[0043] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0044] At present, the ACE strategy can provide a higher stimulation rate, but only stimulates channels with higher envelope amplitudes, and some important low-amplitude envelope information is lost. However, the CIS strategy can only provide a lower stimulation rate when the total stimulation rate is limited, so that the time domain signal (especially the time domain fluctuation signal that is important for speaker gender recognition or tone recognition) cannot be effectively transmitted to artificial electronics. Cochlear patients.
[0045] The present invention aims at the weak signal processing ability defect of the current artificial cochlear and cochlear implant speech processing strategy, and adopts the method of double stimulation rate to overcome the limi...
