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 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-syllabic vowel-lik ...

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 approximants and belong to the class of liquids, but lateral fricatives and affricates are also common in some parts of the world. Some languages, such as the Iwaidja and Ilgar languages of Australia, have lateral flaps, and others, such as the Xhosa and Zulu languages of Africa, have lateral clicks. When pronouncing the labiodental fricatives , the lip blocks the air ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alveolar Approximant
The voiced alveolar approximant is a type of consonantal sound used in some spoken languages. The symbol in the International Phonetic Alphabet that represents the alveolar and postalveolar approximants is , a lowercase letter ''r'' rotated 180 degrees. The equivalent X-SAMPA symbol is r\. The most common sound represented by the letter ''r'' in English is the voiced postalveolar approximant, pronounced a little more back and transcribed more precisely in IPA as , but is often used for convenience in its place. For further ease of typesetting, English phonemic transcriptions might use the symbol even though this symbol represents the alveolar trill in phonetic transcription. The bunched or molar r sounds remarkably similar to the postalveolar approximant and can be described as a ''voiced labial pre-velar approximant with tongue-tip retraction''. It can be transcribed in IPA as or . Features Features of the voiced alveolar approximant: Occurrence Alveolar Pos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Rhotic Consonant
In phonetics, rhotic consonants, or "R-like" sounds, are liquid consonants that are traditionally represented orthographically by symbols derived from the Greek letter rho, including , in the Latin script and , in the Cyrillic script. They are transcribed in the International Phonetic Alphabet by upper- or lower-case variants of Roman , : , , , , , , , and as well as by the lower-case turned Roman (the symbol for the near-open central vowel) combined with the "non-syllabic" diacritic, that is . This class of sounds is difficult to characterise phonetically; from a phonetic standpoint, there is no single articulatory correlate ( manner or place) common to rhotic consonants. Rhotics have instead been found to carry out similar phonological functions or to have certain similar phonological features across different languages. Being "R-like" is an elusive and ambiguous concept phonetically and the same sounds that function as rhotics in some systems may pattern with frica ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manner Of Articulation
In articulatory phonetics, the manner of articulation is the configuration and interaction of the articulators ( speech organs such as the tongue, lips, and palate) when making a speech sound. One parameter of manner is ''stricture,'' that is, how closely the speech organs approach one another. Others include those involved in the r-like sounds ( taps and trills), and the sibilancy of fricatives. The concept of manner is mainly used in the discussion of consonants, although the movement of the articulators will also greatly alter the resonant properties of the vocal tract, thereby changing the formant structure of speech sounds that is crucial for the identification of vowels. For consonants, the place of articulation and the degree of phonation of voicing are considered separately from manner, as being independent parameters. Homorganic consonants, which have the same place of articulation, may have different manners of articulation. Often nasality and laterality are i ...

Palatal Consonant
Palatals are consonants articulated with the body of the tongue raised against the hard palate (the middle part of the roof of the mouth). Consonants with the tip of the tongue curled back against the palate are called retroflex. Characteristics The most common type of palatal consonant is the extremely common approximant , which ranks as among the ten most common sounds in the world's languages. The nasal is also common, occurring in around 35 percent of the world's languages, in most of which its equivalent obstruent is not the stop , but the affricate . Only a few languages in northern Eurasia, the Americas and central Africa contrast palatal stops with postalveolar affricates—as in Hungarian, Czech, Latvian, Macedonian, Slovak, Turkish and Albanian. Consonants with other primary articulations may be palatalized, that is, accompanied by the raising of the tongue surface towards the hard palate. For example, English (spelled ''sh'') has such a palatal compone ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 appro ...

Postalveolar Consonant
Postalveolar or post-alveolar consonants are consonants articulated with the tongue near or touching the ''back'' of the alveolar ridge. Articulation is farther back in the mouth than the alveolar consonants, which are at the ridge itself, but not as far back as the hard palate, the place of articulation for palatal consonants. Examples of postalveolar consonants are the English palato-alveolar consonants , as in the words "ship", "'chill", "vision", and "jump", respectively. There are many types of postalveolar sounds—especially among the sibilants. The three primary types are '' palato-alveolar'' (such as , weakly palatalized), ''alveolo-palatal'' (such as , strongly palatalized), and '' retroflex'' (such as , unpalatalized). The palato-alveolar and alveolo-palatal subtypes are commonly counted as "palatals" in phonology since they rarely contrast with true palatal consonants. Postalveolar sibilants For most sounds involving the tongue, the place of articulation can be ... [...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 ...

Vowel
A vowel is a syllabic speech sound pronounced without any stricture in the vocal tract. 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 quantity (length). They are usually voiced and are closely involved in prosodic variation such as tone, intonation and 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 (a, e, i, o, u, and sometimes y). Definition There are two complementary definitions of vowel, one phonetic and the other phonological. *In the phonetic definition, a vowel is a sound, such as the English "ah" or "oh" , produced with an open vocal tract; it is median (the air escapes along the middle of the tongue), oral (at least some of the airflow must escape through the mouth), frictionless and continuant. ...
