The voiced alveolar, dental and postalveolar plosives (or stops) are types of consonantal sounds used in many spoken languages.The symbol in the International Phonetic Alphabet that represents voiced dental, alveolar, and postalveolar plosives is d (although the symbol d̪ can be used to distinguish the dental plosive, and d̠ the postalveolar), and the equivalent X-SAMPA symbol is d.
Here are features of the voiceless alveolar stop: Its manner of articulation is occlusive, which means it is produced by obstructing airflow in the vocal tract. Since the consonant is also oral, with no nasal outlet, the airflow is blocked entirely, and the consonant is a plosive. There are three specific variants of [t]:
Since the consonant is also oral, with no nasal outlet, the airflow is blocked entirely, and the consonant is a plosive. Its place of articulation is glottal, which means it is articulated at and by the vocal cords (vocal folds). It has no phonation at all, as there is no airflow through the glottis. [2]
It is an oral consonant, which means air is allowed to escape through the mouth only. It is a central consonant, which means it is produced by directing the airstream along the center of the tongue, rather than to the sides. The airstream mechanism is ejective (glottalic egressive), which means the air is forced out by pumping the glottis upward.
In addition, they restrict "plosive" for pulmonic consonants; "stops" in their usage include ejective and implosive consonants. [2] If a term such as "plosive" is used for oral non-affricated obstruents, and nasals are not called nasal stops, then a stop may mean the glottal stop; "plosive" may even mean non-glottal stop. In other cases ...
The voiced velar plosive or stop is a type of consonantal sound used in many spoken languages. Some languages have the voiced pre-velar plosive , [ 1 ] which is articulated slightly more front compared with the place of articulation of the prototypical velar plosive, though not as front as the prototypical palatal plosive .
Epiglottal and pharyngeal consonants occur at the same place of articulation. Esling (2010) describes the sound covered by the term "epiglottal plosive" as an "active closure by the aryepiglottic pharyngeal stricture mechanism" – that is, a stop produced by the aryepiglottic folds within the pharynx.
The voiceless bilabial plosive or stop is a type of consonantal sound used in most spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is p , and the equivalent X-SAMPA symbol is p .
