AllophoneIn phonology, an allophone (ˈæləfoʊn; from the Greek ἄλλος, , 'other' and φωνή, , 'voice, sound') is one of multiple possible spoken sounds - or phones - or signs used to pronounce a single phoneme in a particular language. For example, in English, the voiceless plosive t (as in stop [ˈstɒp]) and the aspirated form th (as in top [ˈthɒp]) are allophones for the phoneme /t/, while these two are considered to be different phonemes in some languages such as Thai.
Velar consonantVelars are consonants articulated with the back part of the tongue (the dorsum) against the soft palate, the back part of the roof of the mouth (also known as the “velum”). Since the velar region of the roof of the mouth is relatively extensive and the movements of the dorsum are not very precise, velars easily undergo assimilation, shifting their articulation back or to the front depending on the quality of adjacent vowels.
Manner of articulationIn 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.
Nasal consonantIn 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 [n], [ŋ] and [m], 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.
Lateral consonantA lateral is a consonant in which the airstream proceeds along one or both of the sides of the tongue, but it is blocked by the tongue from going through the middle of the mouth. An example of a lateral consonant is the English L, as in Larry. Lateral consonants contrast with central consonants, in which the airstream flows through the center of the mouth. For the most common laterals, the tip of the tongue makes contact with the upper teeth (see dental consonant) or the upper gum (see alveolar consonant), but there are many other possible places for laterals to be made.
Australian Aboriginal languagesThe Indigenous languages of Australia number in the hundreds, the precise number being quite uncertain, although there is a range of estimates from a minimum of around 250 (using the technical definition of 'language' as non-mutually intelligible varieties) up to possibly 363. The Indigenous languages of Australia comprise numerous language families and isolates, perhaps as many as 13, spoken by the Indigenous peoples of mainland Australia and a few nearby islands.
Linguolabial consonantLinguolabials or apicolabials are consonants articulated by placing the tongue tip or blade against the upper lip, which is drawn downward to meet the tongue. They represent one extreme of a coronal articulatory continuum which extends from linguolabial to subapical palatal places of articulation. Cross-linguistically, linguolabial consonants are very rare, but they do not represent a particularly exotic combination of articulatory configurations, unlike click consonants or ejectives.
Voiced labiodental flapIn phonetics, the voiced labiodental flap is a speech sound found primarily in languages of Central Africa, such as Kera and Mangbetu. It has also been reported in the Austronesian language Sika. It is one of the few non-rhotic flaps. The sound begins with the lower lip placed behind the upper teeth. The lower lip is then flipped outward, striking the upper teeth in passing. The symbol in the International Phonetic Alphabet that represents this sound is ⱱ, which resembles Cyrillic izhitsa, , but is composed of a V and the hook of the flap ɾ.
Dahalo languageDahalo is an endangered Cushitic language spoken by around 500-600 Dahalo people on the coast of Kenya, near the mouth of the Tana River. Dahalo is unusual among the world's languages in using all four airstream mechanisms found in human language - clicks, implosives, ejectives, and regular consonants. While the language is known primarily as “Dahalo” to linguists, the term itself is an exonym supposedly used by Aweer-speakers that itself essentially means “stupid” or “worthless”.
X-SAMPAThe Extended Speech Assessment Methods Phonetic Alphabet (X-SAMPA) is a variant of SAMPA developed in 1995 by John C. Wells, professor of phonetics at University College London. It is designed to unify the individual language SAMPA alphabets, and extend SAMPA to cover the entire range of characters in the 1993 version of International Phonetic Alphabet (IPA). The result is a SAMPA-inspired remapping of the IPA into 7-bit ASCII. SAMPA was devised as a hack to work around the inability of text encodings to represent IPA symbols.
