In phonology, an allophone is one of multiple possible spoken sounds – or phones – used to pronounce a single phoneme in a particular language. For example, in English, the voiceless plosive and the aspirated form are allophones for the phoneme, while these two are considered to be different phonemes in some languages such as Central Thai. Similarly, in Spanish, and are allophones for the phoneme, while these two are considered to be different phonemes in English.
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 and semivowels like and, as well as lateral approximants like.
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, 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, pronounced by forcing air through a narrow channel (fricatives); and and, which have air flowing through the nose (nasals). Most consonants are pulmonic, using air pressure from the lungs to generate a sound. Very few natural languages are non-pulmonic, making use of ejectives, implosives, and clicks. Contrasting with consonants are vowels.
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 ; or the side of the tongue against the molars, in the case of Welsh. This turbulent airflow is called frication.
Liquids are a class of consonants that consists of rhotics and voiced lateral approximants, sometimes described as "r-like sounds" and "l-like sounds". The word liquid seems to be a calque of the Ancient Greek word ὑγρός, initially used by grammarian Dionysius Thrax to describe Greek sonorants.
In articulatory phonetics, the manner of articulation is the configuration and interaction of the articulators 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, and the sibilancy of fricatives.
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.
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.
Uvulars are consonants articulated with the back of the tongue against or near the uvula, that is, further back in the mouth than velar consonants. Uvulars may be stops, fricatives, nasals, trills, or approximants, though the IPA does not provide a separate symbol for the approximant, and the symbol for the voiced fricative is used instead. Uvular affricates can certainly be made but are rare: they occur in some southern High-German dialects, as well as in a few African and Native American languages. Uvular consonants are typically incompatible with advanced tongue root, and they often cause retraction of neighboring vowels.
Voice or voicing is a term used in phonetics and phonology to characterize speech sounds. Speech sounds can be described as either voiceless or voiced.
In phonetics, nasalization is the production of a sound while the velum is lowered, so that some air escapes through the nose during the production of the sound by the mouth. Examples of archetypal nasal sounds include and.
Implosive consonants are a group of stop consonants with a mixed glottalic ingressive and pulmonic egressive airstream mechanism. That is, the airstream is controlled by moving the glottis downward in addition to expelling air from the lungs. Therefore, unlike the purely glottalic ejective consonants, implosives can be modified by phonation. Contrastive implosives are found in approximately 13% of the world's languages.
The phonology of Japanese features a phonemic inventory including five vowels and 12 or more consonants. The phonotactics are relatively simple, allowing for few consonant clusters. Japanese phonology has been affected by the presence of several layers of vocabulary in the language: in addition to native Japanese vocabulary, Japanese has a large amount of Chinese-based vocabulary and loanwords from other languages.
The phonological system of the Polish language is similar in many ways to those of other Slavic languages, although there are some characteristic features found in only a few other languages of the family, such as contrasting postalveolar and alveolo-palatal fricatives and affricates. The vowel system is relatively simple, with just six oral monophthongs and arguably two nasals in traditional speech, while the consonant system is much more complex.
In articulatory phonetics, fortition, also known as strengthening, is a consonantal change that increases the degree of stricture. It is the opposite of the more common lenition. For example, a fricative or an approximant may become a stop. Although not as typical of sound change as lenition, fortition may occur in prominent positions, such as at the beginning of a word or stressed syllable; as an effect of reducing markedness; or due to morphological leveling.
This article is a technical description of the phonetics and phonology of Korean. Unless otherwise noted, statements in this article refer to South Korean standard language based on the Seoul dialect.
Unlike many languages, Icelandic has only very minor dialectal differences in sounds. The language has both monophthongs and diphthongs, and many consonants can be voiced or unvoiced.
Iaai is a language of Ouvéa Island. It shares the island of Ouvéa with Fagauvea, a Polynesian outlier language.
This article is about the sound system of the Navajo language. The phonology of Navajo is intimately connected to its morphology. For example, the entire range of contrastive consonants is found only at the beginning of word stems. In stem-final position and in prefixes, the number of contrasts is drastically reduced. Similarly, vowel contrasts found outside of the stem are significantly neutralized. For details about the morphology of Navajo, see Navajo grammar.
