Proto-Dené–Caucasian Language
Proto-Dené–Caucasian is the reconstructed hypothetical common ancestor of the Dené–Caucasian languages, a proposed language superfamily to which Basque, North Caucasian, Burushaski, Sino-Tibetan, Yeniseian, Na-Dené and possibly also other language families may belong. Dene-Caucasian is not supported by most historical linguists and is generally regarded as a fringe theory. Reconstructed phonology As with Proto-Indo-European and Proto-Uralic, linguists working on reconstructions of the Proto-Dené–Caucasian language usually do not use the IPA. To facilitate comparisons with the literature, Starostin's transcription (largely identical to Bengtson's) is used in this section, followed by the IPA equivalents between slashes (for phonemes) or brackets (for actual phones). It differs from the IPA especially in the affricates, each of which is written with a single character, and the laterals. This convention strongly resembles the APA. As in all reconstructions of proto- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dené–Caucasian Languages
Dené–Caucasian is a proposed language family that includes widely-separated language groups spoken in the Northern Hemisphere: Sino-Tibetan languages, Yeniseian languages, Burushaski and North Caucasian languages in Asia; Na-Dené languages in North America; and the Vasconic languages from Europe (including Basque). A narrower connection specifically between North American Na-Dené and Siberian Yeniseian (the Dené–Yeniseian languages hypothesis) was proposed by Edward Vajda in 2008, and has met with some acceptance within the community of professional linguists. The validity of the rest of the family, however, is viewed as doubtful or rejected by nearly all historical linguists. History of the hypothesis Classifications similar to Dené–Caucasian were put forward in the 20th century by Alfredo Trombetti, Edward Sapir, Robert Bleichsteiner, Karl Bouda, E. J. Furnée, René Lafon, Robert Shafer, Olivier Guy Tailleur, Morris Swadesh, Vladimir N. Toporov, and other scho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bilabial Consonant
In phonetics, a bilabial consonant is a labial consonant articulated with both lips. Frequency Bilabial consonants are very common across languages. Only around 0.7% of the world's languages lack bilabial consonants altogether, including Tlingit, Chipewyan, Oneida, and Wichita. Varieties The bilabial consonants identified by the International Phonetic Alphabet (IPA) are: Owere Igbo has a six-way contrast among bilabial stops: . Other varieties The extensions to the IPA also define a () for smacking the lips together. A lip-smack in the non-percussive sense of the lips noisily parting would be .Heselwood (2013: 121) The IPA chart shades out ''bilabial lateral consonants'', which is sometimes read as indicating that such sounds are not possible. The fricatives and are often lateral, but since no language makes a distinction for centrality, the allophony is not noticeable.

Voiced Consonant
Voice or voicing is a term used in phonetics and phonology to characterize speech sounds (usually consonants). Speech sounds can be described as either voiceless (otherwise known as ''unvoiced'') or voiced. The term, however, is used to refer to two separate concepts: *Voicing can refer to the ''articulatory process'' in which the vocal folds vibrate, its primary use in phonetics to describe phones, which are particular speech sounds. *It can also refer to a classification of speech sounds that tend to be associated with vocal cord vibration but may not actually be voiced at the articulatory level. That is the term's primary use in phonology: to describe phonemes; while in phonetics its primary use is to describe phones. For example, voicing accounts for the difference between the pair of sounds associated with the English letters "s" and "z". The two sounds are transcribed as and to distinguish them from the English letters, which have several possible pronunciations, depe ...

Ejective Consonant
In phonetics, ejective consonants are usually voiceless consonants that are pronounced with a glottalic egressive airstream. In the phonology of a particular language, ejectives may contrast with 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 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 raise, 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 pronounced. In the languages in which they are more obvious, ejectives are often des ...

Aspiration (phonetics)
In phonetics, aspiration is the strong burst of breathing, breath that accompanies either the release or, in the case of preaspiration, the Stop consonant#articulation, closure of some obstruents. In English, aspirated consonants are allophones in complementary distribution#In phonology, complementary distribution with their unaspirated counterparts, but in some other languages, notably most Languages of South Asia, South Asian languages (including Languages of India, Indian) and East Asian languages, the difference is Contrastive distribution#Phonology, contrastive. In dialects with aspiration, to feel or see the difference between aspirated and unaspirated sounds, one can put a hand or a lit candle in front of one's mouth, and say ''spin'' and then ''pin'' . One should either feel a puff of air or see a flicker of the candle flame with ''pin'' that one does not get with ''spin''. Transcription In the International Phonetic Alphabet (IPA), aspirated consonants are written usi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plosives
In phonetics, a plosive, also known as an occlusive or simply a stop, is a pulmonic consonant in which the vocal tract is blocked so that all airflow ceases. The occlusion may be made with the tongue tip or blade (, ), tongue body (, ), lips (, ), or glottis (). Plosives contrast with nasals, where the vocal tract is blocked but airflow continues through the nose, as in and , and with fricatives, where partial occlusion impedes but does not block airflow in the vocal tract. Terminology The terms ''stop, occlusive,'' and ''plosive'' are often used interchangeably. Linguists who distinguish them may not agree on the distinction being made. The terms refer to different features of the consonant. "Stop" refers to the airflow that is stopped. "Occlusive" refers to the articulation, which occludes (blocks) the vocal tract. "Plosive" refers to the release burst (plosion) of the consonant. Some object to the use of "plosive" for inaudibly released stops, which may then instead be ca ...

