The duration between the release of the plosive and the voice onset is called the voice onset time (VOT) or the aspiration interval. Highly aspirated plosives have a long period of aspiration, so that there is a long period of voiceless airflow (a phonetic [h]) before the onset of the vowel.
The concept of voice onset time can be traced back as far as the 19th century, when Adjarian (1899: 119) [1] studied the Armenian stops, and characterized them by "the relation that exists between two moments: the one when the consonant bursts when the air is released out of the mouth, or explosion, and the one when the larynx starts vibrating".
For the pairs of English stops, however, the distinction is better specified as voice onset time rather than simply voice: In initial position, /b d g/ are only partially voiced (voicing begins during the hold of the consonant), and /p t k/ are aspirated (voicing begins only well after its release).
In fact, the labial plosive is the least stable of the voiceless stops in the languages of the world, as the unconditioned sound change [p] → [f] (→ [h] → Ø) is quite common in unrelated languages, having occurred in the history of Classical Japanese, Classical Arabic and Proto-Celtic, for instance.
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.
Obstruents are subdivided into: plosives (oral stops), such as [p, t, k, b, d, ɡ], with complete occlusion of the vocal tract, often followed by a release burst ...
Postalveolar (post-alveolar) consonants are consonants articulated with the tongue near or touching the back of the alveolar ridge.Articulation is farther back in the mouth than the alveolar consonants, which are at the ridge itself, but not as far back as the hard palate, the place of articulation for palatal consonants.
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 ...
