Abstract

The present invention provides a method and device for processing voice signals of an electronic cochlea, including: performing pre-emphasis processing on the collected voice signals; performing frequency band division on the pre-emphasis processed voice signals to obtain N sub-band signals; wherein, Each sub-band signal corresponds to a channel, N is the number of channels, and N>0; envelope extraction is performed on each sub-band signal, and N sub-band signal envelopes corresponding to N sub-band signals are generated; according to preset Stimulus number M, select M stimulation channels in time sequence from N channels corresponding to N sub-band signals, and generate a current stimulation sequence consisting of M sub-band signal envelopes corresponding to M stimulation channels; wherein, 0

Description

technical field [0001] The invention belongs to the technical field of speech signal processing, in particular to a method and device for processing speech signals of an electronic cochlea. Background technique [0002] The main cause of deafness in most cochlear implant users is damage to hair cells rather than auditory neurons. Cochlear implant users can directly excite the residual auditory nerve in the cochlea through functional electrical stimulation. When a weak electrical pulse acts on the auditory nerve, the auditory nerve can be induced to be excited, and the excitement is transmitted to the brain along the auditory pathway to produce auditory perception. Therefore, as an alternative device, the cochlear electron replaces the functions of the outer ear, middle ear and part of the inner ear cochlea, directly converts the voice signal into a weak electrical pulse signal, and stimulates the auditory nerve to produce a nerve firing pattern similar to that of the normal...