Lateral Consonant
A lateral is a consonant in which the airstream proceeds along one or both of the sides of the tongue, but it is blocked by the tongue from going through the middle of the mouth. An example of a lateral consonant is the English ''L'', as in ''Larry''. Lateral consonants contrast with central consonants, in which the airstream flows through the center of the mouth. For the most common laterals, the tip of the tongue makes contact with the upper teeth (see dental consonant) or the upper gum (see alveolar consonant), but there are many other possible places for laterals to be made. The most common laterals are approximant Approximants are speech sounds that involve the articulators approaching each other but not narrowly enough nor with enough articulatory precision to create turbulent airflow. Therefore, approximants fall between fricatives, which do produce a ...s and belong to the class of liquid consonant, liquids, but lateral fricative consonant, fricatives and affricate co ...

Central Consonant
A central consonant, also known as a median consonant, is a consonant sound that is produced when air flows across the center of the mouth over the tongue. The class contrasts with lateral consonants, in which air flows over the sides of the tongue rather than down its center. Examples of central consonants are the voiced alveolar fricative (the "z" in the English word "zoo") and the palatal approximant (the "y" in the English word "yes"). Others are the central fricatives , the central approximants , the trills , and the central flaps . The term is most relevant for approximants and fricatives (for which there are contrasting lateral and central consonants - e.g. versus and versus ). Stops that have "lateral release" can be written in the International Phonetic Alphabet using a superscript symbol, e.g. , or can be implied by a following lateral consonant, e.g. . The labial fricatives often—perhaps usually—have lateral airflow, as occlusion between the teeth and lips block ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glottal Consonant
Glottal consonants are consonants using the glottis as their primary articulation. Many phoneticians consider them, or at least the glottal fricative, to be transitional states of the glottis without a point of articulation as other consonants have, while some do not consider them to be consonants at all. However, glottal consonants behave as typical consonants in many languages. For example, in Literary Arabic, most words are formed from a root ''C-C-C'' consisting of three consonants, which are inserted into templates such as or . The glottal consonants and can occupy any of the three root consonant slots, just like "normal" consonants such as or . The glottal consonants in the International Phonetic Alphabet are as follows: Characteristics In many languages, the "fricatives" are not true fricatives. This is a historical usage of the word. They instead represent transitional states of the glottis ( phonation) without a specific place of articulation, and may behave as ...

Pharyngeal Consonant
A pharyngeal consonant is a consonant that is articulated primarily in the pharynx. Some phoneticians distinguish upper pharyngeal consonants, or "high" pharyngeals, pronounced by retracting the root of the tongue in the mid to upper pharynx, from (ary)epiglottal consonants, or "low" pharyngeals, which are articulated with the aryepiglottic folds against the epiglottis at the entrance of the larynx, as well as from epiglotto-pharyngeal consonants, with both movements being combined. Stops and trills can be reliably produced only at the epiglottis, and fricatives can be reliably produced only in the upper pharynx. When they are treated as distinct places of articulation, the term ''radical consonant'' may be used as a cover term, or the term ''guttural consonants'' may be used instead. In many languages, pharyngeal consonants trigger advancement of neighboring vowels. Pharyngeals thus differ from uvulars, which nearly always trigger retraction. For example, in some dialects of ...

Uvular Consonant
Uvulars are consonants articulated with the back of the tongue against or near the uvula, that is, further back in the mouth than velar consonants. Uvulars may be stops, fricatives, nasals, trills, or approximants, though the IPA does not provide a separate symbol for the approximant, and the symbol for the voiced fricative is used instead. Uvular affricates can certainly be made but are rare: they occur in some southern High-German dialects, as well as in a few African and Native American languages. (Ejective uvular affricates occur as realizations of uvular stops in Lillooet, Kazakh, or as allophonic realizations of the ejective uvular fricative in Georgian.) Uvular consonants are typically incompatible with advanced tongue root, and they often cause retraction of neighboring vowels. Uvular consonants in IPA The uvular consonants identified by the International Phonetic Alphabet are: , being/existence , - !χʼ , uvular ejective fricative , Tlingit , x̱'aan , ''χʼàː ...

Velar Consonant
Velars are consonants articulated with the back part of the tongue (the dorsum) against the soft palate, the back part of the roof of the mouth (known also as the velum). Since the velar region of the roof of the mouth is relatively extensive and the movements of the dorsum are not very precise, velars easily undergo assimilation, shifting their articulation back or to the front depending on the quality of adjacent vowels. They often become automatically ''fronted'', that is partly or completely palatal before a following front vowel, and ''retracted'', that is partly or completely uvular before back vowels. Palatalised velars (like English in ''keen'' or ''cube'') are sometimes referred to as palatovelars. Many languages also have labialized velars, such as , in which the articulation is accompanied by rounding of the lips. There are also labial–velar consonants, which are doubly articulated at the velum and at the lips, such as . This distinction disappears with the approx ...
