Abstract
A processing circuit performing a speech enhancement method processes a to-be-processed signal to generate a target signal and executes a plurality of program codes or program instructions to perform the following steps: performing Fourier transform on the to-be-processed signal to generate a spectral signal of the to-be-processed signal; performing a first noise reduction processing on the spectral signal to obtain a first intermediate signal; performing a noise analysis on the first intermediate signal to obtain a noise feature; performing a second noise reduction processing on the first intermediate signal to generate a second intermediate signal when the noise feature does not satisfy a target condition; and performing inverse Fourier transform on the second intermediate signal to generate the target signal. The first noise reduction processing is different from the second noise reduction processing.
