摘要:
An exemplary method of enhancing pitch of an audio signal presented to a cochlear implant patient includes 1) determining a frequency spectrum of an audio signal presented to a cochlear implant patient, the frequency spectrum comprising a plurality of frequency bins that each contain spectral energy, 2) generating a modified spectral envelope of the frequency spectrum of the audio signal, 3) identifying each frequency bin included in the plurality of frequency bins that contains spectral energy above the modified spectral envelope and each frequency bin included in the plurality of frequency bins that contains spectral energy below the modified spectral envelope, 4) enhancing the spectral energy contained in each frequency bin identified as containing spectral energy above the modified spectral envelope, and 5) compressing the spectral energy contained in each frequency bin identified as containing spectral energy below the modified spectral envelope. Corresponding methods and systems are also disclosed.
