Abstract
The application discloses a microphone voice noise reduction method and device, earphones and a computer readable storage medium, and is applied to the technical field of earphones. The method determines microphone full-band voice spectrum energy according to an adaptive filter and collected bone conduction voice spectrum and microphone noise voice spectrum, carries out noise estimation according to the microphone full-band voice spectrum energy and the microphone noise voice spectrum, obtains first microphone noise spectrum energy, acquires noise spectrum energy to be corrected, corrects the noise spectrum energy to be corrected through the first microphone noise spectrum energy, obtains corrected microphone noise spectrum energy, and finally carries out noise reduction on the microphone noise voice spectrum through the corrected microphone noise spectrum energy.
