Thevoiced bilabial plosive orstop is a type ofconsonantal sound used in many spoken languages. The symbol in theInternational Phonetic Alphabet that represents this sound is ⟨b⟩, and the equivalentX-SAMPA symbol isb. The voiced bilabial stop occurs in English, and it is the sound denoted by the letter⟨b⟩ inobey[oʊˈbeɪ].
Itsmanner of articulation isocclusive, which means it is produced by obstructing airflow in the vocal tract. Since the consonant is also oral, with nonasal outlet, the airflow is blocked entirely, and the consonant is aplosive.
