摘要
A system determines a power spectral density associated with an audio signal that includes a speech signal and/or a noise signal. The system updates an autocorrelation function of the audio signal from samples in the audio signal, estimates an autocorrelation function of the speech signal from the updated autocorrelation function of the audio signal, and calculates a power spectral density of the speech signal using the estimated autocorrelation function. The system then determines the power spectral density of the audio signal from the calculated power spectral density of the speech signal.
