In phonetics, contour describes speech sounds that behave as single segments but make an internal transition from one quality, place, or manner to another. Such sounds may be tones, vowels, or consonants.
Many tone languages have contour tones , which move from one level to another. For example, Mandarin Chinese has four lexical tones. The high tone is level, without contour; the falling tone is a contour from high pitch to low; the rising tone a contour from mid pitch to high, and, when spoken in isolation, the low tone takes on a dipping contour, mid to low and then to high pitch. They are transcribed with series of either diacritics or tone letters, which with proper font support fuse into an iconic shape: [ma˨˩˦].
In the case of vowels, the terms diphthong and triphthong are used instead of 'contour'. They are vowels that glide from one place of articulation to another, as in English boy and bow. They are officially transcribed with a non-syllabic sign under one of the vowel letters: [bɔɪ̯], [baʊ̯]. However, when there is no chance of confusion, the diacritic is often omitted for simplicity.
The most common contour consonants are by far the affricates [ citation needed ], such as English ch and j. They start out as one manner, a stop, and release into a different manner, a fricative, but behave as single consonants: [t͡ʃ], [d͡ʒ]. Other types of transition are attested in consonants, such as prenasalized stops in many African languages and nasal release in Slavic languages, the retroflex trill [ɽr] of Toda, the trilled affricate [ʈ͡r] of Fijian, voicing contours [d͡tʰ], [ɡ͡k͡xʼ] in ǃXóõ, [1] and even click contours (airstream contours) in Khoisan languages such as Nǁng, which start with a lingual (velaric) airstream mechanism and release with either a pulmonic mechanism ( linguo-pulmonic clicks such as [ǃ͡q], [ǂ͡χ]) or an ejective mechanism ( linguo-glottalic clicks such as [ǃʼ], [ǂ͡χʼ]).

Click consonants, or clicks, are speech sounds that occur as consonants in many languages of Southern Africa and in three languages of East Africa. Examples familiar to English-speakers are the tut-tut or tsk! tsk! used to express disapproval or pity, the tchick! used to spur on a horse, and the clip-clop! sound children make with their tongue to imitate a horse trotting.
The International Phonetic Alphabet (IPA) is an alphabetic system of phonetic notation based primarily on the Latin script. It was devised by the International Phonetic Association in the late 19th century as a standardized representation of speech sounds in written form. The IPA is used by lexicographers, foreign language students and teachers, linguists, speech–language pathologists, singers, actors, constructed language creators, and translators.
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 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.
Velars are consonants articulated with the back part of the tongue against the soft palate, the back part of the roof of the mouth.
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 voiced labial–palatalapproximant is a type of consonantal sound, used in some spoken languages. It has two constrictions in the vocal tract: with the tongue on the palate, and rounded at the lips. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɥ⟩, a rotated lowercase letter ⟨h⟩, or occasionally ⟨jʷ⟩, which indicates with a different kind of rounding.
The palatal or palato-alveolar clicks are a family of click consonants found, as components of words, only in southern Africa. The tongue is nearly flat, and is pulled back rather than down as in the postalveolar clicks, making a sharper sound than those consonants. The tongue makes an extremely broad contact across the roof of the mouth, making correlation with the places of articulation of non-clicks difficult, but Ladefoged & Traill (1984:18) find that the primary place of articulation is the palate, and say that "there is no doubt that should be described as a palatal sound".
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.
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.
Juǀʼhoan, also known as Southern or Southeastern ǃKung or ǃXun, is the southern variety of the ǃKung dialect continuum, spoken in northeastern Namibia and the Northwest District of Botswana by San Bushmen who largely identify themselves as Juǀʼhoansi. Several regional dialects are distinguished: Epukiro, Tsumǃkwe, Rundu, Omatako and ǂKxʼauǁʼein, with Tsumǃkwe being the best described and often taken as representative.
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 voiceless palato-alveolar sibilant affricate or voiceless domed postalveolar sibilant affricate is a type of consonantal sound used in some spoken languages. The sound is transcribed in the International Phonetic Alphabet with ⟨t͡ʃ ⟩, ⟨t͜ʃ ⟩⟨tʃ ⟩, or, in broad transcription, ⟨c⟩. The alternative commonly used in American tradition is ⟨č⟩. It is familiar to English speakers as the "ch" sound in "chip".
Americanist phonetic notation, also known as the North American Phonetic Alphabet (NAPA), the Americanist Phonetic Alphabet or the American Phonetic Alphabet (APA), is a system of phonetic notation originally developed by European and American anthropologists and language scientists for the phonetic and phonemic transcription of indigenous languages of the Americas and for languages of Europe. It is still commonly used by linguists working on, among others, Slavic, Uralic, Semitic languages and for the languages of the Caucasus, of India, and of much of Africa; however, Uralists commonly use a variant known as the Uralic Phonetic Alphabet.
Doubly articulated consonants are consonants with two simultaneous primary places of articulation of the same manner. They are a subset of co-articulated consonants. They are to be distinguished from co-articulated consonants with secondary articulation; that is, a second articulation not of the same manner. An example of a doubly articulated consonant is the voiceless labial-velar plosive, which is a and a pronounced simultaneously. On the other hand, the voiceless labialized velar plosive has only a single stop articulation, velar, with a simultaneous approximant-like rounding of the lips. In some dialects of Arabic, the voiceless velar fricative has a simultaneous uvular trill, but this is not considered double articulation either.
Pulmonic-contour clicks, also called sequential linguo-pulmonic consonants, are consonants that transition from a click to an ordinary pulmonic sound, or more precisely, have an audible delay between the front and rear release of the click. All click types have linguo-pulmonic variants, which occur as both stops and affricates, and are attested in four phonations: tenuis, voiced, aspirated, and murmured. At least a voiceless linguo-pulmonic affricate is attested from all Khoisan languages of southern Africa, as well as (reportedly) from the Bantu language Yeyi from the same area, but they are unattested elsewhere.
Ejective-contour clicks, also called sequential linguo-glottalic consonants, are consonants that transition from a click to an ejective sound, or more precisely, have an audible delay between the front and rear release of the click. All click types have linguo-glottalic variants, which occur as both stops and affricates, and may be voiced. At least a voiceless linguo-glottalic affricate is attested from all Khoisan languages of southern Africa, as well as from the Bantu language Yeyi from the same area, but they are unattested elsewhere.
The voiced upper-pharyngeal plosive or stop is a rare consonant.
