1. A method for controlling adaptivity of noise cancellation, the method comprising: receiving an audio signal from a first microphone and another audio signal from a second microphone: determining a pitch salience of the audio signal, the audio signal and the another audio signal both comprising a speech component and a noise component; and determining a coefficient that represents a cross-correlation between the audio signal and the another audio signal of one of the speech component and the noise component that exists in both the audio signal and the another audio signal; generating a modified audio signal for the audio signal based on the another audio signal and the coefficient; and adapting the coefficient when the pitch salience satisfies a threshold.
