Abstract: Voice recognition is a key skill for successful human communication,but patients with voice recog-nition defects often suffer from the inability to accurately identify the speaker's identity.Phonagnosia refers to the difficulty in identifying a speaker by voice alone when hearing ability is not impaired.From the perspective of brain injury,the symptoms can be divided into congenital phonagnosia and developmental phonagnosia,and congenital phonagnosia is related to the dysfunction of the functional connection between the temporal lobe and the amygdala.The damaged brain areas in patients with acquired speech recognition defect mainly include the temporal lobe and the frontal lobe.In the future,more attention should be paid to the screening methods,neural mechanisms and differ-ences between patients with speech recognition deficiency and other patients with hearing and cognitive impairment.
