The glottis is the opening between the vocal folds. The glottis is crucial in producing sound from the vocal folds.
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.
Phonetics is a branch of linguistics that studies how humans produce and perceive sounds or in the case of sign languages, the equivalent aspects of sign. Linguists who specialize in studying the physical properties of speech are phoneticians. The field of phonetics is traditionally divided into three sub-disciplines based on the research questions involved such as how humans plan and execute movements to produce speech, how various movements affect the properties of the resulting sound or how humans convert sound waves to linguistic information. Traditionally, the minimal linguistic unit of phonetics is the phone—a speech sound in a language which differs from the phonological unit of phoneme; the phoneme is an abstract categorization of phones and it is also defined as the smallest unit that discerns meaning between sounds in any given language.
Phonology is the branch of linguistics that studies how languages systematically organize their phones or, for sign languages, their constituent parts of signs. The term can also refer specifically to the sound or sign system of a particular language variety. At one time, the study of phonology related only to the study of the systems of phonemes in spoken languages, but may now relate to any linguistic analysis either:
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.
An affricate is a consonant that begins as a stop and releases as a fricative, generally with the same place of articulation. 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.
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.
The voiceless alveolar lateral fricative is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents voiceless dental, alveolar, and postalveolar lateral fricatives is, and the equivalent X-SAMPA symbol is K.
The voiceless epiglottal or pharyngeal trill, or voiceless epiglottal fricative, is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ʜ⟩, a small capital version of the Latin letter h, and the equivalent X-SAMPA symbol is H\.
The voiceless palatal fricative is a type of consonantal sound used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ç⟩, and the equivalent X-SAMPA symbol is C. It is the non-sibilant equivalent of the voiceless alveolo-palatal fricative.
A pharyngeal consonant is a consonant that is articulated primarily in the pharynx. Some phoneticians distinguish upper pharyngeal consonants, or "high" pharyngeals, pronounced by retracting the root of the tongue in the mid to upper pharynx, from (ary)epiglottal consonants, or "low" pharyngeals, which are articulated with the aryepiglottic folds against the epiglottis at the entrance of the larynx, as well as from epiglotto-pharyngeal consonants, with both movements being combined.
Abau is a Papuan language spoken in southern Sandaun Province of Papua New Guinea, primarily along the border with Indonesia.
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.
The voiced labial–velar nasal is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ŋ͡m⟩.
Laryngeal consonants are consonants with their primary articulation in the general region of the larynx. The laryngeal consonants comprise the pharyngeal consonants, the glottal consonants, and for some languages uvular consonants.
Idi is a Pahoturi language spoken in Western Province, Papua New Guinea. The so-called Pahoturi dialects form a dialect chain with Idi proper at one end and Agob proper at the other.
Kalkoti, also known as Goedijaa, is an Indo-Aryan language spoken in the Kalkot Tehsil, in the Upper Dir district in Pakistan.
The Cross-Linguistic Linked Data (CLLD) project coordinated over a dozen linguistics databases covering the languages of the world. It is hosted by the Department of Linguistic and Cultural Evolution at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany.
John Henry Esling, is a Canadian linguist specializing in phonetics. He is a Professor Emeritus of Linguistics at the University of Victoria, where he taught from 1981 to 2014. Esling was president of the International Phonetic Association from 2011 to 2015 and a co-editor of the 1999 Handbook of the International Phonetic Association.
