Sonority Hierarchy
A sonority hierarchy or sonority scale is a hierarchical ranking of speech sounds (or phones). Sonority is loosely defined as the loudness of speech sounds relative to other sounds of the same pitch, length and stress, therefore sonority is often related to rankings for phones to their amplitude. For example, pronouncing the vowel [a] will produce a louder sound than the stop [t], so would rank higher in the hierarchy. However, grounding sonority in amplitude is not universally accepted. Instead, many researchers refer to sonority as the resonance of speech sounds. This relates to the degree to which production of phones results in vibrations of air particles. Thus, sounds that are described as more sonorous are less subject to masking by ambient noises. Sonority hierarchies are especially important when analyzing syllable structure; rules about what segments may appear in onsets or codas together, such as SSP, are formulated in terms of the difference of the ...

Speech Communication
Speech is a human vocal communication using language. Each language uses phonetic combinations of vowel and consonant sounds that form the sound of its words (that is, all English words sound different from all French words, even if they are the same word, e.g., "role" or "hotel"), and using those words in their semantic character as words in the lexicon of a language according to the syntactic constraints that govern lexical words' function in a sentence. In speaking, speakers perform many different intentional speech acts, e.g., informing, declaring, asking, persuading, directing, and can use enunciation, intonation, degrees of loudness, tempo, and other non-representational or paralinguistic aspects of vocalization to convey meaning. In their speech, speakers also unintentionally communicate many aspects of their social position such as sex, age, place of origin (through accent), physical states (alertness and sleepiness, vigor or weakness, health or illness), psychologica ...

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-like segmen ...

English Language
English is a West Germanic language of the Indo-European language family, with its earliest forms spoken by the inhabitants of early medieval England. It is named after the Angles, one of the ancient Germanic peoples that migrated to the island of Great Britain. Existing on a dialect continuum with Scots, and then closest related to the Low Saxon and Frisian languages, English is genealogically West Germanic. However, its vocabulary is also distinctively influenced by dialects of France (about 29% of Modern English words) and Latin (also about 29%), plus some grammar and a small amount of core vocabulary influenced by Old Norse (a North Germanic language). Speakers of English are called Anglophones. The earliest forms of English, collectively known as Old English, evolved from a group of West Germanic (Ingvaeonic) dialects brought to Great Britain by Anglo-Saxon settlers in the 5th century and further mutated by Norse-speaking Viking settlers starting in the 8th and 9th ...

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 ...

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] |
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 ...

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 ...

Flap Consonant
In phonetics, a flap or tap is a type of consonantal sound, which is produced with a single contraction of the muscles so that one articulator (such as the tongue) is thrown against another. Contrast with stops and trills The main difference between a tap or flap and a stop is that in a tap/flap there is no buildup of air pressure behind the place of articulation and consequently no release burst. Otherwise a tap/flap is similar to a brief stop. Taps and flaps also contrast with trills, where the airstream causes the articulator to vibrate. Trills may be realized as a single contact, like a tap or flap, but are variable, whereas a tap/flap is limited to a single contact. When a trill is brief and made with a single contact it is sometimes erroneously described as an (allophonic) tap/flap, but a true tap or flap is an active articulation whereas a trill is a passive articulation. That is, for a tap or flap the tongue makes an active gesture to contact the target place of articul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Close Vowel
A close vowel, also known as a high vowel (in U.S. terminology), is any in a class of vowel sounds used in many spoken languages. The defining characteristic of a close vowel is that the tongue is positioned as close as possible to the roof of the mouth as it can be without creating a constriction. A constriction would produce a sound that would be classified as a consonant. The term "close" is recommended by the International Phonetic Association. Close vowels are often referred to as "high" vowels, as in the Americanist phonetic tradition, because the tongue is positioned high in the mouth during articulation. In the context of the phonology of any particular language, a ''high vowel'' can be any vowel that is more close than a mid vowel. That is, close-mid vowels, near-close vowels, and close vowels can all be considered high vowels. Partial list The six close vowels that have dedicated symbols in the International Phonetic Alphabet are: * close front unrounded vowel * c ...

Mid Vowel
A mid vowel (or a true-mid vowel) is any in a class of vowel sounds used in some spoken languages. The defining characteristic of a mid vowel is that the tongue is positioned midway between an open vowel and a close vowel. Other names for a mid vowel are lowered close-mid vowel and raised open-mid vowel, though the former phrase may also be used to describe a vowel that is as low as open-mid; likewise, the latter phrase may also be used to describe a vowel that is as high as close-mid. Vowels The only mid vowel with a dedicated symbol in the International Phonetic Alphabet is the mid central vowel with ambiguous rounding . The IPA divides the vowel space into thirds, with the close-mid vowels such as or and the open-mid vowels such as or equidistant in formant space between open or and close or . Thus a true mid front unrounded vowel can be transcribed as either a lowered (with a lowering diacritic) or as a raised (with a raising diacritic). Typical truly mid vow ...

Open Vowel
An open vowel is a vowel sound in which the tongue is positioned as far as possible from the roof of the mouth. Open vowels are sometimes also called low vowels (in U.S. terminology ) in reference to the low position of the tongue. In the context of the phonology of any particular language, a ''low vowel'' can be any vowel that is more open than a mid vowel. That is, open-mid vowels, near-open vowels, and open vowels can all be considered low vowels. Partial list The open vowels with dedicated symbols in the International Phonetic Alphabet are: * open front unrounded vowel * open front rounded vowel This vowel is not known to occur as a phoneme distinct from in any language. * open back unrounded vowel * open back rounded vowel There also are central vowels that do not have dedicated symbols in the IPA: * open central unrounded vowel or (commonly written as if it were front) * open central rounded vowel There is no unambiguous way of transcribing the open central ...

Obstruent
An obstruent () is a speech sound such as , , or that is formed by ''obstructing'' airflow. Obstruents contrast with sonorants, which have no such obstruction and so resonate. All obstruents are consonants, but sonorants include vowels as well as consonants. Subclasses Obstruents are subdivided into plosives (oral stops), such as , with complete occlusion of the vocal tract, often followed by a release burst; fricatives, such as , with limited closure, not stopping airflow but making it turbulent; and affricates, which begin with complete occlusion but then release into a fricative-like release, such as .Zsiga, Elizabeth. ''The Sounds of Language: An Introduction to Phonetics and Phonology''. Wiley-Blackwell, 2013. Voicing Obstruents are often prototypically voiceless, but voiced obstruents are common. This contrasts with sonorants, which are prototypically voiced and only rarely voiceless. See also *List of phonetics topics A * Acoustic phonetics * Active articulato ...
