Description

technical field [0001] The invention relates to the fields of electronic information and medical equipment, in particular to an in vivo system of an electronic cochlear debugging platform. Background technique [0002] Cochlear implants, also known as cochlear implants, are currently the only devices that can help patients with severe deafness and total deafness recover their hearing. Through the speech processing algorithm, the cochlear implant converts the speech signal into electrical stimulation and directly acts on the auditory nerve fibers, so that the patient can produce a nerve firing pattern similar to that of the normal human ear, thereby forming a sense of hearing. At present, the cochlear electronic products used clinically in China all come from abroad, and their speech processing algorithms cannot meet the recognition requirements of Chinese. The development of speech processing algorithms suitable for Chinese characteristics needs to be carried out on the coch...
