can be modified by phonation. Contrastive implosives are found in approximately 13% of the world's languages. In the International Phonetic Alphabet, implosives are indicated by modifying the top of a letter (voiced stop) with a rightward-facing hook: . Articulation During the occlusion of the stop, pulling the glottis downward rarefies the air in the vocal tract. The stop is then released. In languages whose implosives are particularly salient, that may result in air rushing into the mouth before it flows out again with the next vowel. To take in air sharply in that way is to implode a sound. However, probably more typically, there ... [...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 ...

Fricative
A fricative is a consonant produced by forcing air through a narrow channel made by placing two articulators close together. These may be the lower lip against the upper teeth, in the case of ; the back of the tongue against the soft palate in the case of German (the final consonant of '' Bach''); or the side of the tongue against the molars, in the case of Welsh (appearing twice in the name '' Llanelli''). This turbulent airflow is called frication. A particular subset of fricatives are the sibilants. When forming a sibilant, one still is forcing air through a narrow channel, but in addition, the tongue is curled lengthwise to direct the air over the edge of the teeth. English , , , and are examples of sibilants. The usage of two other terms is less standardized: "Spirant" is an older term for fricatives used by some American and European phoneticians and phonologists for non-sibilant fricatives. "Strident" could mean just "sibilant", but some authors include also lab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digraph (orthography)
A digraph () or digram is a pair of character (symbol), characters used in the orthography of a language to write either a single phoneme (distinct sound), or a sequence of phonemes that does not correspond to the normal values of the two characters combined. Some digraphs represent phonemes that cannot be represented with a single character in the writing system of a language, like in Spanish ''chico'' and ''ocho''. Other digraphs represent phonemes that can also be represented by single characters. A digraph that shares its pronunciation with a single character may be a relic from an earlier period of the language when the digraph had a different pronunciation, or may represent a distinction that is made only in certain dialects, like the English . Some such digraphs are used for purely etymology, etymological reasons, like in French. In some orthographies, digraphs (and occasionally trigraph (orthography), trigraphs) are considered individual letter (alphabet), letters, w ...
