ABSTRACT
The development of speech is a process by which the neural network structure of brain perceives, decodes, represents, and outputs input signals. At the cortical level, the classic model of speech processing proposed two pathways leading from the auditory system the ventral stream and the dorsal stream.The ventral stream, which involved structures in the superior and middle portions of the temporal lobe, was involved in processing speech signals for perception and comprehension (speech recognition). The dorsal stream, which involved structures in the posterior frontal lobe and the posterior dorsal-most aspect of the temporal lobe and parietal operculum, had an auditory-motor integration function and was essential for speech production. However, the importance of auditory processing in central auditory nervous system(CANS) from the vestibulocochlear nerve to the auditory cortex for speech development had not been clarified.This review aims to discuss the roles and related mechanisms of the CANS in speech recognition and generation from the perspective of cognitive neuroscience, so as to provide new ideas for clinical monitoring and long-term prediction of auditory processing and speech development, and for diagnosis and treatment of clinical speech-related diseases.
