Obstruents
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; * affricates, which begin with complete occlusion but then release into a fricative-like release, such as . Voicing Obstruents are often prototypically voiceless, but voiced obstruents are common. This contrasts with sonorants, which are prototypically voiced and only rarely phonemically voiceless.

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 semivowels like and , nasal consonants like and , and liquid consonants 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 the consonantal subset—that is, nasals and liquids only, not vocoids (vowels and semivowels). Types Whereas obstruents are frequently voiceless, sonorants are almost always voiced. In the sonority hierarchy, all sounds higher than fricatives are sonorants. They can therefore form the nucleus of a syllable in languages that place that distinction at that level of sonority; see Syllable for details. Sonorants contrast with obs ...

Voiceless Consonant
In linguistics, voicelessness is the property of sounds being pronounced without the larynx vibrating. Phonologically, it is a type of phonation, which contrasts with other states of the larynx, but some object that the word phonation implies voicing and that voicelessness is the lack of phonation. The International Phonetic Alphabet (IPA) has distinct letters for many voiceless and modally voiced pairs of consonants (the obstruents), such as . Also, there are diacritics for voicelessness, and , which is used for letters with a descender. Diacritics are typically used with letters for prototypically voiced sounds, such as vowels and sonorant consonants: . In Russian use of the IPA, the voicing diacritic may be turned for voicelessness, e.g. . Voiceless vowels and other sonorants Sonorants are sounds such as vowels and nasals that are voiced in most of the world's languages. However, in some languages sonorants may be voiceless, usually allophonically. For example, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manner Of Articulation
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 or 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 inclu ...

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 ...

Speech Sound
In phonetics (a branch of linguistics), a phone is any distinct speech sound. It is any surface-level or unanalyzed sound of a language, the smallest identifiable unit occurring inside a stream of speech. In spoken human language, a phone is thus any vowel or consonant sound (or semivowel sound). In sign language, a phone is the equivalent of a unit of gesture. Phones versus phonemes Phones are the segments of speech that possess distinct physical or perceptual properties, regardless of whether the exact sound is critical to the meanings of words. Whereas a phone is a concrete sound used across various spoken languages, a phoneme is more abstract and narrowly defined: any class of phones that the users of a particular language nevertheless ''perceive'' as a single basic sound, a single unit, and that distinguishes words from other words. If a phoneme is swapped with another phoneme inside a word, it can change the meaning of that word, potentially changing that word into another w ...

Airflow
Airflow, or air flow, is the movement of air. Air behaves in a fluid manner, meaning particles naturally flow from areas of higher pressure to those where the pressure is lower. Atmospheric air pressure is directly related to altitude, temperature, and composition. In engineering, airflow is a measurement of the amount of air per unit of time that flows through a particular device. It can be described as a volumetric flow rate (volume of air per unit time) or a mass flow rate (mass of air per unit time). What relates both forms of description is the air density, which is a function of pressure and temperature through the ideal gas law. The flow of air can be induced through mechanical means (such as by operating an electric or manual fan) or can take place passively, as a function of pressure differentials present in the environment. Types of airflow Like any fluid, air may exhibit both laminar and turbulent flow patterns. Laminar flow occurs when air can flow smoothly, a ...

Consonant
In articulatory phonetics, a consonant is a speech sound that is articulated with complete or partial closure of the vocal tract, except for the h sound, which is pronounced without any stricture in the vocal tract. Examples are and [b], pronounced with the lips; and [d], pronounced with the front of the tongue; and [g], pronounced with the back of the tongue; , pronounced throughout the vocal tract; , [v], , and [z] pronounced by forcing air through a narrow channel (fricatives); and and , which have air flowing through the nose (nasal consonant, nasals). Most consonants are Pulmonic consonant, pulmonic, using air pressure from the lungs to generate a sound. Very few natural languages are non-pulmonic, making use of Ejective consonant, ejectives, Implosive consonant, implosives, and Click consonant, clicks. Contrasting with consonants are vowels. Since the number of speech sounds in the world's languages is much greater than the number of letters in any one alphabet, Linguis ...

Vowel
A vowel is a speech sound pronounced without any stricture in the vocal tract, forming the nucleus of a syllable. 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 Vowel length, quantity (length). They are usually voice (phonetics), voiced and are closely involved in Prosody (linguistics), prosodic variation such as tone (linguistics), tone, intonation (linguistics), intonation and Stress (linguistics), 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 (, , , , , and sometimes and ). Definition There are two complementary definitions of vowel, one Phonetics, phonetic and the other Phonology, phonological. *In the phonetic definition, a vowel is a sound, such as the English language, English "ah" or "oh" , produ ...

Fricative
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 lab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Affricate
An affricate is a consonant that begins as a stop and releases as a fricative, generally with the same place of articulation (most often coronal). It is often difficult to decide if a stop and fricative form a single phoneme or a consonant pair. English has two affricate phonemes, and , often spelled ''ch'' and ''j'', respectively. Examples The English sounds spelled "ch" and "j" ( broadly transcribed as and in the IPA), German and Italian ''z'' and Italian ''z'' are typical affricates, and sounds like these are fairly common in the world's languages, as are other affricates with similar sounds, such as those in Polish and Chinese. However, voiced affricates other than are relatively uncommon. For several places of articulation they are not attested at all. Much less common are labiodental affricates, such as in German, Kinyarwanda and Izi, or velar affricates, such as in Tswana (written ''kg'') or in High Alemannic Swiss German dialects.

Phoneme
A phoneme () is any set of similar Phone (phonetics), speech sounds that are perceptually regarded by the speakers of a language as a single basic sound—a smallest possible Phonetics, phonetic unit—that helps distinguish one word from another. All languages contain phonemes (or the spatial-gestural equivalent in sign languages), and all spoken languages include both consonant and vowel phonemes; phonemes are primarily studied under the branch of linguistics known as phonology. Examples and notation The English words ''cell'' and ''set'' have the exact same sequence of sounds, except for being different in their final consonant sounds: thus, versus in the International Phonetic Alphabet (IPA), a writing system that can be used to represent phonemes. Since and alone distinguish certain words from others, they are each examples of phonemes of the English language. Specifically they are consonant phonemes, along with , while is a vowel phoneme.
