Niellim Language
The Niellim language (autonym ''lwaà'') is a Bua language spoken by some 5,000 people (as of 1993) along the Chari River in southern Chad. It is mainly spoken in two areas: one around the city of Sarh (to which many - perhaps most - speakers have migrated) and one, its traditional home, further north, between about 9°30′ and 9°50′ N, corresponding to the former chiefdoms of Pra, Niellim, and Niou. Niellim borders on several languages of diverse families – in particular Sara, Ndam, and Laal – and is influenced by the local ''lingua franca'', Baguirmi; it has itself strongly influenced Laal, but also apparently has been influenced by Laal, or a relative of Laal, since much of the common Laal–Niellim vocabulary is not Bua. It is notably homogeneous. As a small minority in Chad, its speakers usually have to learn other languages, mostly (as of 1974) Baguirmi, Sara, Arabic, and Bua. Phonology The consonants are: The vowels are , and as well as the diphthong ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chad
Chad (; ar, تشاد , ; french: Tchad, ), officially the Republic of Chad, '; ) is a landlocked country at the crossroads of North and Central Africa. It is bordered by Libya to the north, Sudan to the east, the Central African Republic to the south, Cameroon to the southwest, Nigeria to the southwest (at Lake Chad), and Niger to the west. Chad has a population of 16 million, of which 1.6 million live in the capital and largest city of N'Djamena. Chad has several regions: a desert zone in the north, an arid Sahelian belt in the centre and a more fertile Sudanian Savanna zone in the south. Lake Chad, after which the country is named, is the second-largest wetland in Africa. Chad's official languages are Arabic and French. It is home to over 200 different ethnic and linguistic groups. Islam (55.1%) and Christianity (41.1%) are the main religions practiced in Chad. Beginning in the 7th millennium BC, human populations moved into the Chadian basin in great numbe ...

Palatal Consonant
Palatals are consonants articulated with the body of the tongue raised against the hard palate (the middle part of the roof of the mouth). Consonants with the tip of the tongue curled back against the palate are called retroflex. Characteristics The most common type of palatal consonant is the extremely common approximant , which ranks as among the ten most common sounds in the world's languages. The nasal is also common, occurring in around 35 percent of the world's languages, in most of which its equivalent obstruent is not the stop , but the affricate . Only a few languages in northern Eurasia, the Americas and central Africa contrast palatal stops with postalveolar affricates—as in Hungarian, Czech, Latvian, Macedonian, Slovak, Turkish and Albanian. Consonants with other primary articulations may be palatalized, that is, accompanied by the raising of the tongue surface towards the hard palate. For example, English (spelled ''sh'') has such a palatal component ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trill Consonant
In phonetics, a trill is a consonantal sound produced by vibrations between the active articulator and passive articulator. Standard Spanish as in , for example, is an alveolar trill. A trill is made by the articulator being held in place and the airstream causing it to vibrate. Usually a trill vibrates for 2–3 contacts, but may be up to 5, or even more if geminate. However, trills may also be produced with only one contact. While single-contact trills are similar to taps and flaps, a tap or flap differs from a trill in that it is made by a muscular contraction rather than airstream. Phonemic trills Trill consonants included in the International Phonetic Alphabet: * – Voiced alveolar trill * – Voiceless alveolar trill * – Voiced bilabial trill * – Voiceless bilabial trill * – Voiced retroflex trill * – Voiced uvular trill * – Voiceless uvular trill * – voiced epiglottal trill * – voiceless epiglottal trill In addition, * – velopharyngeal ...

Approximant Consonant
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 (as in ''rest'') and semivowels like and (as in ''yes'' and ''west'', respectively), as well as lateral approximants like (as in ''less''). Terminology Before Peter Ladefoged coined the term "approximant" in the 1960s, the terms "frictionless continuant" and "semivowel" were used to refer to non-lateral approximants. In phonology, "approximant" is also a distinctive feature that encompasses all sonorants except nasals, including vowels, taps and trills. Semivowels Some approximants resemble vowels in acoustic and articulatory properties and the terms ''semivowel'' and ''glide'' are often used for these non-syllabic vowel-like segme ...

