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.
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.
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, rhotic consonants, or "R-like" sounds, are liquid consonants that are traditionally represented orthographically by symbols derived from the Greek letter rho, including ⟨R⟩, ⟨r⟩ in the Latin script and ⟨Р⟩, ⟨p⟩ in the Cyrillic script. They are transcribed in the International Phonetic Alphabet by upper- or lower-case variants of Roman ⟨R⟩, ⟨r⟩: ⟨r⟩, ⟨ɾ⟩, ⟨ɹ⟩, ⟨ɻ⟩, ⟨ʀ⟩, ⟨ʁ⟩, ⟨ɽ⟩, and ⟨ɺ⟩. Transcriptions for vocalic or semivocalic realisations of underlying rhotics include the ⟨ə̯⟩ and ⟨ɐ̯⟩.
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.
Postalveolar (post-alveolar) consonants are consonants articulated with the tongue near or touching the back of the alveolar ridge. Articulation is farther back in the mouth than the alveolar consonants, which are at the ridge itself, but not as far back as the hard palate, the place of articulation for palatal consonants. Examples of postalveolar consonants are the English palato-alveolar consonants, as in the words "ship", "'chill", "vision", and "jump", respectively.
A retroflex, apico-domal, or cacuminalconsonant is a coronal consonant where the tongue has a flat, concave, or even curled shape, and is articulated between the alveolar ridge and the hard palate. They are sometimes referred to as cerebral consonants—especially in Indology.
The voiceless retroflex sibilant fricative is a type of consonantal sound used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ʂ⟩ which is a Latin letter s combined with a retroflex hook. Like all the retroflex consonants, the IPA letter is formed by adding a rightward-pointing hook to the bottom of ⟨s⟩. A distinction can be made between laminal, apical, and sub-apical articulations. Only one language, Toda, appears to have more than one voiceless retroflex sibilant, and it distinguishes subapical palatal from apical postalveolar retroflex sibilants; that is, both the tongue articulation and the place of contact on the roof of the mouth are different.
In phonetics, a trill is a consonantal sound produced by vibrations between the active articulator and passive articulator. Standard Spanish ⟨rr⟩ as in perro, for example, is an alveolar trill.
In phonetics, a flap or tap is a type of consonantal sound, which is produced with a single contraction of the muscles so that one articulator is thrown against another.
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. An archetypal nasal sound is.
Guttural R is the phenomenon whereby a rhotic consonant is produced in the back of the vocal tract rather than in the front portion thereof and thus as a guttural consonant. Speakers of languages with guttural R typically regard guttural and coronal rhotics to be alternative pronunciations of the same phoneme, despite articulatory differences. Similar consonants are found in other parts of the world, but they often have little to no cultural association or interchangeability with coronal rhotics and are (perhaps) not rhotics at all.
The voiced retroflex trill is not a single consonant quality but a sliding cluster sound within the time of a single segment. It has been reported in Toda and confirmed with laboratory measurements. Peter Ladefoged transcribes it with the IPA symbol that is normally associated with the retroflex flap, ⟨ɽ⟩. Although the tongue starts out in a subapical retroflex position, trilling involves the tip of the tongue and causes it to move forward to the alveolar ridge. Thus, the retroflex trill gives a preceding vowel retroflex coloration, like other retroflex consonants, but the vibration itself is not much different from an alveolar trill. Thus, the narrower transcription ⟨ɽr⟩ is also appropriate.
South Dravidian is one of the four major branches of the Dravidian languages family. It includes the literary languages Tamil, Kannada, Malayalam and Tulu, as well as several non-literary languages such as Badaga, Irula, Kota, Kurumba, Toda and Kodava.
Murray Barnson Emeneau was the founder of the Department of Linguistics at the University of California, Berkeley.
Tamil phonology is characterised by the presence of "true-subapical" retroflex consonants and multiple rhotic consonants. Its script does not distinguish between voiced and unvoiced consonants; phonetically, voice is assigned depending on a consonant's position in a word, voiced intervocalically and after nasals except when geminated. Tamil phonology permits few consonant clusters, which can never be word initial.
Kota is a language of the Dravidian family with about 900 native speakers in the Nilgiri hills of Tamil Nadu state, India. It is spoken mainly by the tribal Kota people (India). In the late 1800s, the native speaking population was about 1,100. In 1990, the population was only 930, out of an ethnic population of perhaps 1,400, despite the great increase in the population of the area. The language is 'critically endangered' due to the greater social status of neighbouring languages. The Kota language may have originated from Tamil-Kannada and is closely related to Toda language. The Kota population is about 2500. The origin of the name Kota is derived from the Dravidian root word 'Ko' meaning Mountain. Traditionally Kota and Toda are seen as from a single branch Toda-Kota which separated from Tamil-Kota but recently Krishnamurti considers it to have diverged first from Tamil-Kota and later Toda as it doesn't have the centralized vowels characterized for Tamil-Toda.
The voiceless alveolar trill differs from the voiced alveolar trill only by the vibrations of the vocal cord. It occurs in a few languages, usually alongside the voiced version, as a similar phoneme or an allophone.
Konda-Dora, also known simply as Konda or Kubi, is a Dravidian language spoken in India. It is spoken by the scheduled tribe of the Konda-Dora, who mostly live in the districts of Vizianagaram, Srikakulam, and East Godavari in Andhra Pradesh, and the Koraput district in Odisha.
