The voiced bilabial stop is a type of consonantal sound, used in some 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 boy. Many Indian languages, such as Hindustani, have a two-way contrast between breathy voiced /b?/ and plain /b/.

Features

Features of the voiced bilabial stop:

• 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 stop.
• Its place of articulation is bilabial, which means it is articulated with both lips.
• Its phonation is voiced, which means the vocal cords vibrate during the articulation.
• It is an oral consonant, which means air is allowed to escape through the mouth only.
• Because the sound is not produced with airflow over the tongue, the central-lateral dichotomy does not apply.
• The airstream mechanism is pulmonic, which means it is articulated by pushing air solely with the lungs and diaphragm, as in most sounds.
