Proto-Tai Language
Proto-Tai is the reconstructed proto-language (common ancestor) of all the Tai languages, including modern Lao, Shan, Tai Lü, Tai Dam, Ahom, Northern Thai, Standard Thai, Bouyei, and Zhuang. The Proto-Tai language is not directly attested by any surviving texts, but has been reconstructed using the comparative method. It was reconstructed in 1977 by Li Fang-KueiLi, Fang-Kuei. (1977).

Labial Consonant
Labial consonants are consonants in which one or both lips are the active articulator. The two common labial articulations are bilabials, articulated using both lips, and labiodentals, articulated with the lower lip against the upper teeth, both of which are present in English. A third labial articulation is dentolabials, articulated with the upper lip against the lower teeth (the reverse of labiodental), normally only found in pathological speech. Generally precluded are linguolabials, in which the tip of the tongue contacts the posterior side of the upper lip, making them coronals, though sometimes, they behave as labial consonants. The most common distribution between bilabials and labiodentals is the English one, in which the nasal and the stops, , , and , are bilabial and the fricatives, , and , are labiodental. The voiceless bilabial fricative, voiced bilabial fricative, and the bilabial approximant do not exist as the primary realizations of any sounds in English, bu ...

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.''Phonetics for communication disorders.'' Martin J. Ball and Nicole Müller. Routledge, 2005. 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 ...

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 the consonants ''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, while proposes that it should be considered one. In the International Phonet ...

Liquid Consonant
In phonetics, liquids are a class of consonants consisting of voiced lateral approximants like together with rhotics like . Etymology The grammarian Dionysius Thrax used the Ancient Greek word (, ) to describe the sonorant consonants () of classical Greek. Most commentators assume that this referred to their "slippery" effect on meter in classical Greek verse when they occur as the second member of a consonant cluster. This word was calqued into Latin as , whence it has been retained in the Western European phonetic tradition. Phonological properties Liquids as a class often behave in a similar way in the phonotactics of a language: for example, they often have the greatest freedom in occurring in consonant clusters. Metathesis Cross-linguistically, liquids are the consonants most prone to metathesis. Spanish In Spanish, /r/ is liable for metathesis. More specifically, /r/ and /l/ frequently switch places: * Lat. ''crocodīlus'' > Span. ''cocodrilo'' “crocodile” * L ... [...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, Icelandic and ...

Fricative Consonant
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. "Strident" could mean just "sibilant", but some authors include also labiodental and uvular fricatives in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glottalization
Glottalization is the complete or partial closure of the glottis during the articulation of another sound. Glottalization of vowels and other sonorants is most often realized as creaky voice (partial closure). Glottalization of obstruent consonants usually involves complete closure of the glottis; another way to describe this phenomenon is to say that a glottal stop is made simultaneously with another consonant. In certain cases, the glottal stop can even wholly replace the voiceless consonant. The term 'glottalized' is also used for ejective and implosive consonants; see glottalic consonant for examples. There are two other ways to represent glottalization of sonorants in the IPA: (a) the same way as ejectives, with an apostrophe; or (b) with the under-tilde for creaky voice. For example, the Yapese word for "sick" with a glottalized ''m'' could be transcribed as either or . (In some typefaces, the apostrophe will occur above the m.) Types Glottalization varies along three p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aspirated Consonant
In phonetics, aspiration is the strong burst of breath that accompanies either the release or, in the case of preaspiration, the closure of some obstruents. In English, aspirated consonants are allophones in complementary distribution with their unaspirated counterparts, but in some other languages, notably most South Asian languages (including Indian) and East Asian languages, the difference is 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 using the symbols for voiceless consonants followed by the aspiration modifier letter , a superscript form of the symbol for the voiceless glottal fricative .

Voice (phonetics)
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 ...

Stop Consonant
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 ...

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 ...
