The present study investigated speech monitoring behaviour of a patient with Broca’s aphasia and 11 healthy controls. Speech monitoring was examined in a speaking situation with normal auditory feedback, a speaking situation with white noise, and in a listening situation in which errors had to be detected in the speech of someone else. The results demonstrated that in monitoring his own speech, the patient strongly relied on prearticulatory monitoring, in contrast to the healthy controls. Furthermore, patient G. produced many phonological errors and had trouble repairing these errors, whereas he produced fewer semantic errors and had less trouble repairing these errors. This suggests that there is a relationship between production impairment and monitoring impairment. This could indicate that prearticulatory monitoring in this patient is production based, or that capacity limitations are responsible for the selective monitoring impairment.
