Articulatory phoneticians explain how humans produce speech sounds via the interaction of different physiological structures. Generally, articulatory phonetics is concerned with the transformation of aerodynamic energy into acoustic energy. Aerodynamic energy refers to the airflow through the vocal tract.
A dental consonant is a consonant articulated with the tongue against the upper teeth, such as /θ/, /ð/.In some languages, dentals are distinguished from other groups, such as alveolar consonants, in which the tongue contacts the gum ridge.
Coronal places of articulation include the dental consonants at the upper teeth, the alveolar consonants at the upper gum (the alveolar ridge), the various postalveolar consonants (including domed palato-alveolar, laminal alveolo-palatal, and apical retroflex) just behind that, the subapical retroflex consonants curled back against the hard palate, and linguolabial consonants with the tongue ...
For most sounds involving the tongue, the place of articulation can be sufficiently identified just by specifying the point of contact on the upper part of the mouth (for example, velar consonants involve contact on the soft palate and dental consonants involve the teeth), along with any secondary articulation such as palatalization (raising of the tongue body) or labialization (lip rounding).
Its place of articulation is alveolar, which means it is articulated with either the tip or the blade of the tongue at the alveolar ridge, termed respectively apical and laminal. Its phonation is voiced, which means the vocal cords vibrate during the articulation. It is an oral consonant, which means air is allowed to escape through the mouth only.
Its place of articulation may be; dental (behind the upper front teeth), alveolar (at the alveolar ridge), or post-alveolar (behind the alveolar ridge). It is most often apical, which means it is pronounced with the tip of the tongue. [4] Its phonation is voiced, which means the vocal cords vibrate during the articulation.
Its manner of articulation is approximant, which means it is produced by narrowing the vocal tract at the place of articulation, but not enough to produce a turbulent airstream. There are four specific variants of [ɫ]: Dental, which means it is articulated with either the tip or the blade of the tongue at the upper teeth.
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.
