|Babbling||Babbling is the stage in a child’s speech and language development when the infant is experimenting with uttering sounds, but not yet producing any intelligible words. Babbling follows cooing and has three stages.

|Basal Fluency||See Fluency|
|Bilabial Consonant||A type of labial sound that is produced by moving the two lips together to constrict or shape the airflow. Bilabial describes the place of articulation (i.e., bi- for two and labial for lips). In English, there are four bilabial consonants:

|Breath Stream||The stream of air from the lungs used to activate the vocal folds or cords and to make sounds.|
|Broca’s Aphasia||A type of expressive (nonfluent) aphasia caused by brain damage to Broca’s area, the speech production center of the brain. Patients speak with grammatically-incomplete utterances, called telegraphic speech or agrammatism, but their receptive language remains intact. Thus, the patient has not lost the ability to understand language, but rather, he or she has lost the ability to combine words into coherent, complete utterances, whether written or verbal.
Speech sample of patient with Broca’s aphasia:
Also called Motor Aphasia.
See also Broca’s Area, Expressive Aphasia, Agrammatism.
|Broca’s Area||The region of the brain that controls speech production. Identified by Pierre Paul Broca, who reported expressive language impairments in two patients with injuries to this area of the brain. Broca’s area is located in the inferior frontal gyrus of the frontal lobe of the person’s language-dominant cerebral hemisphere (typically the left lobe).
Also known as Brodmann’s areas 44 and 45.