Nasal Stop
In 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 , and , 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. Definition Nearly all nasal consonants are nasal occlusives, in which air escapes through the nose but not through the mouth, as it is blocked (occluded) by the lips or tongue. The oral cavity still acts as a resonance chamber for the sound. Rarely, non-occlusive consonants may be nasalized. Most nasals are voiced, and in fact, the nasal sounds and are among the most common sounds cross-linguistically. Voiceless nasals occur in a few languages such as Burmese, Welsh, Icelandic and ...

Fricative Consonant
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 (the final consonant of ''Bach''); or the side of the tongue against the molars, in the case of Welsh (appearing twice in the name ''Llanelli''). This turbulent airflow is called frication. A particular subset of fricatives are the sibilants. When forming a sibilant, one still is forcing air through a narrow channel, but in addition, the tongue is curled lengthwise to direct the air over the edge of the teeth. English , , , and are examples of sibilants. The usage of two other terms is less standardized: "Spirant" is an older term for fricatives used by some American and European phoneticians and phonologists. "Strident" could mean just "sibilant", but some authors include also labiodental and uvular fricatives in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Implosive Consonant
Implosive consonants are a group of stop consonants (and possibly also some affricates) with a mixed glottalic ingressive and pulmonic egressive airstream mechanism.''Phonetics for communication disorders.'' Martin J. Ball and Nicole Müller. Routledge, 2005. 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 the International Phonetic Alphabet, implosives are indicated by modifying the top of a letter (voiced stop) with a rightward-facing hook: . Articulation During the occlusion of the stop, pulling the glottis downward rarefies the air in the vocal tract. The stop is then released. In languages whose implosives are particularly salient, that may result in air rushing into the mouth before it flows out again with the next vowel. To ...

Prenasalized Consonant
Prenasalized consonants are phonetic sequences of a nasal and an obstruent (or occasionally a non-nasal sonorant such as ) that behave phonologically like single consonants. The primary reason for considering them to be single consonants, rather than clusters as in English ''finger'' or ''member'', lies in their behaviour; however, there may also be phonetic correlates which distinguish prenasalized consonants from clusters. Because of the additional difficulty in both articulation and timing, prenasalized fricatives and sonorants are not as common as prenasalized stops or affricates, and the presence of the former implies the latter. In most languages, when a prenasalized consonant is described as "voiceless", it is only the oral portion that is voiceless, and the nasal portion is modally voiced. Thus, a language may have "voiced" and "voiceless" . However, in some Southern Min (including Taiwanese) dialects, voiced consonants are preceded by voiceless prenasalization: . Yeyi ...

Voice (phonetics)
Voice or voicing is a term used in phonetics and phonology to characterize speech sounds (usually consonants). Speech sounds can be described as either voiceless (otherwise known as ''unvoiced'') or voiced. The term, however, is used to refer to two separate concepts: *Voicing can refer to the ''articulatory process'' in which the vocal folds vibrate, its primary use in phonetics to describe phones, which are particular speech sounds. *It can also refer to a classification of speech sounds that tend to be associated with vocal cord vibration but may not actually be voiced at the articulatory level. That is the term's primary use in phonology: to describe phonemes; while in phonetics its primary use is to describe phones. For example, voicing accounts for the difference between the pair of sounds associated with the English letters "s" and "z". The two sounds are transcribed as and to distinguish them from the English letters, which have several possible pronunciations, depe ...

Voicelessness
In linguistics, voicelessness is the property of sounds being pronounced without the larynx vibrating. Phonologically, it is a type of phonation, which contrasts with other states of the larynx, but some object that the word phonation implies voicing and that voicelessness is the lack of phonation. The International Phonetic Alphabet has distinct letters for many voiceless and modally voiced pairs of consonants (the obstruents), such as . Also, there are diacritics for voicelessness, and , which is used for letters with a descender. Diacritics are typically used with letters for prototypically voiced sounds, such as vowels and sonorant consonants: . In Russian use of the IPA, the voicing diacritic may be turned for voicelessness, e.g. . Voiceless vowels and other sonorants Sonorants are sounds such as vowels and nasals that are voiced in most of the world's languages. However, in some languages sonorants may be voiceless, usually allophonically. For example, the Japanese w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
