Alveolar stop

Last updated

In phonetics and phonology, an alveolar stop is a type of consonantal [1] sound, made with the tongue in contact with the alveolar ridge located just behind the teeth (hence alveolar), held tightly enough to block the passage of air (hence a stop consonant). [2] The most common sounds are the stops [t] [3] and [d], as in English toe and doe, and the voiced nasal [n]. The 2-D finite element mode of the front part of the midsagittal tongue can stimulate the air pressed release of an alveolar stop. [4] 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. [5]

The upcoming vowel target is adjusted to demand force and effort during the coarticulating process. [6] More generally, several kinds are distinguished:

Note that alveolar and dental stops are not always carefully distinguished. Acoustically, the two types of sounds are similar, and it is rare for a language to have both types, though there are languages which have both and in which they are phonemic, such as in the Bengali spoken in Bangladesh (as opposed to that spoken in West Bengal).

If necessary, an alveolar consonant can be transcribed with the combining equals sign below ◌͇, as with for the voiceless alveolar stop. A dental consonant can be transcribed with the combining bridge below , and a postalveolar consonant with the retraction diacritic, the combining minus sign below .
