Bilabial trill
- Bilabial trill
The bilabial trill is a type of
consonant al sound, used in some spokenlanguage s. The symbol in theInternational Phonetic Alphabet that represents this sound is IPA|ʙ (a character used as a lower case form of B inJaŋalif and similar alphabets), and the equivalentX-SAMPA symbol is B.In many of the languages where the bilabial trill occurs, it occurs only as part of a prenasalised bilabial stop with trilled release, IPA| [mbʙ] . This developed historically from a prenasalized stop before a relatively high
back vowel , such as IPA| [mbu] . In such instances, these sounds are usually still limited to the environment of a following IPA| [u] .There is also a very rare voiceless alveolar bilabially trilled affricate, IPA| [t̪͡ʙ̥] (occasionally written "tp") reported from a few words in the Chapacuran languages, Wari’ and Oro Win. The sound also appears as an
allophone of the labializedvoiceless alveolar plosive IPA|/tʷ/ of Abkhaz and Ubykh, but in those languages it is more often realised by a doubly articulated stop IPA| [t͡p] . In the Chapacuran languages, IPA| [tʙ̥] is reported almost exclusively before rounded vowels such as IPA| [o] and IPA| [y] .Features
Features of the bilabial trill:
*Itsmanner of articulation is trill, which means it is produced by vibrations of the articulators. In most instances, it is only found as the trilled release of aprenasalized stop .
*Itsplace of articulation is bilabial which means it is articulated with bothlip s.
*Itsphonation type is voiced, which means the vocal cords are vibrating during the articulation.
*It is anoral consonant , which means air is allowed to escape through the mouth.
*It is acentral consonant , which means it is produced by allowing the airstream to flow over the middle of the tongue, rather than the sides.
*Theairstream mechanism ispulmonic egressive , which means it is articulated by pushing air out of thelung s and through the vocal tract, rather than from theglottis or the mouth.Occurrence
