ISO 11940-2
ISO 11940-2 is an ISO standard for a simplified transcription of the Thai language into Latin characters. The full standard includes pronunciation rules and conversion tables of Thai consonants and vowels. It is a sequel to , describing a way to transform its transliteration into a broad transcription. Principle The standard (to be renamed ) defines a strict and reversible transliteration of Thai orthography into Latin characters, by means of a host of diacritics. The result bears no resemblance to Thai pronunciation. The additional standard describes a set of rules to transform the transliteration resulting from based on Thai orthography into a broad transcription based on pronunciation, using only unadorned Latin letters. All information on vowel length and syllable tone is dropped, as well as the distinction between IPA and . The standard explicitly mentions that whenever the full pronunciation of each word is necessary or needed, conversion of long vowels can be devised ...

ISO 11940
ISO 11940 is an ISO standard for the transliteration of Thai characters, published in 1998, updated in September 2003, and confirmed in 2008. An extension to this standard, named ISO 11940-2, defines a simplified transcription based on it. Consonants The transliteration of the pure consonants is derived from their usual pronunciation as an initial consonant. An unmarked ''h'' is used to form digraphs denoting aspirated consonants. High and low pairs of consonants are systematically differentiated by applying a macron to the high class consonant. Further differentiation of consonants with identical phonetic function is obtained by leaving the most frequent unmarked, marking the second commonest by a dot below, marking the third commonest by a horn, and marking the fourth commonest by underlining. The use of a dot below has a similar effect to the Indological practice of distinguishing retroflex consonants by a dot below, but there are subtle differences – it is the transl ...

Alveolar Consonant
Alveolar consonants (; UK also ) are articulated with the tongue against or close to the superior alveolar ridge, which is called that because it contains the alveoli (the sockets) of the upper teeth. Alveolar consonants may be articulated with the tip of the tongue (the apical consonants), as in English, or with the flat of the tongue just above the tip (the "blade" of the tongue; called laminal consonants), as in French and Spanish. The International Phonetic Alphabet (IPA) does not have separate symbols for the alveolar consonants. Rather, the same symbol is used for all coronal places of articulation that are not palatalized like English palato-alveolar ''sh'', or retroflex. To disambiguate, the ''bridge'' (, ''etc.'') may be used for a dental consonant, or the under-bar (, ''etc.'') may be used for the postalveolars. differs from dental in that the former is a sibilant and the latter is not. differs from postalveolar in being unpalatalized.

Thai Alphabet
The Thai script (, , ) is the abugida used to write Thai, Southern Thai and many other languages spoken in Thailand. The Thai script itself (as used to write Thai) has 44 consonant symbols (, ), 16 vowel symbols (, ) that combine into at least 32 vowel forms, four tone diacritics ( or , or ), and other diacritics. Although commonly referred to as the ''Thai alphabet'', the script is not a true alphabet but an abugida, a writing system in which the full characters represent consonants with diacritical marks for vowels; the absence of a vowel diacritic gives an implied 'a' or 'o'. Consonants are written horizontally from left to right, and vowels following a consonant in speech are written above, below, to the left or to the right of it, or a combination of those. History The Thai script is derived from the Sukhothai script, which itself is derived from the Old Khmer script (, ''akson khom''), which is a southern Brahmic style of writing derived from the south Indian Pa ...

Nasal Stop
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, Iceland ...

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 * ...

Approximant Consonant
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 turbulent airstream, and vowels, which produce no turbulence. This class is composed of sounds like (as in ''rest'') and semivowels like and (as in ''yes'' and ''west'', respectively), as well as lateral approximants like (as in ''less''). Terminology Before Peter Ladefoged coined the term ''approximant'' in the 1960s, the terms ''frictionless continuant'' and ''semivowel'' were used to refer to non-lateral approximants. In phonology, ''approximant'' is also a distinctive feature that encompasses all sonorants except nasals, including vowels, taps, and trills. Semivowels Some approximants resemble vowels in acoustic and articulatory properties and the terms ''semivowel'' and ''glide'' are often used for these non-syllabi ...

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 for non-sibilant fricatives. "Strident" could mean just "sibilant", but some authors include also labiod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 pronuncia ...

Aspirated Consonant
In phonetics, aspiration is a 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 and East Asian languages, the difference is contrastive. Transcription In the 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 ... (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 . For instance, represents the voiceless bilabial stop, and represents the aspirat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tenuis Consonant
In linguistics, a tenuis consonant ( or ) is an obstruent that is voiceless, unaspirated and unglottalized. In other words, it has the "plain" phonation of with a voice onset time close to zero (a zero-VOT consonant), as Spanish ''p, t, ch, k'' or English ''p, t, k'' after ''s'' (''spy, sty, sky''). For most languages, the distinction is relevant only for stops and affricates. However, a few languages have analogous series for fricatives. Mazahua, for example, has ejective, aspirated, and voiced fricatives alongside tenuis , parallel to stops alongside tenuis . Many click languages have tenuis click consonants alongside voiced, aspirated, and glottalized series. Transcription In transcription, tenuis consonants are not normally marked explicitly, and consonants written with voiceless IPA letters, such as , are typically assumed to be unaspirated and unglottalized unless otherwise indicated. However, aspiration is often left untranscribed if no contrast needs to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. "Stop" refers to the stopping of the airflow, "occlusive" to the articulation which occludes (blocks) the vocal tract, and "plosive" to the plosion (release burst) of the consonant. Some object to the use of "plosive" for inaudibly released stops, which may then instead be called "applosives". The International Phonetic Association and ...
