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.
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.
The term phonation has slightly different meanings depending on the subfield of phonetics. Among some phoneticians, phonation is the process by which the vocal folds produce certain sounds through quasi-periodic vibration. This is the definition used among those who study laryngeal anatomy and physiology and speech production in general. Phoneticians in other subfields, such as linguistic phonetics, call this process voicing, and use the term phonation to refer to any oscillatory state of any part of the larynx that modifies the airstream, of which voicing is just one example. Voiceless and supra-glottal phonations are included under this definition.
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 glottal stop or glottal plosive is a type of consonantal sound used in many spoken languages, produced by obstructing airflow in the vocal tract or, more precisely, the glottis. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ʔ⟩.
In phonetics, ejective consonants are usually voiceless consonants that are pronounced with a glottalic egressive airstream. In the phonology of a particular language, ejectives may contrast with aspirated, voiced and tenuis consonants. Some languages have glottalized sonorants with creaky voice that pattern with ejectives phonologically, and other languages have ejectives that pattern with implosives, which has led to phonologists positing a phonological class of glottalic consonants, which includes ejectives.
In phonetics, the airstream mechanism is the method by which airflow is created in the vocal tract. Along with phonation and articulation, it is one of three main components of speech production. The airstream mechanism is mandatory for most sound production and constitutes the first part of this process, which is called initiation.
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 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.
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.
In phonetics, a glottalic consonant is a consonant produced with some important contribution of the glottis.
Caddo is a Native American language, the traditional language of the Caddo Nation. It is critically endangered, with no exclusively Caddo-speaking community and as of 2023 only two speakers who had acquired the language as children outside school instruction, down from 25 speakers in 1997. Caddo has several mutually intelligible dialects. The most commonly used dialects are Hasinai and Hainai; others include Kadohadacho, Natchitoches and Yatasi.
This article describes those aspects of the phonological history of the English language which concern consonants.
Saanich is the language of the First Nations Saanich people in the Pacific Northwest region of northwestern North America. Saanich is a Coast Salishan language in the Northern Straits dialect continuum, the varieties of which are closely related to the Klallam language.
In English phonology, t-glottalization or t-glottalling is a sound change in certain English dialects and accents, particularly in the United Kingdom, that causes the phoneme to be pronounced as the glottal stop in certain positions. It is never universal, especially in careful speech, and it most often alternates with other allophones of such as, ,, , or.
The phonological system of the Hawaiian language is based on documentation from those who developed the Hawaiian alphabet during the 1820s as well as scholarly research conducted by lexicographers and linguists from 1949 to present.
Debuccalization or deoralization is a sound change or alternation in which an oral consonant loses its original place of articulation and moves it to the glottis. The pronunciation of a consonant as is sometimes called aspiration, but in phonetics, aspiration is the burst of air accompanying a stop. The word comes from Latin bucca, meaning "cheek" or "mouth".
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.
Glottalized clicks are click consonants pronounced with closure of the glottis. All click types have glottalized variants. They are very common: All of the Khoisan languages of Africa have them, as does Dahalo and the Bantu languages Yeyi and Xhosa. They are produced by making a glottal stop, which stops the flow of air, and then using the front of the tongue to make the click sound in the middle of the glottal stop.
The creaky-voiced glottal approximant is a consonant sound in some languages. In the IPA, it is transcribed as ⟨ʔ̞⟩, ⟨ʔ̰⟩, or ⟨ʔ̬⟩. It involves tension in the glottis and diminution of airflow, compared to surrounding vowels, but not full occlusion.
