The voiced bilabial plosive or stop is a type of consonantal sound used in many spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is b , and the equivalent X-SAMPA symbol is b. The voiced bilabial stop occurs in English, and it is the sound denoted by the letter b in obey [oʊˈbeɪ].
In phonetics and phonology, a bilabial stop is a type of consonantal sound, made with both lips (hence bilabial), held tightly enough to block the passage of air (hence a stop consonant). The most common sounds are the stops [p] and [b], as in English pit and bit, and the voiced nasal [m]. [1] More generally, several kinds are distinguished:
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.
Bilabial consonants are very common across languages. Only around 0.7% of the world's languages lack bilabial consonants altogether, including Tlingit , Chipewyan , Oneida , and Wichita , [ 1 ] though all of these have a labial–velar approximant /w/.
Features of the bilabial ejective: 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. Its place of articulation is bilabial, which means it is articulated with both ...
So-called voiced aspirated consonants are nearly always pronounced instead with breathy voice, a type of phonation or vibration of the vocal folds. The modifier letter ʰ after a voiced consonant actually represents a breathy-voiced or murmured consonant, as with the "voiced aspirated" bilabial stop bʰ in the Indo-Aryan languages.
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 .
