Abstract: Embodiments of this disclosure provide a speech signal processing method and apparatus, an electronic device, and a non-transitory computer-readable storage medium. A processing circuitry of the electronic device obtains speech feature parameters of a to-be-processed speech signal. The speech feature parameters include an initial spectrum of the to-be-processed speech signal. The processing circuitry predicts a first quantity of subband spectrum envelopes based on the speech feature parameters. The first set quantity is less than a quantity of initial spectrum coefficients included in the initial spectrum. Each of the subband spectrum envelopes corresponds to a second quantity of initial spectrum coefficients. The processing circuitry adjusts the initial spectrum based on the predicted subband spectrum envelopes to obtain an adjusted spectrum. The processing circuitry obtains an enhanced speech signal corresponding to the to-be-processed speech signal based on the adjusted spectrum.
