Bilabial stop

Last updated

In phonetics and phonology, a bilabial stop is a type of consonantal sound, made with both lips (hence bilabial), held tightly enough to block the passage of air (hence a stop consonant). The most common sounds are the stops [p] and [b], as in English pit and bit, and the voiced nasal [m]. [1] More generally, several kinds are distinguished:

In phonology, an allophone is a set of multiple possible spoken sounds – or phones – or signs used to pronounce a single phoneme in a particular language. For example, in English, and the aspirated form are allophones for the phoneme, while these two are considered to be different phonemes in some languages such as Hindi and Thai. On the other hand, in Spanish, and are allophones for the phoneme, while these two are considered to be different phonemes in English.

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.

<span class="mw-page-title-main">Manner of articulation</span> Configuration and interaction of the articulators when making a speech sound

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.

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.

A voiced bilabial implosive is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɓ⟩, and the equivalent X-SAMPA symbol is b_<.

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 sound production and constitutes the first part of this process, which is called initiation.

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 and phonology, a uvular stop is a type of consonantal sound, made with the back of the tongue in contact with the uvula, which hangs down in front of the throat, held tightly enough to block the passage of air.

In phonetics and phonology, a velar stop is a type of consonantal sound, made with the back of the tongue in contact with the soft palate, held tightly enough to block the passage of air. The most common sounds are the stops and, as in English cut and gut. More generally, several kinds are distinguished:

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.

In phonetics and phonology, an alveolar stop is a type of consonantal sound, made with the tongue in contact with the alveolar ridge located just behind the teeth, held tightly enough to block the passage of air. The most common sounds are the stops and, as in English toe and doe, and the voiced nasal. The 2-D finite element mode of the front part of the midsagittal tongue can stimulate the air pressed release of an alveolar stop. Alveolar consonants in children's productions have generally been demonstrated to undergo smaller vowel-related coarticulatory effects than labial and velar consonants, thus yielding consonant-specific patterns similar to those observed in adults.

A voiceless bilabial implosive is a rare consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɓ̥⟩ or ⟨pʼ↓⟩. A dedicated IPA letter, ⟨ƥ⟩, was withdrawn in 1993.

In phonetics and phonology, a palatal stop is a type of consonantal sound, made with the body of the tongue in contact with the hard palate, held tightly enough to block the passage of air. Note that a stop consonant made with the tip of the tongue curled back against the palate is called a retroflex stop.

In phonetics, an occlusive, sometimes known as a stop, is a consonant sound produced by occluding airflow in the vocal tract, but not necessarily in the nasal tract. The duration of the block is the occlusion of the consonant. An occlusive may refer to one or more of the following, depending on the author:

A voiceless velar implosive is a rare consonantal sound, used in some oral languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɠ̊⟩ or ⟨kʼ↓⟩. A dedicated IPA letter, ⟨ƙ⟩, was withdrawn in 1993.

Wadiyara Koli is an Indo-Aryan language of the Gujarati group. It is spoken by the Wadiyara people, who originate from Wadiyar in Gujarat; many of whom are thought to have migrated to Sindh in the early twentieth century, following the onset of famine. The Wadiyara people are affiliated with the Bhil people and Koli people, but are generally more inclined towards associating themselves with the Koli; they are often regarded as a subgroup of the latter.
