Generally, the tongue-down postalveolar consonants have the tongue tip on the hollowed area (with a sublingual cavity), whereas for the tongue-down alveolar consonants, the tongue tip rests against the teeth (no sublingual cavity), which accentuates the hissing vs. hushing distinction of these sounds.
The alveolar or postalveolar clicks are a family of click consonants found only in Africa and in the Damin ritual jargon of Australia. The tongue is more or less concave (depending on the language), and is pulled down rather than back as in the palatal clicks , making a hollower sound than those consonants.
Similarly, in linguolabial consonants the tongue contacts the upper lip with the upper lip actively moving down to meet the tongue; nonetheless, the tongue is conventionally said to be active and the lip passive if for no other reason than that the parts of the mouth below the vocal tract are typically active, and those above the vocal tract ...
Postalveolar, which means it is articulated with either the tip or the blade of the tongue behind the alveolar ridge, termed respectively apical and laminal. It has a secondary articulation of velarization or pharyngealization , meaning that the back or root of the tongue approaches the soft palate (velum), or the back of the throat, respectively.
Features of postalveolar clicks: The basic articulation may be voiced, nasal, aspirated, glottalized, etc. The place of articulation is post-alveolar, and the tongue shape may be subapical, which means it is articulated with the tip of the tongue curled up. The center of the tongue moves downward to create suction.
Their place of articulation may include the postalveolar zone and the prepalate, but also a larger contact area extending towards the front alveolar zone and the back palate surface. The tongue tip is bent downwards and the tongue dorsum is raised and fronted during the production of these consonants.
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.
An apical consonant is a phone (speech sound) produced by obstructing the air passage with the tip of the tongue (apex) in conjunction with upper articulators from lips to postalveolar, and possibly prepalatal. [1] [2] It contrasts with laminal consonants, which are produced by creating an obstruction with the blade of the tongue, just behind ...
