Avoiced bilabial affricate ([b͜β] inIPA) is a rareaffricate consonant that is initiated as abilabial stop[b] and released as avoiced bilabial fricative[β]. It has not been reported to occurphonemically in any language.

Features of a voiced bilabial affricate:

• Itsmanner of articulation isaffricate, which means it is produced by first stopping the airflow entirely, then allowing air flow through a constricted channel at the place of articulation, causing turbulence.
• Itsplace of articulation isbilabial, which means it is articulated with bothlips.
• Itsphonation is voiced, which means the vocal cords vibrate during the articulation.
• It is anoral consonant, which means that air is not allowed to escape through the nose.
• Because the sound is not produced with airflow over the tongue, themedian–lateral dichotomy does not apply.
• Itsairstream mechanism ispulmonic, which means it is articulated by pushing air only with theintercostal muscles andabdominal muscles, as in most sounds.
