Voice enhancement method and apparatus, electronic device, and storage medium

An electronic device, comprising a processor, a memory, and a program or an instruction stored in the memory and executable on the processor, wherein the program or the instruction, when executed by the processor, causes the electronic device to perform:

• extracting first excitation information and first envelope information from a first frequency domain signal corresponding to a first voice signal, wherein the first voice signal comprises a noise signal and a first clean voice signal;
• performing optimal excitation codebook matching on the first excitation information to obtain second excitation information;
• performing optimal envelope codebook matching on the first envelope information to obtain second envelope information;
• synthesizing target spectral information based on the first excitation information, the second excitation information, and the second envelope information;
• and
• performing voice enhancement processing on the first voice signal based on the target spectral information.

A non-transitory readable storage medium, wherein the non-transitory readable storage medium stores a program or an instruction, wherein the program or the instruction, when executed by a processor of an electronic device, causes the electronic device to perform:

• extracting first excitation information and first envelope information from a first frequency domain signal corresponding to a first voice signal, wherein the first voice signal comprises a noise signal and a first clean voice signal;
• performing optimal excitation codebook matching on the first excitation information to obtain second excitation information;
• performing optimal envelope codebook matching on the first envelope information to obtain second envelope information;
• synthesizing target spectral information based on the first excitation information, the second excitation information, and the second envelope information;
• and
• performing voice enhancement processing on the first voice signal based on the target spectral information.
