Approximants
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-like segm ...

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 ...

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 ...

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] |
Semivowels
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.

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] |
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] |
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 ...

Speech Organ
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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sonorant
In phonetics and phonology, a sonorant or resonant is a speech sound that is produced with continuous, non-turbulent airflow in the vocal tract; these are the manners of articulation that are most often voiced in the world's languages. Vowels are sonorants, as are nasals like and , liquids like and , and semivowels like and . This set of sounds contrasts with the obstruents ( stops, affricates and fricatives). For some authors, only the term ''resonant'' is used with this broader meaning, while ''sonorant'' is restricted to consonants, referring to nasals and liquids but not vocoids (vowels and semivowels). Types Whereas obstruents are frequently voiceless, sonorants are almost always voiced. A typical sonorant consonant inventory found in many languages comprises the following: two nasals , two semivowels , and two liquids . In the sonority hierarchy, all sounds higher than fricatives are sonorants. They can therefore form the nucleus of a syllable in languages that ...

Phone (phonetics)
In phonetics and linguistics, a phone is any distinct speech sound or gesture, regardless of whether the exact sound is critical to the meanings of words. In contrast, a phoneme is a speech sound in a given language that, if swapped with another phoneme, could change one word to another. Phones are absolute and are not specific to any language, but phonemes can be discussed only in reference to specific languages. For example, the English words ''kid'' and ''kit'' end with two distinct phonemes, and , and swapping one for the other would change one word into a different word. However, the difference between the sounds in ''pun'' (, with aspiration) and ''spun'' (, without aspiration) never affects the meaning or identity of a word in English. Therefore, cannot be replaced with (or vice versa) and thereby convert one word to another. That causes and to be two distinct phones but not distinct phonemes in English. In contrast to English, swapping the same two sounds in Hindu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
R-colored Vowel
In phonetics, an r-colored or rhotic vowel (also called a retroflex vowel, vocalic r, or a rhotacized vowel) is a vowel that is modified in a way that results in a lowering in frequency of the third formant. R-colored vowels can be articulated in various ways: the tip or blade of the tongue may be turned up during at least part of the articulation of the vowel (a retroflex articulation) or the back of the tongue may be bunched. In addition, the vocal tract may often be constricted in the region of the epiglottis. R-colored vowels are exceedingly rare, occurring in less than one percent of all languages. However, they occur in two of the most widely spoken languages: North American English and Mandarin Chinese. In North American English, they are found in words such as ''dollar'', ''butter'', ''third'', ''color'', and ''nurse''. They also occur in Canadian French, some varieties of Portuguese, some Jutlandic dialects of Danish, as well as in a few indigenous languages of the ...

Formant
In speech science and phonetics, a formant is the broad spectral maximum that results from an acoustic resonance of the human vocal tract. In acoustics, a formant is usually defined as a broad peak, or local maximum, in the spectrum. For harmonic sounds, with this definition, the formant frequency is sometimes taken as that of the harmonic that is most augmented by a resonance. The difference between these two definitions resides in whether "formants" characterise the production mechanisms of a sound or the produced sound itself. In practice, the frequency of a spectral peak differs slightly from the associated resonance frequency, except when, by luck, harmonics are aligned with the resonance frequency. A room can be said to have formants characteristic of that particular room, due to its resonances, i.e., to the way sound reflects from its walls and objects. Room formants of this nature reinforce themselves by emphasizing specific frequencies and absorbing others, as exploited, ...
